● Quick Answer
- For most RVs: 20×40×12 for standard travel trailers, 24×50×14 for fifth wheels, 24×60×14 for Class A motorhomes. Height is critical — always add 18-24 inches above the roof AC.
- For most trucks: 12×26×7 for full-size pickups (F-150, Silverado), 14×26×8 for crew cabs and HD pickups, 14×31×10 for lifted trucks with roof racks.
- Width rule of thumb: Measure vehicle width including mirrors, add 3-4 feet of clearance per vehicle, multiply by number of vehicles.
- Length rule of thumb: Vehicle length (including hitch and tongue for RVs) plus 4-6 feet of walk-around clearance.
- Height rule of thumb: Vehicle height (including roof AC, satellite, antenna) plus 18-24 inches of walk-under clearance.
- When in doubt: Order the larger size. Upgrading later costs 2-3x more than ordering correctly the first time.

Picking the wrong carport size for your RV or truck is the single most expensive mistake you can make — a 12-foot-tall carport that "should fit" your Class A motorhome doesn't once you factor in the roof AC, and a 20-foot carport that "should fit" your travel trailer leaves no room for the tongue and hitch. Understanding carport sizes before you order means knowing exact clearance for your specific rig — RV type, truck configuration, or any other vehicle. This guide eliminates the guesswork with vehicle-specific size tables, measurement formulas, and the clearance math our installers use when customers call asking "will my fifth wheel fit?" or "will my F-350 fit under 14 feet?"
You'll find RV-specific size tables (travel trailer, pop-up, truck camper, fifth wheel, toy hauler, Class A/B/C motorhome) and truck-specific size tables (every pickup class from mid-size to dually with lift kit), standard carport dimensions by width, measurement guides to confirm your rig's exact footprint, climate-based sizing adjustments, and the single question that determines whether you need 2 extra feet or 8 extra feet of clearance. By the end you'll know exactly what size carport to order for your RV, truck, or any other vehicle — down to the width in feet and the height in inches.
The 3 Carport Dimensions You Must Measure
Metal carports are quoted and ordered in three dimensions: Width × Length × Height. Understanding what each one means — and how to add the right clearance to each for your specific RV or truck — determines whether your carport fits correctly or forces an expensive replacement.
Width (W) — The Side-to-Side Measurement
Carport width runs perpendicular to how a vehicle drives in. The usable interior width is typically 1-2 feet less than the ordered width because of the frame columns. A 20-foot-wide carport gives you roughly 18 feet of usable parking width between columns — enough for a travel trailer with slides deployed on one side.
- Formula: (vehicle width + 36 inches) × number of vehicles
- Example for trucks: Two full-size pickups at 80 inches wide = (80+36) × 2 = 232 inches = 19 feet 4 inches. Round up to a 20-foot-wide carport.
- Example for RVs: A travel trailer at 96 inches wide (with awning retracted) needs 96+36 = 132 inches = 11 feet of width. The nearest standard RV cover width is 18 feet — the extra width handles slides and walking around.
Length (L) — The Front-to-Back Measurement
Carport length runs parallel to how the vehicle drives in. For RVs, this is where most buyers under-measure — a "30-foot travel trailer" is 32-34 feet from hitch to bumper.
- Formula: longest vehicle length + 4-6 feet (walk-around clearance). For RVs, use hitch-to-bumper length.
- Example for trucks: A 20-foot pickup needs 24-26 feet of carport length.
- Example for RVs: A 30-foot travel trailer (32-34 feet hitch-to-bumper) needs 38-40 feet of carport length.
Height (H) — The Eave Height
Carport height refers to the eave height — the height from the ground to where the roof meets the sidewalls. The peak of the roof (center) is 1-2 feet higher depending on roof style. For RVs, roof-mounted equipment is what determines height requirements, not the cabin roof itself.
- Formula: tallest point of vehicle + 18-24 inches (walk-under clearance)
- Example for trucks: An F-150 pickup stands 76 inches tall. Add 18-24 inches = 8 feet eave height is the minimum.
- Example for RVs: A Class A motorhome at 12 feet with a 14-inch roof AC = 13 feet 2 inches total height. Add 24 inches = need 15-foot eave minimum, so order 16 feet to be safe.
Standard Carport Sizes by Width
While every carport we build is custom to your exact dimensions, these are the most-ordered widths and what they fit.
| Width | Usable Interior | Best For | Common Lengths |
|---|---|---|---|
| 12 ft | ~10 ft | 1 car, sedan, compact SUV, pop-up camper, truck camper | 21, 26, 31, 36 ft |
| 14 ft | ~12 ft | 1 full-size truck, HD pickup, lifted truck, bass boat | 21, 26, 31, 36 ft |
| 18 ft | ~16 ft | 2 compact cars, small travel trailer | 21, 26, 31, 41 ft |
| 20 ft | ~18 ft | 2 full-size vehicles, standard travel trailer, Class B camper van | 21, 26, 31, 41, 51 ft |
| 22 ft | ~20 ft | 2 trucks with clearance | 26, 31, 41 ft |
| 24 ft | ~22 ft | 3 compact cars, Class C motorhome, fifth wheel, travel trailer with slides | 26, 31, 41, 51, 60 ft |
| 26 ft | ~24 ft | 3 compact-to-midsize vehicles, large fifth wheel | 26, 31, 41, 51, 60 ft |
| 28 ft | ~26 ft | 3 full-size vehicles, Class A motorhome + car combo, toy hauler | 26, 31, 41, 51, 60 ft |
| 30 ft | ~28 ft | 3 trucks, RV + 2 car combo, luxury Class A motorhome | 31, 41, 51, 60, 70 ft |
What Size Carport Do I Need for My RV?
RVs are the most dimensionally-variable vehicle you'll park under a carport. A 24-foot Class B camper van and a 42-foot Class A motorhome both qualify as "RVs" but need completely different carport sizes. Here's the exact breakdown by RV type.
RV Carport Size Chart
| RV Type | Typical Length | Typical Height (with AC) | Recommended Carport | Price Range |
|---|---|---|---|---|
| Pop-up camper / tent trailer | 10-16 ft | 7-8 ft folded | 12×21×8 | $2,195+ |
| Teardrop trailer | 10-16 ft | 5-7 ft | 12×21×8 | $2,195+ |
| Truck camper (slide-in) | 8-12 ft (on truck) | 10-11 ft (on truck) | 12×26×12 | $2,595+ |
| Small travel trailer | 16-24 ft | 10-11 ft | 18×30×12 | $3,795+ |
| Standard travel trailer | 25-32 ft | 10-11 ft | 20×40×12 | $5,395+ |
| TT with slides (deployed) | 28-34 ft | 10-11 ft | 24×40×12 | $6,795+ |
| Class B camper van (Sprinter, Transit) | 17-24 ft | 9-10 ft | 20×30×12 | $3,995+ |
| Class C motorhome | 20-33 ft | 11-12 ft | 24×40×14 | $6,795+ |
| Fifth wheel (standard) | 28-38 ft | 12-13 ft (incl. hump) | 24×50×14 | $7,995+ |
| Fifth wheel (large) | 36-42 ft | 12-13 ft | 28×50×14 | $8,795+ |
| Toy hauler | 28-45 ft | 12-13 ft | 28×50×14 to 28×60×14 | $8,795+ |
| Class A motorhome (standard) | 28-36 ft | 12-14 ft (with AC + satellite) | 24×60×14 | $9,195+ |
| Class A motorhome (luxury) | 40-45 ft | 13-14 ft (with AC + satellite) | 28×60×16 | $11,595+ |
Critical RV Sizing Mistakes to Avoid
- Forgetting the roof AC: Standard roof-mounted AC units add 10-14 inches above the roof line. Satellite dishes add another 6-10 inches. Measure your tallest actual point, not just the roof line.
- Forgetting the hitch and tongue: A "30-foot travel trailer" measures 30 feet from front wall to back bumper — but is 32-34 feet total from hitch to bumper. Order the carport based on hitch-to-bumper length.
- Not accounting for slides: If you'll ever use the camper while under the cover (common for seasonal campers on your own property), measure width with all slides fully extended, not retracted.
- Underestimating fifth wheel height: Fifth wheels have a raised sleeping area over the fifth wheel coupler. That section is 12-13 feet tall even if the main cabin is 10-11 feet. Measure the hump height, not the cabin.
What Size Carport Do I Need for My Truck?
Pickup trucks are the most-common vehicle covered by carports in the US. Here are the exact size recommendations by truck class and specific model.
Pickup Truck Size Chart
| Truck Example | Approx. Dimensions (L×W×H) | Recommended Carport (W×L×H) | Why |
|---|---|---|---|
| Mid-size pickup (Tacoma, Ranger, Colorado) | 17 ft × 6.3 ft × 5.9 ft | 12×21×7 | Tight fit |
| Full-size pickup (F-150, Silverado 1500, Ram 1500) | 19-20 ft × 6.7 ft × 6.3 ft | 12×26×7 or 14×26×8 | Standard fit |
| Full-size crew cab long bed (F-150 CrewCab 6.5' bed) | 21-22 ft × 6.7 ft × 6.5 ft | 14×26×8 or 12×31×8 | Extra length |
| Heavy duty pickup (F-250, F-350, Silverado 2500) | 21-22 ft × 6.8 ft × 6.6 ft | 14×26×8 or 14×31×9 | Taller frame |
| HD pickup with lift kit or dually (F-350 dually) | 22-23 ft × 7.9 ft × 7.0 ft | 18×31×9 (dually), 14×31×10 (lifted) | Wider or taller |
| Pickup with camper shell | Add 12-18 inches to height | Add 1 ft to standard height | Shell above cab |
| Pickup with slide-in truck camper | Add 3-5 ft to height | 12×26×12 minimum | Camper on bed |
Common Truck Carport Mistakes
- Forgetting the lift kit: A 4-inch suspension lift plus 35-inch tires adds roughly 6 inches of height. Order a 9-foot carport instead of 8-foot.
- Forgetting the dually: Dually trucks are 15-18 inches wider at the rear axle than their single-rear-wheel counterparts. 14-foot carports that fit a regular F-350 won't fit an F-350 dually.
- Forgetting mirrors: Full-size trucks are 80 inches wide at the body but 95-100 inches wide at the mirrors. The clearance formula uses the mirror width, not body width.
- Underestimating long-bed length: An F-150 regular cab is 17 feet long. An F-150 CrewCab long-bed is 22 feet long. Measure your specific configuration.
What Size Carport Do I Need for a Car or SUV?
While RVs and trucks drive most carport purchases, many buyers also protect daily driver cars and SUVs — often alongside the RV or truck in a multi-vehicle configuration.
Car and SUV Size Chart
| Vehicle Type | Approx. Dimensions (L×W×H) | Recommended Carport | Fit Note |
|---|---|---|---|
| Compact sedan (Civic, Corolla) | 15 ft × 5.8 ft × 4.7 ft | 12×21×6 | Snug |
| Mid-size sedan (Camry, Accord, Altima) | 16 ft × 6 ft × 4.9 ft | 12×21×7 or 12×26×7 | Standard |
| Full-size sedan (Charger, Impala) | 17 ft × 6.3 ft × 5 ft | 12×26×7 | Standard |
| Compact SUV (CR-V, RAV4, Rogue) | 15 ft × 6.1 ft × 5.6 ft | 12×21×7 | Standard |
| Mid-size SUV (Highlander, Pilot, Explorer) | 16 ft × 6.5 ft × 5.9 ft | 12×26×7 | Standard |
| Full-size SUV (Suburban, Tahoe, Expedition) | 18-19 ft × 6.7 ft × 6.3 ft | 12×26×8 or 14×26×8 | Taller frame |
| SUV with roof rack / cargo box | Add 12-18 inches to height | Step up to 8-9 ft eave | Rack clearance |
| Minivan (Odyssey, Pacifica, Sienna) | 17 ft × 6.6 ft × 5.9 ft | 12×26×7 | Standard |
What Size Carport Do I Need for a Boat?
Boat carports are measured based on boat-plus-trailer dimensions, not just the boat hull. The trailer adds 2-4 feet of length behind the hull and 2-3 feet of height depending on trailer height.
| Boat Type | Boat Length | Boat + Trailer Length | Recommended Carport |
|---|---|---|---|
| Jon boat / small aluminum | 12-16 ft | 16-20 ft | 12×21×7 |
| Bass boat (16-18 ft) | 16-18 ft | 20-22 ft | 12×26×8 |
| Pontoon boat (18-22 ft) | 18-22 ft | 22-26 ft | 12×26×9 or 14×26×9 |
| Deck boat / larger pontoon (22-25 ft) | 22-25 ft | 26-29 ft | 14×31×10 |
| Ski/wakeboard boat (20-24 ft) | 20-24 ft | 24-28 ft | 14×31×10 (tall tower) |
| Cuddy cabin / small cruiser (24-28 ft) | 24-28 ft | 28-32 ft | 18×36×10 |
| Cabin cruiser (28-35 ft) | 28-35 ft | 32-40 ft | 18×41×12 |
Boats with tall accessory stacks (ski/wakeboard towers) can add 4-6 feet of height. Measure your boat with the tower deployed if you leave it up for storage.
What Size for Motorcycles, UTVs, and Equipment?
Not every carport covers a full-size vehicle. These are the common size recommendations for smaller equipment, which many RV and truck owners also need to cover.
| Equipment | Typical Dimensions | Recommended Carport |
|---|---|---|
| Motorcycle (standard) | 7 ft × 3 ft × 4 ft | 12×16×7 or 12×21×7 (for 2-3 bikes) |
| Motorcycle (touring, Gold Wing) | 8-9 ft × 3 ft × 5 ft | 12×21×7 |
| ATV / 4-wheeler | 7 ft × 4 ft × 4 ft | 12×16×7 or 12×21×7 |
| UTV / Side-by-side (Ranger, Polaris) | 10 ft × 5 ft × 6 ft | 12×21×7 |
| Riding lawn mower | 6-8 ft × 4-5 ft × 4 ft | 12×16×7 |
| Zero-turn mower (commercial) | 7 ft × 5 ft × 4 ft | 12×16×7 or 12×21×7 |
| Compact tractor (sub-25 hp) | 10 ft × 5 ft × 7 ft (with ROPS) | 14×21×9 |
| Utility tractor (25-50 hp) | 12 ft × 6 ft × 8 ft (with ROPS) | 14×26×10 |
| Golf cart | 8 ft × 4 ft × 6 ft (with roof) | 12×16×7 |
| Jet ski on trailer | 13 ft × 6 ft × 5 ft | 12×21×7 |
2-Car, 3-Car, and Multi-Vehicle Carport Dimensions
2-Car Carport Dimensions
The standard 2-car carport width is 20 feet, which fits two full-size vehicles side-by-side with 3-4 feet of clearance per vehicle. Variations:
- 18×21 ($2,795+): Compact 2-car — two compact sedans or SUVs. Tight clearance.
- 20×21 ($2,995+): Standard 2-car minimum. Two mid-size vehicles.
- 20×26 ($3,395+): Most-ordered 2-car size. Two full-size vehicles with normal clearance.
- 22×26 ($3,595+): Wide 2-car. Two trucks or SUVs with extra side clearance.
- 20×31 ($3,795+): Long 2-car. Standard width + 5 extra feet for workbench or storage.
- 24×26 ($4,195+): Oversize 2-car. Two full-size trucks with generous clearance.
3-Car Carport Dimensions
The standard 3-car carport width is 24-30 feet. The right width depends on vehicle size — 24 feet fits three sedans, 30 feet fits three full-size pickups.
- 24×21 ($4,195+): 3-car compact. Three sedans in a tight row. Not for trucks.
- 24×26 ($4,195+): Standard 3-car minimum. Three compact or mid-size vehicles.
- 28×26 ($4,395+): 3-car with truck clearance. Three full-size vehicles.
- 30×31 ($5,295+): Full 3-truck carport. Standard choice for three pickups.
- 24×31 ($4,795+): Most-ordered 3-car size. Three vehicles plus workshop depth.
- 30×41 ($6,695+): RV + 2 cars combo. Center RV bay with flanking car bays.
Carport Height Guide: Exact Clearances by Vehicle
Carport height is the dimension most buyers under-estimate — especially for RVs with roof-mounted equipment. Here's the exact clearance you need for every vehicle type, measured in eave height (the height from ground to where the roof meets the sidewalls).
| Vehicle / Equipment | Minimum Eave Height | Recommended Eave Height |
|---|---|---|
| Compact sedan | 6 ft | 7 ft |
| Full-size sedan or coupe | 6 ft | 7 ft |
| SUV | 7 ft | 8 ft |
| Pickup truck (standard) | 7 ft | 8 ft |
| Pickup truck (lifted or HD) | 8 ft | 9 ft |
| Pickup with roof rack / cargo | 8 ft | 9 ft |
| Pop-up / teardrop camper | 7 ft | 8 ft |
| Travel trailer (standard) | 11 ft | 12 ft |
| Travel trailer with roof AC | 12 ft | 12-14 ft |
| Fifth wheel | 13 ft | 14 ft |
| Class A motorhome | 13 ft | 14-16 ft |
| Class A with roof AC + satellite | 14 ft | 16 ft |
| Truck camper (slide-in) | 11 ft | 12 ft |
| Semi-truck day cab | 12 ft | 13 ft |
| Semi-truck sleeper | 13 ft | 14 ft |
Rule of thumb for height: measure the tallest point of your vehicle (not just the roof — include roof-mounted AC, satellite dish, antenna, roof rack, cargo box). Add 18-24 inches of walk-under clearance. That's your minimum eave height.
Climate Adjustments: Snow, Wind, and Hurricane Zones
Climate affects carport sizing in two ways: snow accumulation requires taller eaves (snow sliding off a vertical roof lands in a mound next to the walls), and hurricane zones often require code-mandated vertical roof + taller eaves for structural reasons.
Snow Country Sizing Adjustments
- Add 2 feet to standard eave height: The vertical roof needed for snow country has a steeper peak that adds vehicle clearance under the eave but requires taller sidewalls for snow accumulation space.
- Add 4-6 feet to length: Snow slides off the vertical roof and accumulates at the eave. Longer carport = less snow buildup against vehicles parked near the ends.
- Choose vertical roof style: 40-50 psf snow load rating vs 20 psf for regular roof. Required in most northern US states.
Hurricane Zone Sizing Adjustments
- Add 1 foot to eave height: The 12-gauge framing and hurricane straps required in coastal zones add 6-10 inches of structural height. Order 1 extra foot of eave to compensate.
- Standard width is fine: Hurricane adjustments don't affect carport width, just framing and anchor spec.
- Vertical roof required: 140-170 mph wind rating vs 90-115 mph for regular roof.
Shade-Climate Sizing (Southwest, Desert)
- Add overhangs to shade vehicle: In the Southwest, 2-4 foot roof overhangs block low-angle sun from reaching vehicles parked beneath. Overhangs add $20-$30 per linear foot.
- Light color roof: White or light-stone roof reflects more heat than dark colors. Can reduce interior temperature under the carport by 15-25°F.
How to Measure Your RV or Truck Correctly
Manufacturer-published dimensions are a starting point, but your specific vehicle (with accessories, modifications, roof racks, mirrors) is usually 3-18 inches different from the base spec. Here's how to measure correctly.
Width Measurement
1. Park on level ground. Measure from the outermost point on one side to the outermost point on the other side.
2. Include mirrors (trucks). Full-size trucks are 95-100 inches wide at mirrors vs 80 inches at the body. Mirrors are what determines whether the vehicle fits.
3. Include dually rear axles (trucks). Dually trucks are 15-18 inches wider at the rear axle than their single-rear-wheel counterparts.
4. Include deployed slides (RVs). If you'll ever use the camper under the cover, measure with slides deployed.
Length Measurement
1. Measure from tip of hitch/tongue to back bumper (RVs). This is the full tow length. A 30-foot travel trailer typically measures 32-34 feet hitch-to-bumper.
2. Include rear-mounted spare tires. RV spare tire carriers add 6-12 inches.
3. Include rear bike racks or cargo boxes. Any accessory extending behind the back bumper counts toward length.
Height Measurement
1. Measure to the tallest point. Not the roof line — the tallest accessory on the roof. For RVs that's typically the roof AC unit.
2. Measure roof AC specifically (RVs). Standard RV roof ACs add 10-14 inches above the roof.
3. Measure satellite dish or antenna if present. Add 6-10 inches to the AC height for satellite dishes.
4. Add future accessories if planned. If you plan to add solar panels or additional AC units later, measure based on the planned final configuration.
Future-Proofing: When to Size Up
The question we ask every buyer: in 5 years, will you still own the same vehicles, or might you have a bigger truck, a camper you didn't own yet, a boat you're thinking about buying? If any of those scenarios are possible, size up now.
Signs You Should Size Up
- Your current truck is nearing the end of its life: Replacing an F-150 with an F-250 or an F-350 means 1-2 extra feet of length and 2-4 extra inches of width. Size for your next vehicle, not your current one.
- You're considering an RV, boat, or travel trailer: If there's any chance you'll own a towable recreational vehicle in the next 5 years, add 2-6 feet of length to accommodate it.
- Your current RV may be replaced with a larger one: If you own a 24-foot travel trailer now and may upgrade to a 32-footer or move to a Class A motorhome, order the larger carport now.
- Workshop or storage needs may grow: If a current 2-car carport works but you've been thinking about adding a workbench, order a larger size that accommodates both parking and workshop space.
The Cost Math of Sizing Up
Here's the economics argument for ordering 1 size larger than you need today:
- Cost to order 1 size larger today: Typically $400-$1,200 depending on build size. One-time cost.
- Cost to replace an undersized carport in year 3: Typically $4,000-$12,000 depending on build size. Includes removal of old carport, re-grading, new install. Plus the loss of the original carport's remaining 17-37 years of useful life.
- ROI of sizing up: Spending $800 extra today to avoid an $8,000 replacement in year 3 = 10x return on the upgrade investment.
Carport Size vs Price: What You'll Pay by Size
Metal carport pricing scales with size — but not linearly. A 20×30 carport costs roughly 2x the price of a 12×20, not 2.5x, because larger builds amortize the fixed costs of delivery and anchoring across more square footage. Here's the typical 2026 pricing by size:
| Size | Sq Ft | Starting Price | Cost per Sq Ft | Best For |
|---|---|---|---|---|
| 12×21×7 | 252 | $1,595 | $6.33 | 1 car / truck |
| 20×21×7 | 420 | $2,795 | $6.66 | 2 cars |
| 20×26×7 | 520 | $3,195 | $6.14 | 2 cars + storage |
| 24×26×8 | 624 | $4,195 | $6.72 | 3 cars / trucks |
| 30×31×8 | 930 | $5,295 | $5.69 | 3 trucks |
| 20×40×12 (RV) | 800 | $5,395 | $6.74 | Travel trailer |
| 24×50×14 (RV) | 1,200 | $7,995 | $6.66 | Fifth wheel |
| 28×60×16 (Class A) | 1,680 | $11,595 | $6.90 | Luxury Class A |
Across all sizes, carports average $5-$7 per square foot delivered and installed — one of the lowest cost-per-square-foot structures you can build. The size you choose should be driven by what fits your vehicles and future plans, not by trying to save $400-$1,200 on a build you'll own for 25-40 years.
Frequently Asked Questions
How tall should a carport be for an RV?
The right height depends on RV type with roof equipment. Travel trailer with roof AC: 12 feet eave. Fifth wheel with hump + AC: 14 feet eave. Class C motorhome: 14 feet eave. Standard Class A with AC: 14 feet eave. Class A with AC + satellite + antenna: 16 feet eave. Semi-truck sleeper: 14 feet eave. The 18-24 inch clearance above the tallest roof point is non-negotiable — anything less and you can't walk under the eave without crouching.
What size carport do I need for a Class A motorhome?
Class A motorhomes range from 28 to 45 feet long and 12-14 feet tall with roof equipment. For a standard 28-36 ft Class A, choose 24×60×14. For a large 34-42 ft Class A, choose 28×60×14 — most buyers in this range step up to 16-foot eave height. For a luxury 40-45 ft Class A with roof AC and satellite dish, choose 28×60×16 at $11,595+. For Class A plus a daily driver or toad vehicle under the same roof, choose 30×60×16 at $12,795+.
What size carport do I need for a fifth wheel?
Fifth wheels range 22-45 feet long with a raised sleeping area over the fifth wheel coupler that's 12-13 feet tall even if the main cabin is shorter. Standard 28-38 ft fifth wheels fit under a 24×50×14 cover at $7,995+. Large 36-42 ft fifth wheels fit under a 28×50×14 at $8,795+. Luxury 40-45 ft fifth wheels fit under a 28×60×14 at $10,195+. The 14-foot eave height is required to clear the fifth wheel hump — not optional.
What size carport do I need for a travel trailer?
Travel trailer sizing depends on length and whether you have slides. Small travel trailer (16-24 ft): 18×30×12 at $3,795+. Standard travel trailer (25-32 ft): 20×40×12 at $5,395+ (most-ordered size). Travel trailer with slides (28-34 ft): 24×40×12 at $6,795+. Extended travel trailer (33-38 ft): 24×50×14 at $7,995+. Always add the hitch and tongue length to your trailer length when sizing — a 30-foot trailer is 32-34 feet hitch-to-bumper.
What size carport for 2 trucks?
The standard 2-truck carport size is 20×26×8 at $3,195+ which fits two full-size pickups side-by-side with normal clearance. For two trucks with extra side clearance (useful for opening doors on both sides without touching the column), step up to 22×26×8 at $3,595+. For two HD or dually trucks, choose 24×26×8 at $4,195+. For two trucks plus a workbench or storage area, add length: 20×31×8 or 22×31×8. The 8-foot eave height clears all standard pickups; lifted or HD trucks step up to 9-foot eave.
What size carport for 3 trucks?
The standard 3-truck carport size is 30×31×8 at $5,295+ which fits three full-size pickups side-by-side with comfortable door clearance. For three HD pickups or trucks with camper shells, step up to 30×31×9 or 30×31×10. For three trucks plus a workshop corner, add length: 30×41×8 at $6,695+. For three trucks of mixed sizes (one dually, two single-rear-wheel), the 30-foot width is still the right choice — the width handles the widest truck.
How long should a carport be for a travel trailer?
Add 4-6 feet to your travel trailer's hitch-to-bumper length. A 30-foot travel trailer measures 32-34 feet from hitch to bumper, which needs a 36-40 foot long carport. The extra length provides walking clearance front and back, plus room for the tongue when the trailer is parked. For travel trailers you'll back in and out of the carport, lean toward the longer end of the range — the extra 2 feet makes maneuvering easier.
Can I fit an RV and a car under one carport?
Yes — "RV + car combo" is one of the most-popular carport configurations. A 28×40×14 fits a 25-30 ft travel trailer in the center with a car under one side bay. A 28×60×14 fits a large fifth wheel with a car under one side. A 30×60×16 fits a full-size Class A motorhome plus a daily driver or toad vehicle under flanking bays. The combo configuration costs less than buying two separate carports.
Does a carport need to be bigger than my truck or RV?
Yes. Always add clearance beyond the actual vehicle dimensions. Width: add 3-4 feet of clearance per vehicle for door swing and walk-around. Length: add 4-6 feet for walk-around at front and back. Height: add 18-24 inches above the tallest point of the vehicle (including roof AC, satellite dish, antennas). A carport that's exactly the vehicle's dimensions is unusable — you can't open doors, walk around, or clear the eave without crouching.
How much clearance do I need around a vehicle in a carport?
Standard clearance: 3-4 feet per vehicle on the sides, 4-6 feet front and back, 18-24 inches above the tallest point of the vehicle. For RVs and motorhomes where you'll primarily store rather than actively camp, side clearance can be reduced to 2-3 feet. For buildings where you'll work on the vehicle inside, increase side clearance to 5-6 feet. For trucks with lift kits or HD axles, add 2-4 extra inches of width clearance beyond the standard formula.
Can I order a custom carport size that's not on the standard chart?
Yes. Every carport we build is custom to your exact dimensions. Width adjusts in 2-foot increments (12, 14, 18, 20, 22, 24, 26, 28, 30 feet). Length adjusts in 5-foot increments (any length from 21 feet up to 100+ feet). Eave height adjusts in 1-foot increments (6-16 feet). If none of the standard sizes fit your exact vehicle configuration, request a custom quote with your target dimensions and we'll return pricing within 24-48 hours.
What's the biggest size carport I can order?
Standard custom carports are available up to 30 feet wide, with lengths up to 100 feet, and eave heights up to 16 feet. Beyond those dimensions, builds typically convert to full metal building territory. For the largest RV + car combinations and commercial applications, 30×70×16 at $14,995+ is the standard maximum size for a single carport structure.
Should I measure the carport inside dimension or outside dimension?
Carport width is measured outside-to-outside (frame to frame on the outside). The usable interior width is typically 1-2 feet less than the ordered width because of the frame columns. A 20-foot-wide carport gives you about 18 feet of usable parking width between columns. When sizing for vehicles, use the usable interior width, not the ordered outside dimension. Length is measured outside-to-outside and the usable interior is roughly the same because end columns don't intrude into the parking area.
Can I rent-to-own a custom-size RV or truck carport?
Yes. Rent-to-own is available on every size carport we build — from the 12×21×7 single-truck shelter at $1,595 to a 30×70×16 commercial-grade RV cover at $14,995+. Monthly payments start at $75/month for the smallest truck shelter and $485/month for a Class A motorhome cover. No credit check required. Approval based on initial payment and verified delivery address only. See our complete rent-to-own guide for terms and payment examples.

What Our Customers Are Saying
I'm really happy with the way my building turned out! Due to living in city limits I had to make changes to my original plan but working with Bryan made it easy. He was great to work with!
Bulldog Steel Structures is fantastic. We had a 24'x40' garage built with two 10' garage doors, an entry door, two windows and fully insulated for under $16,000. The whole experience was so easy. Our salesman was Bryan Valadez. Bryan was so helpful and was easily available to answer my questions. Rebekah Aldridge handled all the documents and signing of them. The whole process was great. The building is well constructed and the crew that erected it were courteous and cleaned the worksite afterwords thoroughly. They did an excellent job in a time efficient period. Our experience with Bulldog Steel Structures was just great and we highly recommend them.
I'm in early stages, just put deposit on building. I reviewed about 10 quotes and worked with many vendors in the space to assess. Constance from Bulldog Steel Structures made the experience fabulous and was key in our decision making. It's so refreshing to see a company like this have such outstanding client facing service. We are excited and huge shout out to Constance and the team. Bravo!
I have purchased two structures/buildings from them and have been greatly satisfied. From "idea to implementation" it has gone smoothly. I love the idea of having one single point of contact (Noah) for any questions or concerns. The install crew comes in and gets right to work and the quality is the best I have seen. Highly Recommend!
I worked with Bryan Valadez in putting together my bids for a 2000 SF shop/garage. He was great to work with, very quick to respond and answered all my questions and concerns during several very thorough conversations regarding my project. I recommend you give Bulldog a shot when searching for your next building, their pricing was very good compared with some of the others, and they just seemed to have it very together for their process. Great Job, thanks Bryan. Jason
Showed up on time and excellent quality. Could not be more pleased with the results!
I called and spoke to Bryan. With some back and forth he helped me finalize the design (40x100 foot print). I placed my order and had to wait for my King County building permit to be issued. Once the slab was completed the installation team arrived with all the pieces. They got right to work and the building was completed in 8 days !!! I would highly recommend Bryan and Bulldog to any one :) Many thanks john in the pacific northwest
Great company to do business with. Would recommend them to others.
Great to deal with. Building went up with no problems.
I had a great experience with Bulldog Steel Buildings. The representatives were able to help me move from the online design to an actual building design to meet my goals. They set up the delivery and installation which turned out great. Installation was scheduled quickly after the foundation was done; and the building was completed within 2 days. Pricing was reasonable, and I'm very pleased with my new building.
Bryan was great- honest, helpful, responsive and knowledgeable. I will call him if I ever need another steel building
This company is the real deal. They go over and beyond to satisfy their customers. It is a joy to work with them. They are very knowledgeable and efficient. I looked forward to finishing my project with them.
Humberto was very responsive and it was a pleasure to work with. He went above and beyond to get delivery scheduled as soon as possible for our 30x50 building. Great company to work with.
Hey folks - these people at Bulldog are real. Noah helped me all the way through - extremely patient and knowledgeable. He answers most often and when he doesn't it's easy to get another HUMAN to speak with. I looked at several companies for this project - I settled on the right one. If you wind up doing business with Brian - you're in luck there to. Outstanding work - worthy of trust.
I purchased a 26x32 Garage from Bulldog Steel Structures they had it finished in two days. It looks really nice and the install crew was great. I’m thinking of getting another building and I will definitely contact Bryan Valadez again at Bulldog.
Great experience from start to finish. The sales process was easy and Casey helped me revise my plans several times to get the right building for my needs. Communication was excellent! The build crew was on time, friendly and professional. Beto took the time to understand what cutouts I needed and why I needed them in the sizes planned. Exceptional work. Highly recommend. Thank you!
I would recommend Bulldog Steel Structures highly. They are very professional and accommodating. Want to give special thanks to Randall Hall and also matt preslar. They were very accommodating and helping me fill out paperwork and handling things when a timely basis. The building we were very satisfied with and the installers also were very polite and had things done on a timely basis. Thanks again Randall and Matt you`ve got my five star rating
Bulldog has been great to work with. They explained everything from beginning to end. I live in the mountains of New Mexico and the staff made sure that my garage had the right support needed for this area of the country. I would highly recommend them for anyone building a new carport or gaeage!
Good design tool on their website. Great customer service.
Have had nothing but a positive experience with Bulldog! Bryan was super helpful and still is after our install! He still responds super prompt and helpful. No complaints about our structure, as it looks amazing! Installers did a great job and picked up very nicely after they were done. Highly recommend!!
I have now had my building in place for 3 months and I want to say that the whole team at Bulldog was very helpful throughout the entire process. My salesperson, Matthew, was extremely responsive. He was very helpful with the design phase, where we went back and forth with 3-4 different designs before settling on the perfect one. He always got back to me right away when I had a question. Although the delivery was delayed, understandable with the pandemic, he helped interface with Carolina Carports when I had delivery questions. So far I have no issues with the completed building. No leaks and all the doors are functioning perfectly. I would highly recommend using Bulldog for all your metal building needs.
Frank Rangel was very helpful and respectful. Also very understanding. I was pouring a concrete driveway and trying to put my down payment down. I may of got a little frustrated in the middle of it all. I could see the smile on Frank`s face the whole time! Thank you sir!
This is my second building from bulldog and I`m buying the same building , just different colors. They are great buildings that are strong and economical.
Excellent customer service during my order process, answered all my questions and they were very patient.
The website was very flexible and helped me customize my carport. The Bulldog staff was very prompt and helpful throughout the process.
Put up a RV cover for me on a concrete pad. Turned out great and the guys cleaned up after the work. Very satisfied. Would recommend these people.
I love my “She Shop.” It was amazingly easy. I sent an email, made 2 phones calls and it was done. The installation went even easier. Three guys showed up one day and finished the next. They were polite and cleaned up after themselves. My husband’s friends are all very impressed with the construction and materials used but were amazed at the reasonable price. I could not be more pleased. Thank you
I visited their website and used the 3D estimator and was able to see my building with doors, window placements, colors,and overall look. When you add or change any feature, including size, you can immediately see the result and change in price (if any). You can rotate the structure to see the overall look and framework. Once I placed my order, it was quickly and efficiently handled and the cost was lower than the estimate on the website The installers showed up early one morning and by noon the next day they had completed the structure. Everyone that comes by remarks on how nice it looks. I am very pleased with every aspect from ordering to installation.
