● Quick Answer
Standard carport sizes range from 12 x 20 feet (single compact car) to 24 x 36 feet (three vehicles with workshop space). The most common sizes are:
- 1-car carport: 12 x 20 or 12 x 24
- 2-car carport: 18 x 20, 20 x 20, or 20 x 24
- 3-car carport: 24 x 24 or 24 x 30
- RV carport: 14 x 36 or 18 x 40 with 13-14 ft height
The right size depends on 3 factors: number of vehicles, their height (lifted trucks and RVs need taller carports), and whether you need extra space for storage, workshop, or opening doors fully.
What Are the Standard Carport Sizes in 2026?
Standard metal carport sizes in 2026 are built around three variables: width (how many vehicles side by side), length (vehicle length plus walking space), and height (vehicle height plus clearance). The chart below shows every standard size that most manufacturers produce, grouped by what they fit.
| Size (W x L) | Vehicle Capacity | Height Range | Best For |
|---|---|---|---|
| 12 x 20 ft | 1 compact car | 6 - 9 ft | Compact sedan, hatchback, small SUV |
| 12 x 24 ft | 1 standard sedan | 6 - 9 ft | Full-size sedan with trunk clearance |
| 12 x 26 ft | 1 car + small storage | 6 - 9 ft | Sedan + bicycles, lawn tools |
| 14 x 24 ft | 1 pickup or SUV | 7 - 10 ft | Standard pickup, full-size SUV |
| 14 x 26 ft | 1 truck + storage | 7 - 10 ft | Pickup + lawn equipment or workbench |
| 16 x 24 ft | 1 larger truck or dually | 8 - 12 ft | Lifted truck, dually, larger SUV |
| 18 x 20 ft | 2 compact vehicles | 7 - 10 ft | Tight 2-car for compact vehicles only |
| 18 x 26 ft | 2 vehicles + walking space | 7 - 10 ft | 2 cars with room to open doors |
| 20 x 20 ft | 2 standard vehicles | 7 - 10 ft | Standard 2-car (most popular size) |
| 20 x 24 ft | 2 vehicles + storage | 7 - 12 ft | 2 cars with workspace along back wall |
| 22 x 24 ft | 2 pickup trucks | 8 - 12 ft | 2 full-size trucks side by side |
| 24 x 24 ft | 2 trucks + storage | 8 - 12 ft | 2 full-size trucks + walking lanes |
| 24 x 26 ft | 3 compact vehicles | 7 - 10 ft | Tight 3-car for compact cars |
| 24 x 30 ft | 3 standard vehicles | 8 - 12 ft | Standard 3-car (most common 3-vehicle size) |
| 24 x 36 ft | 3 vehicles + workshop | 8 - 14 ft | 3 cars + room for workbench, tools, storage |
| 12 x 30 ft | Small RV or boat | 10 - 12 ft | Class B RV, small travel trailer, 20-ft boat |
| 14 x 36 ft | Mid-size RV or standard boat | 12 - 14 ft | Class C RV, 25-ft boat |
| 18 x 40 ft | Large RV or 5th wheel | 14 - 16 ft | Class A RV, 5th wheel, larger boat |
| 20 x 50 ft | Full-size RV + storage | 14 - 16 ft | Full RV with extra side storage |
Three things to notice about this chart: width grows faster than length (because adding a vehicle adds width, not length), height has a wide range even within one size (because a 12 x 24 carport can be built at 6 ft for a sports car or 10 ft for a lifted truck), and the gap between 1-car and 2-car is bigger than the gap between 2-car and 3-car (because the first vehicle sets the width baseline).
What Is the Standard Size of a 1-Car Carport?
The standard size for a 1-car carport is 12 x 20 feet with 6 to 9 ft of height. This fits a compact sedan, hatchback, or small SUV with enough space to open doors and walk around the vehicle. For a larger sedan, pickup, or SUV, step up to 12 x 24 or 14 x 24.
1-Car Carport Size Options at a Glance
| Size | What It Fits | Side Clearance | Length Clearance |
|---|---|---|---|
| 12 x 20 ft | Compact car up to 16 ft long | ~3 ft each side | ~2 ft front and back |
| 12 x 24 ft | Full-size sedan or small SUV | ~3 ft each side | ~4 ft front and back |
| 12 x 26 ft | Sedan + storage shelf at back | ~3 ft each side | ~6 ft at back for storage |
| 14 x 24 ft | Pickup truck or full-size SUV | ~4 ft each side | ~4 ft front and back |
| 14 x 26 ft | Pickup + storage or workbench | ~4 ft each side | ~6 ft at back for workspace |
| 16 x 24 ft | Lifted truck or dually | ~5 ft each side | ~4 ft front and back |
The 12 ft width works for almost any single car but gets tight if you open both doors at once. If you ever carry child seats, bulky equipment, or passengers who need the door fully open, step up to 14 ft wide — the extra 2 feet transforms how usable the carport feels.
What Is the Standard Size of a 2-Car Carport?
The standard size for a 2-car carport is 20 x 20 feet with 7 to 10 ft of height. This fits two standard vehicles side by side with enough space to open doors on both. For two full-size trucks or two SUVs, step up to 22 x 24 or 24 x 24. For two compact cars with no need for walking space, 18 x 20 works.
2-Car Carport Size Options at a Glance
| Size | What It Fits | Comfort Level |
|---|---|---|
| 18 x 20 ft | 2 compact cars only | Tight — vehicles park bumper to bumper width-wise |
| 18 x 26 ft | 2 cars with walking room | Workable — length gives room to walk around |
| 20 x 20 ft | 2 standard sedans or small SUVs | Standard — the most common 2-car size for a reason |
| 20 x 24 ft | 2 standard vehicles + storage | Comfortable — room for lawn equipment at back |
| 22 x 24 ft | 2 pickup trucks | Comfortable — fits full-size trucks with doors open |
| 24 x 24 ft | 2 full-size trucks + walking lanes | Spacious — includes walking space between vehicles |
| 24 x 26 ft | 2 trucks + workbench | Spacious — workshop configuration |
Why 20 x 20 is the default:
A 20 ft width gives each vehicle a 10 ft bay. A standard pickup is 6.5 ft wide, which leaves about 1.75 ft on each side for door-opening space. For two sedans (both about 6 ft wide), that is 2 ft of clearance per side, which is enough for most families. If you drive full-size trucks, go wider.
What Is the Standard Size of a 3-Car Carport?
The standard size for a 3-car carport is 24 x 30 feet with 8 to 12 ft of height. This fits three standard vehicles side by side. For a tighter fit with three compact cars only, 24 x 26 works. For three vehicles plus workshop space along the back wall, step up to 24 x 36.
3-Car Carport Size Options at a Glance
| Size | What It Fits | Width Per Vehicle |
|---|---|---|
| 24 x 26 ft | 3 compact cars (sedans only) | ~8 ft each — tight |
| 24 x 30 ft | 3 standard vehicles | ~8 ft each with 4 ft extra depth |
| 24 x 36 ft | 3 vehicles + 6 ft workshop depth | ~8 ft each + workshop zone |
| 28 x 30 ft | 3 pickups or SUVs | ~9.3 ft each — comfortable |
| 28 x 36 ft | 3 trucks + workshop space | ~9.3 ft each + workshop zone |
| 30 x 30 ft | 3 full-size trucks with walking lanes | ~10 ft each — spacious |
A 24 ft width is the smallest practical 3-car width because it gives each vehicle a 7.5 ft to 8 ft bay. That is enough for sedans and compact SUVs. If any of the three vehicles is a full-size pickup, dually, or large SUV, 24 ft starts to feel cramped. The 28 ft and 30 ft widths cost more but add real usability for the next 20 years of the carport’s life.
What Are the Standard RV and Boat Carport Sizes?
Standard RV Covers and boat carports range from 12 x 30 feet (small travel trailer or 20-ft boat) up to 20 x 50 feet (full-size Class A RV with extra side storage). Height matters more here than for vehicle carports — most RVs need 12 to 14 ft of clearance, and some Class A rigs with rooftop air conditioners need 15 ft.
RV and Boat Carport Size Options
| Size | What It Fits | Recommended Height |
|---|---|---|
| 12 x 30 ft | Class B RV, 20-ft boat on trailer, small travel trailer | 10 - 12 ft |
| 14 x 36 ft | Class C RV (24-32 ft), 25-ft boat with trailer tongue | 12 - 14 ft |
| 14 x 40 ft | Class C RV + extra length for slide-outs or awning | 12 - 14 ft |
| 16 x 40 ft | 5th wheel trailer or large travel trailer | 13 - 15 ft |
| 18 x 40 ft | Class A RV (32-45 ft) or 5th wheel + walking space | 14 - 16 ft |
| 20 x 40 ft | Class A RV + storage on side | 14 - 16 ft |
| 20 x 50 ft | Full-size Class A RV + boat on trailer or vehicle | 14 - 16 ft |
RV Sizing by Class
| RV Class | Typical Length | Typical Height | Minimum Carport |
|---|---|---|---|
| Class B (camper van) | 17 - 23 ft | 9 - 10 ft | 12 x 30 at 11 ft tall |
| Class C (small to mid) | 24 - 32 ft | 11 - 12 ft | 14 x 36 at 13 ft tall |
| Class A (full-size motorhome) | 26 - 45 ft | 12 - 13.5 ft | 18 x 50 at 15 ft tall |
| Travel trailer (small) | 15 - 25 ft | 9 - 10 ft | 12 x 30 at 11 ft tall |
| Travel trailer (large) | 26 - 40 ft | 10 - 11 ft | 14 x 44 at 12 ft tall |
| 5th wheel | 25 - 42 ft | 12 - 13 ft | 16 x 44 at 14 ft tall |
| Toy hauler | 30 - 44 ft | 12 - 13 ft | 16 x 48 at 14 ft tall |
Important for RV owners:
Measure your RV with the rooftop air conditioner, satellite dish, and any roof-mounted solar panels included. These add 6 to 18 inches of height that is easy to forget. Also add at least 6 inches of overhead clearance so the roof doesn’t scrape when you pull in on a hot day — thermal expansion of the carport changes clearance by up to an inch across the seasons.
How Tall Should a Standard Carport Be?
Standard carport height ranges from 6 ft (low-profile for a single sports car) to 16 ft (full-size Class A RV with air conditioner). The right height for your carport depends on your tallest vehicle plus clearance for opening doors, hoods, and any roof-mounted equipment.
Recommended Carport Height by Vehicle Type
| Vehicle Type | Vehicle Height | Recommended Carport Height |
|---|---|---|
| Sports car / low sedan | 4.5 - 5 ft | 6 - 7 ft |
| Standard sedan | 4.5 - 5 ft | 7 - 8 ft |
| SUV / crossover | 5.5 - 6 ft | 8 - 9 ft |
| Standard pickup truck | 6 - 6.5 ft | 8 - 9 ft |
| Full-size SUV (Suburban, Expedition) | 6 - 6.5 ft | 9 - 10 ft |
| Lifted truck (3-inch lift) | 7 - 7.5 ft | 9 - 10 ft |
| Dually pickup | 6.5 - 7 ft | 9 - 10 ft |
| Minivan | 5.5 - 6 ft | 8 - 9 ft |
| Cargo van (Transit, Sprinter) | 7 - 10 ft | 11 - 12 ft |
| Class B RV | 9 - 10 ft | 11 - 12 ft |
| Class C RV | 11 - 12 ft | 13 - 14 ft |
| Class A RV | 12 - 13.5 ft | 14 - 16 ft |
| Boat on trailer (bass boat) | 7 - 8 ft | 9 - 10 ft |
| Boat on trailer (center console with T-top) | 10 - 11 ft | 12 - 13 ft |
Why the Extra Height Matters
Carport height is measured from the ground to the lowest point of the roof structure. The usable clearance under the eaves is often 6 to 12 inches lower than the center peak. Your vehicle has to fit under the eaves, not the peak. Three common clearance mistakes:
- Forgetting the roof rack, cargo box, or kayak on top of the vehicle (adds 6 to 24 inches)
- Forgetting RV antenna, air conditioner, or solar panel (adds 6 to 18 inches)
- Forgetting that lifted trucks and SUVs grow 2 to 6 inches taller with the lift kit
When in doubt, add 12 inches to the vehicle’s measured height. A carport that is 6 inches too tall is invisible; a carport that is 6 inches too short is a disaster the first time you forget and try to drive in.

How Do You Choose the Right Carport Size for Your Vehicle?
Choosing the right carport size is a 4-step process: measure your vehicles, add clearance for doors and walking, factor in any storage or workshop needs, and plan for one future upgrade. Most owners who are unhappy with their carport underestimated at least one of these.
Step 1: Measure Your Vehicle Correctly
Measure the longest vehicle you will park under the carport, then measure the widest. Those two numbers set your baseline. Add roof racks, cargo boxes, and tow balls to the measurement — they count.
Step 2: Add Clearance for Everyday Use
| Clearance For | Add to Each Side | Add to Length |
|---|---|---|
| Walking around the vehicle | 3 - 4 ft each side | 2 - 3 ft at front/back |
| Opening car doors fully | 3 ft each side (door swing) | — |
| Opening truck tailgate | — | 4 ft at back |
| Opening SUV rear hatch upward | — | 6 ft at back + height clearance |
| Opening RV slide-outs | 3 - 4 ft on one side | — |
| Workshop or workbench along back wall | — | 6 - 8 ft at back |
| Storing lawn equipment at back | — | 4 - 6 ft at back |
Step 3: Factor in Storage and Workshop Needs
If you will store anything else under the carport — lawn mower, bicycles, kayaks, workbench, tools — plan the extra square footage now. Adding storage space during the initial build is far cheaper than adding a lean-to or second structure later.
Step 4: Plan for One Future Upgrade
The most common Semi-Truck Carports regret is undersizing. A family with one car buys a 1-car carport, then 3 years later gets a second vehicle and has nowhere to park it. If you can afford one size up from your current need, buy it. The incremental cost of 2 to 4 extra feet of width or length is small compared to building a second structure later.
Frequently Asked Questions
What is the most common carport size?
The most common carport size is 20 x 20 feet, which fits two standard vehicles side by side. For single-vehicle carports, 12 x 20 is the most common. For three-vehicle carports, 24 x 30 is the most common. These three sizes account for roughly 70% of all standard metal carports sold in 2026.
What size carport do I need for one car?
For one standard sedan, 12 x 20 feet is enough. For a pickup truck or full-size SUV, 14 x 24 is the right size. For a lifted truck or dually, go to 16 x 24 with at least 10 ft of height. Add 2 ft to the width if you need to open both doors fully at the same time.
What size carport do I need for two cars?
For two standard vehicles, 20 x 20 feet is the standard. For two pickup trucks or two SUVs, 22 x 24 is more comfortable. For two cars plus storage or walking space, go to 20 x 24 or 24 x 24. An 18 x 20 works only for two compact cars with no need for door-opening space between them.
What size carport do I need for a truck?
For a standard pickup truck, 14 x 24 feet with 9 ft of height works. For a lifted truck, dually, or long-bed pickup, go to 16 x 26 with at least 10 ft of height. If you tow a trailer and want to park both under cover, add 12 to 20 ft of length depending on trailer size.
What size carport do I need for an RV?
For a Class B RV or camper van, 12 x 30 with 11 ft of height works. For a Class C RV (24-32 ft), use 14 x 36 with 13 ft of height. For a Class A RV, go to 18 x 50 with 15 ft of height. Always add 12 inches to your RV’s measured height to account for air conditioners, antennas, and solar panels.
How tall should a carport be?
Standard carport height is 7 to 9 ft for sedans and SUVs, 9 to 10 ft for pickup trucks, 10 to 12 ft for cargo vans and lifted trucks, 12 to 14 ft for mid-size RVs and boats with T-tops, and 14 to 16 ft for full-size Class A RVs. Add 12 inches to your vehicle’s measured height to account for roof-mounted equipment and thermal expansion of the carport frame.
How much space do I need between my vehicle and the carport posts?
Plan on 2 to 3 ft of clearance between the widest point of your vehicle (including open doors) and the posts. For a sedan with 6 ft of width and 3 ft of door swing per side, you need at least 12 ft of interior width. For a pickup with 6.5 ft of width and the same door swing, you need at least 12.5 ft. If children or elderly passengers use the vehicle, add 1 ft to each side for easier access.
Should I buy a bigger carport than I need right now?
Yes, if you can afford one size up. The most common carport regret is undersizing. Adding 2 to 4 ft of width or length during the initial build costs a small fraction of what adding a second structure or lean-to costs later. A 2-car owner who thinks they might someday get a third vehicle, or a boat, should buy a 3-car size now. The future-proofing pays off within 5 years for most families.
The Bottom Line
Standard carport sizes exist because most owners fit the same patterns: one commuter car, two family vehicles, three vehicles with a growing family, or one RV with extra height. The chart in this guide covers 95% of all residential carport needs. If your situation falls outside those patterns — three oversized trucks, a Class A RV plus two boats, a workshop that doubles as a parking area — a custom size is almost always a better long-term investment than cramming into the nearest standard size.
The three rules that matter most: measure your tallest and widest vehicle (including roof equipment), add realistic clearance for doors and walking, and buy one size up if you can afford it. A carport is a 25 to 30 year investment. The extra 2 ft of width you buy today saves a second structure 10 years from now.

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!
Corey Evans
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.
Mattie Roberts
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!
Max Escuder
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!
Ron Barnes
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
Jason Ford
Showed up on time and excellent quality. Could not be more pleased with the results!
Drew Hood
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
John Marcus
Great company to do business with. Would recommend them to others.
Webster Smith
Great to deal with. Building went up with no problems.
Florida Chapter POCI
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.
David Grover
Bryan was great- honest, helpful, responsive and knowledgeable. I will call him if I ever need another steel building
Allan Brown
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.
David Thomas
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.
Kelly Heckel
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.
Randall Drew
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.
Kris Phillips
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!
Damon Trim
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
Shirley M.
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!
Bruce J.
Good design tool on their website. Great customer service.
John S.
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!!
Kristie S.
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.
Mike W.
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!
Jason M.
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.
Parke H.
Excellent customer service during my order process, answered all my questions and they were very patient.
Jack D.
The website was very flexible and helped me customize my carport. The Bulldog staff was very prompt and helpful throughout the process.
Dale & Karen W.
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.
Dan and Linda I.
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
DTheressa J.
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.
