Building a garage isn’t as easy as it first might seem. In fact, the single biggest mistake made is in underestimating the amount of space needed.

Whether you’re building a custom home and looking for garage design ideas, adding on a garage, or buying a house and aren’t sure if your vehicle will fit, this guide will give you a firmer grasp of standard garage size requirements for most vehicles.

Size Matters

A garage is more than a simple shell. It has inner workings above and space to move, work, and store around the sides. Let’s take a quick look at how each dimension of your garage affects its usefulness.


It’s easy to miscalculate the height of a garage. This important dimension goes beyond the height of your car. You must account for door clearance, garage door openers, headroom, overhead lighting, and (if you need it) storage space.

Remember, your vehicle’s antenna may be taller than the roof, so take that into account when choosing the door height.


No matter if you’ll be using a parking aid or not, you’ll want some extra width. You should be able to open the doors on both sides while also having some clearance to get around them. This comes in handy when cleaning the car or if you do your own vehicle maintenance.

Depending on the amount of equipment you plan to store (lawnmowers, tool cabinets, etc.), you may even need to go one vehicle size up.

The most notorious miscalculation is garage depth. You should be able to walk all the way around your car while it’s parked. The space in front of your vehicle is also the most common location for storage and workbenches.

Living Space

Many owners use their garage as extra space to live or work. Detached garages make excellent workspaces, as you’re less likely to wake the kids. Attached garages often double as another room for your friends and family, providing a prime location for a pool table, home gym, or your weekly poker night.

Having an extra bay means space you can dedicate to these functions. Otherwise, you will need to have a much deeper floorplan and keep activities opposite the main door.

Plan Ahead

Your vehicle isn’t a permanent fixture. You may eventually trade in your full size truck for something smaller and more fuel efficient. Likewise, you may need to exchange that small 2-door for a minivan as your family grows.

Finally, think about any older children in your home. If they’re approaching driving age, will they have their own dedicated vehicle? If so, make sure you have space for it when the time comes.

Average Vehicle Dimensions

average car dimensions

Now that we’ve considered what the garage will be used for and how that affects space, let’s start getting into just how much space the average single-vehicle garage requires by looking at common vehicle sizes and the design measurements most often used for those vehicles.

Average car lengths continue to increase, especially in the US. Because vehicles come in many shapes and sizes, below is a breakdown of average vehicle dimensions in various classes including cars, trucks, SUVs, and more.

Important Note About Vehicle Widths: Keep in mind that when you’re trying to determine your optimal garage size, don’t forget to add an additional 5 to 6 feet to the width of a vehicle to account for doors being open on both sides. Sports cars, longer cars, coupes, and heavy duty trucks will typically be wider than economy cars, shorter cars, sedans, and standard pickup trucks.

Compact Cars

  • Examples: Kia Rio, Chevy Cruze, Mazda 3, Ford Focus, Toyota Corolla
  • Average Length: 14 feet and 8 inches
  • Average Width: 5 feet and 10 inches
  • Average Height:  4 feet and 9 inches

Mid-Size Cars

  • Examples: Honda Accord, Audi A4, Mazda 6, Toyota Camry, BMW 3 Series

  • Average Width: 6 feet and 1 inch
  • Average Height:  4 feet and 9 inches

Full-Size Cars

  • Average Length: 16 feet and 8 inches
  • Average Width: 6 feet and 2 inches
  • Average Height:  4 feet and 10 inches

Mid-Size Trucks

  • Examples: Ford Ranger, GMC Canyon, Toyota Tacoma, Nissan Frontier, Chevy Colorado
  • Average Length: 17 feet and 9 inches
  • Average Width: 6 feet and 3 inches
  • Average Height:  5 feet and 10 inches

Full-Size Trucks

  • Examples: Chevy Silverado, Ford F-150, GMC Sierra 1500, Dodge Ram 1500, Toyota Tundra
  • Average Length: 19 feet and 6 inches

  • Average Width: 6 feet and 7 inches
  • Average Height:  5 feet and 9 inches

1-Car Garage Dimensions

Note: All measurements referenced in these garage size diagrams are referring to the interior dimensions. Add 6-7 inches per wall for exterior dimensions.

1 car garage dimensions

For a Car or Crossover SUV

Taking these measurements into account, the most common conservative garage size for a single car will be 20′ long, 12′ wide, and 7′ tall. You can get away with a 8′ by 7′ garage door, but may prefer one that’s 8′ tall for more headroom.

Minimum dimensions for a 1-car garage are: 12 ft. wide x 20 ft. deep

Common garage widths are 12′, 14′, or 16′; while the length most often measures 20′, 22′, or 24′.

Of course, even average garage sizes vary based on usage, and many homeowners prefer the superior headroom of an 8-foot door and higher interior clearance. Remember, the garage door is your ceiling when open, so choose your garage door height accordingly.

On the large size, a single car garage measuring 24′ by 16′ by 8′ will provide space for one foot deep shelves on both sides and 10 to 12 feet of work and living space behind. Additionally, you have room to add one-foot tall suspended storage racks, making this an excellent size for a hybrid car/storage/living space.

For a Truck, SUV, or Minivan

Full-sized trucks and SUVs (and minivans) are much bigger than the average car and require a larger garage. Minivans and SUVs require additional rear-loading clearance so they essentially have the same height as a full-size truck when the rear is open.

Due to their increased size, the minimum comfortable size for a single large vehicle would be 28′ long, 16′ wide (with 9′ by 8′ garage door), and 8′ tall. You’ll want a wider garage door width to avoid losing your mirrors when not perfectly aligned during entry/exit.

2-Car Garage Dimensions

2 car garage dimensions

Things become a little more complicated once you expand to multiple cars. This is primarily due to the choice of a wider 16′ garage door or two 8′, 9′, or 10′ doors. The average lengths tend to remain 20′ to 24′, while the height should be calculated based on the tallest vehicle in your family fleet. Unlike single car garages, you only need clearance for the inside doors of one car at a time.

Minimum dimensions for a 2-car garage are: 22 ft. wide x 20 ft. deep

A fairly common form of multi-car garage, families often use one side for living or storage space when they only have one vehicle. These garages will usually use two 9′ or 10′ doors and may have some form of divider to separate the two spaces aesthetically. Single 16′ doors are more common when two vehicles are being stored.

When calculating the width you’ll need, add the width of your vehicles plus 7′ 6″ minimum to account for door clearance. The average width for a two-car garage will usually be between 22′ and 26′. A larger width not only leaves room for side storage, but also creates more leeway for crooked parking.

3-Car Garage Dimensions

3 car garage dimensions

Three car garages require a minimum of 10′ for car door clearance and may use one double-wide (16′) door and one regular door or three regular doors. In general, common widths for a 3-car garage are 31 to 34 ft. while the common depths are 20 to 24 ft.

Minimum dimensions for a 3-car garage are: 31 ft. wide x 20 ft. deep (unless tandem)

4-Car Garage Dimensions

4 car garage dimensions

A true rarity, four car garages can handle a small fleet of vehicles. These garages may have one or two double-width doors and up to four single doors. Of all the garage sizes, these monsters rely least on the average width of a car, since the occupying vehicles will most likely vary in size.

Minimum dimensions for a 4-car garage are: 40 ft. wide x 20 ft. deep (unless tandem)

Many owners will either assign specific bays to specific vehicles, having wider doors for trucks than cars or have all bays big enough for their largest vehicle. Five car door lengths (or 12′ 6″) should be added to the vehicle widths for a minimum space requirement. A good rule of thumb is to have a width of no less than 40′.

Tandem Garage Dimensions

tandem garage dimensions

This is a special version of a multi-car garage where the two cars are stored in line and not side-by-side. The width and height for tandem garages are the same as a regular garage, while the depth is usually 36 to 40 feet to allow for safer parking or for use as tool area or shop.

Tandem garages may be one to three bays wide with one or more of those bays allowing for tandem parking.

Carports are another matter entirely. These open-plan parking spaces make it easy, as you only need minimum dimensions and don’t have to worry about storage or living space. Base the size of your carport on your vehicle’s clearance requirements using these simple questions.

How Long is a Car in Feet?

Cars (and trucks) range in average length from about 13 to 20 feet. See the Average Vehicle Dimensions section above to get a good idea of the length of your vehicle or simply measure it.

Give yourself a bit of leeway, especially if you don’t plan on adding some form of stop to the rear of the port. As a general rule, carports tend to be between 21′ and 26′ in length.

How Wide is a Car in Feet?

Vehicle widths range from about 6 to 7 feet with the doors closed. See the Average Vehicle Dimensions section above to get a good idea of the width of your vehicle or simply measure it. You will want to factor another 5 feet to have both doors open and give a little extra leeway off-center parking.

As carports tend to be open space, the width for an average car is about 12 feet. You may wish to go up to 16 feet for wider vehicles.

How High Should the Roof be in Feet?

Picking the height for your carport is a lot more lenient than a garage, as there are no doors. Instead, the average carport is about 12 feet tall to allow plenty of clearance and the option of lighting. Some extra large vehicles, such as RVs will need a higher roof.

Single vs Double Carports

As mentioned above, single carport dimensions are fairly basic, but what about double carport dimensions? While the length and height remain the same, the width for a two-car carport will range between 18 to 24 feet on average.

Take into account the widest vehicle you plan to store and base your width off of double that width plus door clearance for the best fit.

  1. Chris, thank you for the information about garages. My one basic question is this, are the dimensions stated as the inside dimensions of the garage? thanks, Dave

    • Good question that I failed to mention in the article. The dimensions would be the interior to make measuring for floor space easier. The outside wall dimension would be about 6-7 inches higher per wall.

  2. Hi Chris,

    Great write up! Thanks! Question you may know the answer to. I’d like to be able to install a lift in the garage to store two cars one on top of the other. What should my ceiling height be?

    Thanks! Greg

    • The minimum height is actually less than what most people think. Obviously it would depend on the vehicles but the general rule of thumb is the height of vehicle #1 + height of vehicle #2 + 1 foot. In some cases, you can get away with a 10 foot ceiling. Ideally (if the garage hasn’t been built yet), it would be closer to 13 to 14 ft.

      Other than the type of vehicles, the minimum ceiling height can also be affected by ramp thickness, overhead door clearance, garage door opener, and lighting.

  3. We want to build a stand alone garage for two full sized pickup trucks plus a golf cart.
    What would the minimum measurements be, allowing for space to move around the vehicles?

    • I’d recommend a 30′ – 32′ wide garage (32′ preferred) and a depth of at least 24′ (26′ preferred depending on length of trucks and the need to place a refrigerator or workbench/storage in front or to walk around the front and back of both trucks. The depth for the golf cart garage can be less than 24′ if need be. For resale value, I’d keep the depth of the golf-cart garage @ a minimum of 20′ so the garage can still be considered a 3-car. Granted, the latter would assume a vehicle access door with a minimum width of 8′ (9′ preferred).

  4. Great article, very helpful. I want to build a garage to store a boat (30 ft with trailer) and 5 cars (largest would be a truck). The space I have available has a lot of length but limited width which is creating my dilemma. Do you think it is better to park the cars end to end (so you would have to parallel park them) vs like they do in a Parking lot more at an angle? I need to be able to get to the boat and pull it out so the cars need to be far enough away to get to it easily (or it could be on the other side in the back). On the other side of the garage (away from the cars), I only need storage space for lawn equipment (including a riding mower) and holiday decorations so there will need be shelves.

    What do you think the ideal dimensions would be to accomplish these goals? Thanks.

  5. The standard garage door width and height can vary by where you live but is usually: 8 feet wide by 7 feet tall, or 9 feet wide by 7 feet tall for a single car garage door. 16 feet by 7 feet for a double garage door.

    • In Tulsa, 9 feet wide and 7 feet high is the most common size for a single garage door and 16 feet wide by 7 feet high for a double garage door. I recommend 18 feet wide for the double doors so you can drive both vehicles straight into the garage without having to park at a slight angle to avoid the doors between the cars from hitting one another. I also recommend 8 foot high doors where the ceiling height will accommodate one – which nowadays is in most new garages. Entry level homes typically cap the height at 7 feet.

  6. Good article, I am building a house with a 2 car side entry garage 25 ft width and 20.8 feet depth. The situation is the builder has to foundation about 15.6 ft from the sidewall. To give more space to turn into the garage easier, I am considering taking 2 to 4 feet from the garage’s depth. Doing this, would the garage be too small to hold the Lexus ES350 cars?

  7. I’m building a house and will have a 4 stall attached side entry garage so the house will
    be an “L” shape. Would it make more sense to have 2 single doors and a double as opposed to 4 singles? I will also be making the garages drive thru compatible with doors on both sides so I can pull vehicles into the backyard. I have a 4 door longbox pickup so about as long a vehicle as you can get. What would my dimensions be thanks.

  8. Very useful comments.
    For stacking cars (mainly sports cars – Porsche etc, how high do you recommend the ceiling to be on a 2 car garage?

  9. Hi Eric and Chris, I see articles showing the dimensions of vehicles and room to park them, BUT fail to mention any space needed to get in and out of vehicles. The door width should also be taken into account for ample space. I hate to squeeze into a car with all my stuff (not to mention kids) while worrying about banging a door against my other vehicle. I looked and found that openings for trucks or cars are different depending on the make/model, but “worry free” opening is typically 3 feet. So a vehicle width plus 3 feet on both sides (6 total) for each door to open is quite a lot to take into account.
    Hope this gets you thinking too!

    • Yes, I absolutely agree. I made sure to include a note to include on average another 5-6 feet to the vehicle width. Some vehicles need more. Add garage storage racks along the walls and it’s even more. I think this is why it’s normal for those with a 2-car garage to simply park a single vehicle in the middle.

      For those looking to build, I always suggest going bigger than you think you’ll need. I can’t think of anyone who has had a home built say that their garage is too large but most will tell you they wish they made in larger.

  10. I am interested in adding a one car garage to the existing two car garage. I would like to connect them inside with a door. The garage would be used for storage (Xmas & etc), a small workshop area, and a gardening storage area. Instead of the normal entrance door, I would install a window. The overhead door would face the backyard. I could substitute that door with double doors if possible. Do you have any idea what this would cost to build?

  11. Thank you for the great article.
    Currently I have a 1936 20×20 detached that fits one small SUV due to the other storage stuff. I am taking down the 1936 and debating between two new options due to the house to property line restrictions.
    1.) Attach a 20 wide x 42 deep (exterior dimensions) tandem like your picture for three cars, the fourth spot is for a much needed mudroom and half bath. This option gets us a bigger back yard on a small 0.3 acre lot. I am very considered about the 20 wide not being enough for two large vehicles and opening the doors. The city also requires two separate doors on attach garages which then can only be 8′ wide due to the 20′.
    2.) A new detached with small apartment above. The city will only allow me 24wx28d or 26×26, nothing larger. Since it is detached the city will let me do one 16′-18′ door. I would then need make a 10×16 addition to the house for the mudroom and half bath. I miss out on the doubling the size of my backyard.
    What would you recommend?

  12. Large Two car garage ( F150 truck/ Chevy suburban ) with good size side storage room.

    What size should I start with. Needs to be roomy. Building a free standing garage and don’t want to build and then wish I had made it larger.

  13. Hi there,
    I’m looking at building a garage with a guest apartment above it. I’m thinking a footprint of 60’(w) x 48’(d)
    This would include space for 6 cars in tandem, (3 people winter & summer cars) and a 45’ RV. With a flight of stairs on the side (inside) to access the 2 bedroom apartment upstairs.
    My question is, do you think my measurements are too big, or is it good enough?
    The building will be a separate garage/guest house. I do not need room for storage And my “toys” have their own storage space.

    • To me it sounds like a good amount of space (most people would kill for a garage like that, haha.) if you have a separate garage/storage area for other stuff. Only question is if you’re planning on having a separate area for a tools, workbench, tire/wheel storage, auto detailing products, etc. Also, do you plan on putting in a drain for car washes (if you live in a cooler climate). If so, you’ll want a bit of extra space there.
