A standard two-car garage in the U.S. is typically 20 feet wide. However, this is a minimum and often insufficient for modern vehicles. The comfortable and more common width for a new build is between 22 and 24 feet. This extra space is crucial for opening car doors without dinging the vehicle or wall next to you.
The 20-foot standard comes from an era of smaller cars. Today's full-size SUVs and trucks, like a Chevrolet Suburban or Ford F-150, can be over 80 inches (nearly 7 feet) wide each. Parking two such vehicles in a 20-foot wide garage leaves less than 6 inches of clearance between them, making it a tight, impractical squeeze. The ideal width is 24 feet, which provides a 3-foot buffer between vehicles and on the sides, allowing for easy entry/exit and some storage space along the walls.
When planning, also consider the garage door opening. A single 16-foot wide door is standard, but two separate 8 or 9-foot doors offer more flexibility. Don't forget about depth; a minimum of 20 feet is needed, but 22-24 feet is better for trucks with long beds. Always measure the exact dimensions of your vehicles, including side mirrors, to ensure a proper fit.
| Vehicle Type | Example Model | Approximate Width (with mirrors) | Recommended Clearance per Side |
|---|---|---|---|
| Mid-size Sedan | Toyota Camry | 6.2 ft (74 inches) | 1.5 - 2 ft |
| Full-size SUV | Chevrolet Tahoe | 6.9 ft (81 inches) | 2 - 3 ft |
| Full-size Truck | Ford F-150 | 6.9 ft (83 inches) | 2 - 3 ft |
| Minivan | Honda Odyssey | 6.7 ft (79 inches) | 2 ft |
| Compact SUV | Honda CR-V | 6.0 ft (73 inches) | 1.5 ft |

From my experience, calling it a "two-car" garage is often optimistic. The old 20-foot width is a joke if you have anything bigger than a couple of small sedans. You'll be playing a game of Twister every time you get out. For a truly functional space where you can actually open your doors, aim for 24 feet wide. It's the difference between a cramped parking spot and a usable part of your home.

Think beyond just squeezing the cars in. The standard is around 20 feet, but you need to account for the garage door tracks, which take up interior space, and you'll want room for shelves or a workbench. If you ever plan to sell, a wider garage (22-24 feet) is a strong selling point. It shows the home was built with modern needs in mind. Always prioritize function over the bare minimum.

I learned this the hard way. Our "standard" two-car garage is 20 feet wide. With my wife's SUV and my truck, it's a nightmare. We have to park perfectly straight and carefully slide out. If I were building new, I wouldn't go less than 22 feet, and 24 would be ideal. That extra few feet makes all the difference for daily convenience and prevents expensive door dings on your cars. It's a small cost upfront for long-term peace of mind.

The building code minimum is often 20 feet, but that's just a starting point. You need to consider the actual clear width between the inner walls, which might be less. For comfortable use, the general rule of thumb is to add the width of both vehicles and then add at least 4 to 6 feet for walking and door-opening space. For example, two 6.5-foot wide cars need a garage at least 17 feet wide, plus 4-6 feet, so 21-23 feet minimum. Always measure your specific vehicles.
