A standard two-car garage door is typically 16 feet wide. However, the most common and recommended size is actually 16 feet wide by 7 feet high. This width provides comfortable clearance for two average-sized sedans, with each bay being roughly 8 to 9 feet wide. It's crucial to measure your garage's rough opening—the framed space where the door is installed—to confirm the exact size needed.
The width isn't arbitrary; it's designed to accommodate most vehicles. For example, a popular midsize SUV like a CR-V is about 6.3 feet wide. A 16-foot door gives each vehicle over a foot of clearance on either side, making entry and exit much safer and reducing the risk of door dings. If you own larger trucks or SUVs, like a Ford F-150 (approx. 6.8 feet wide) or a Chevrolet Suburban (approx. 6.9 feet wide), you might want to consider an 18-foot wide door. This extra space is a significant quality-of-life upgrade, especially if you also need room to walk around the vehicles or store items along the walls.
Before purchasing a new door, always measure the width and height of the rough opening. Also, consider the door style; sectional doors are the most common, but some styles may have different space requirements. Local building codes can also dictate minimum sizes, so it's wise to check those regulations.
| Vehicle Type | Average Width (feet) | Recommended Minimum Door Width for Two Vehicles (feet) |
|---|---|---|
| Compact Car (e.g., Honda Civic) | 5.9' | 16' |
| Midsize SUV (e.g., Toyota RAV4) | 6.2' | 16' |
| Full-Size Sedan (e.g., Chrysler 300) | 6.3' | 16' |
| Full-Size Truck (e.g., Ram 1500) | 6.9' | 18' |
| Large SUV (e.g., Chevrolet Tahoe) | 7.0' | 18' |

From my own experience, 16 feet is the standard, but it can feel tight with two bigger vehicles in there. When we upgraded my wife's sedan to a minivan, suddenly our 16-foot door felt cramped. We were always carefully squeezing out to avoid hitting the other car or the wall. If you're a new door or building, I'd seriously suggest looking at an 18-foot width. The extra two feet make a world of difference for daily use and peace of mind.

Think about what you're parking now and what you might own in five years. A 16-foot door works for standard cars, but the trend is toward wider trucks and SUVs. An 18-foot door is a more future-proof investment. It not only makes parking easier but also provides valuable space for storage or a workbench along the walls. Always measure your garage's opening precisely before you order anything.

As a contractor, I always ask homeowners about their vehicles before we finalize garage plans. The math is simple: take the width of your widest vehicle, double it, and add at least two feet for comfortable clearance. For two trucks, that easily pushes you into 18-foot door territory. Don't forget to check the height, especially if you have a roof rack or are thinking about a lift kit. Proper prevents expensive changes later.

The standard is 16 feet wide, but "standard" might not be best for you. My dad's old pickup and my sister's SUV barely fit through our 16-foot door, and it was a constant source of stress. We measured and found we could fit an 18-foot door with a minor adjustment. The installer handled it. The cost was a bit more, but the convenience is worth every penny. No more guessing if you can open the door all the way. Measure your cars and your space to be sure.
