Is a 16 ft garage door big enough for two cars?

[OBella]

A standard 16 ft wide garage door is the minimum size for two cars, but it can be tight depending on your vehicle models and lifestyle. While it provides enough width to park two mid-sized sedans side-by-side, the clearance for entering, exiting, and storing additional items is limited. For comfortable daily use with modern vehicles, a larger 18 ft door is increasingly recommended.

The core issue is vehicle width. The average width of a mid-size sedan like a Toyota Camry is about 6.1 ft. Two of these would occupy 12.2 ft, leaving roughly 1.9 ft of clearance per side when centered. This space is consumed by mirrors and door swing. Modern full-size SUVs and trucks, such as a Ford F-150 (6.9 ft wide) or a Chevrolet Tahoe (6.8 ft wide), make a 16 ft opening feel cramped. Parking two larger vehicles often requires careful alignment and necessitates folding in mirrors.

Vehicle Type	Avg. Width (ft)	Scenario in 16 ft Door	Key Consideration
Two Mid-Size Sedans	~6.1 ft each	Possible, but tight.	Door opening clearance is minimal; careful parking needed.
One SUV + One Sedan	~6.8 ft + ~6.1 ft	Very tight.	Drivers may need to exit before parking or use single-file parking.
Two Full-Size Trucks/SUVs	~6.9 ft each	Impractical for daily use.	Vehicles will likely scrape mirrors; risk of door dings is high.

Practical experience shows that the primary challenge isn't just parking but maneuvering within the garage. Stepping out of the car becomes a squeeze, making it difficult to unload groceries or children. There's also little to no room for shelves, storage cabinets, bicycles, or lawn equipment along the walls without impeding the doors. Industry data from door manufacturers like Clopay and Haas Door indicates a clear trend toward 16 ft doors being specified for compact two-car garages, while 18 ft doors are becoming the new standard for comfortable two-car parking.

Construction and cost factors support considering a wider door. The rough opening for a 16 ft door is about 16' 1", requiring a garage front wall of at least 20 ft. Upgrading to an 18 ft door (requiring ~18'1" rough opening) often doesn't significantly increase the overall build cost of a new garage but substantially improves long-term usability and home resale value. For an existing garage, widening the opening is a major structural retrofit.

In summary, a 16 ft garage door works for two smaller cars with careful use, but it represents the lower bound of functionality. For a future-proof garage that accommodates a variety of vehicle sizes and provides practical space for storage and movement, investing in an 18 ft wide door is a prudent and highly recommended decision.

As a homeowner with a 16 ft door and a sedan plus an SUV, I can tell you it’s a daily puzzle. We make it work, but it’s not comfortable. My wife has to pull in first, perfectly centered, then I edge my SUV in behind hers. Forget about opening the doors all the way—we do the “garage shuffle,” turning sideways to get out. The kids’ bikes had to go to the shed because there was zero wall space left. If I were building again, I’d absolutely go for 18 feet. The extra two feet would feel like a luxury.

Let’s break down the math simply. My old garage had a 16 ft door. My Honda Accord is about 6 feet wide, and my neighbor’s similar car is the same. That’s 12 feet of car. The door gives us 16 feet, so you’d think 4 feet to spare. But that space isn’t just on the sides; it’s total width. With both cars centered, you get about 2 feet on each side. Side mirrors stick out maybe another half foot. So now you have 1.5 feet. Try opening your car door in that space—you can’t. You get out in stages. It’s functional, but it’s not enjoyable. For a hassle-free experience, especially with any larger vehicle, more width is the first thing I’d change.

I run a property management company, and garage size is a frequent topic with buyers and tenants. The feedback is consistent: people who have 16 ft doors for two cars always mention the tight fit. Those with 18 ft doors never complain about width. It’s a clear differentiator. Modern cars are simply wider than they were 20 years ago when 16 ft was more acceptable. We now advise developers and clients that for new constructions or major renovations, an 18 ft door is a standard upgrade that significantly boosts satisfaction and practicality. It’s a relatively small upfront cost that eliminates a major daily irritation.

Think beyond just the cars. When we designed our home, we opted for the standard 16 ft wide garage door. The reality hit quickly. Yes, our two cars fit inside, but the garage became purely a parking closet. There was no room for the trash cans, the lawn mower, or my workbench. Every inch was claimed by the vehicles. We had to store everything else in the basement or an external shed, which is inconvenient. The psychological effect is real—the garage feels cramped and stressful to enter. In contrast, my brother’s garage with an 18 ft door has space for cars and a neatly organized wall of storage and a freezer. That extra two feet of door width transforms the entire functionality of the space from a bare minimum parking zone into a true utility area. The decision isn’t just about car widths; it’s about how you want to use the entire footprint of your garage.
