how wide should a 2 car garage be

[VivianFitz]

A standard two-car garage should be at least 20 feet wide. However, for comfortable, everyday use with modern-sized vehicles, a width of 22 to 24 feet is the recommended minimum. This provides essential clearance for opening car doors without dinging the vehicle or wall next to it. The absolute minimum of 20 feet, often found in older homes, is functionally too narrow for most SUVs and trucks.

The International Residential Code (IRC) sets the minimum interior dimension for a two-car garage at 20' x 20'. This standard is based on the average width of two cars parked side-by-side, but it doesn't account for the space needed for people to get in and out easily. Most new construction now trends toward 22' x 22' or even 24' x 24' to accommodate wider vehicles and provide storage space.

Consider the actual dimensions of your vehicles. A typical midsize sedan is about 6 feet wide, while a full-size SUV or pickup truck can easily exceed 6.5 feet. Parking two 6.5-foot-wide trucks in a 20-foot garage leaves only 7 feet of total space between them and the walls—that's just 3.5 feet per side, which is a very tight squeeze.

Here’s a breakdown of common garage widths and their practicality:

Garage Interior Width	Practical Outcome & Vehicle Compatibility
20 feet	Absolute minimum. Tight for most modern vehicles. Difficult to open doors fully. Best for compact cars only.
22 feet	Good standard. Comfortable for two midsize sedans or crossovers. Allows for manageable door opening.
24 feet	Recommended ideal. Comfortable for larger vehicles like SUVs and trucks. Provides about 1-2 feet of extra wall space for storage or a workbench.
26+ feet	Luxury/Workshop size. Excellent for large trucks with extra cargo space. Ideal if you want significant additional storage or a dedicated workshop area.

Beyond car size, factor in your storage needs. Do you need space for trash cans, bicycles, or lawn equipment along the walls? A wider garage future-proofs your investment, making it more functional and potentially increasing your home's resale value. When in doubt, always opt for the wider option.

From my own experience, 20 feet is a nightmare. We have a sedan and a midsize SUV. I have to park perfectly centered and slide out of the car like a contortionist to avoid hitting the other vehicle. If you can possibly build it wider, do it. Even an extra two feet makes a world of difference for actually using the space without constant stress. It’s worth the extra cost.

Think about what you're actually parking. Look up the widths of your specific car models and add them together. Then, add at least three feet total—more if you have kids who'll fling doors open. That's your realistic minimum. Don't just rely on the builder's standard; they often use the bare minimum code. Your daily convenience is worth specifying a larger size during the planning phase.
