Standard Garage Door Sizes
Garage doors are manufactured in standard widths and heights that fit the vast majority of residential garages. Knowing your exact door size is essential when ordering a replacement door, springs, or an opener with the correct horsepower rating. Here are the standard sizes used across Tucson and the rest of the U.S.
Single-Car Garage Doors
The most common single-car garage door sizes are:
- 8 x 7 feet (96″ x 84″): The standard for older homes and compact garages. Fits most sedans and small SUVs.
- 9 x 7 feet (108″ x 84″): The current standard for new construction. Provides extra clearance for larger vehicles, truck mirrors, and door opening.
- 10 x 7 feet (120″ x 84″): Common in luxury homes and garages designed for larger trucks or workshop access.
- 9 x 8 feet (108″ x 96″): The 8-foot height is increasingly popular for taller trucks, SUVs, and vehicles with roof racks.
Double-Car Garage Doors
- 16 x 7 feet (192″ x 84″): The most common double-car garage door in American homes, including the majority of Tucson homes built from the 1980s onward.
- 16 x 8 feet (192″ x 96″): Gaining popularity in new construction to accommodate taller vehicles.
- 18 x 7 feet (216″ x 84″): Found in wider garages, often in custom homes.
- 18 x 8 feet (216″ x 96″): The largest standard residential double door.

RV garages are increasingly common in Tucson — especially in communities like Vail, Corona de Tucson, and the northwest side near Marana where lot sizes accommodate RV storage. Standard RV garage door sizes include:
- 12 x 12 feet: Fits Class B campervans and smaller travel trailers.
- 14 x 14 feet: The most common RV garage door. Accommodates most Class C motorhomes and fifth-wheel trailers.
- 16 x 14 feet: For larger Class A motorhomes and toy haulers.
- 16 x 16 feet or larger: Custom sizes for commercial RV storage and oversized rigs.
RV doors require heavy-duty springs, reinforced tracks, and a 3/4 HP or 1 HP opener minimum due to their weight — often 300–500+ lbs.
How to Measure Your Garage Door
Measure the width of the opening at its widest point (not the door itself). Then measure the height from the floor to the top of the opening. Round to the nearest inch. Also measure the headroom (distance from the top of the opening to the ceiling or nearest obstruction) — you need at least 12 inches of headroom for a standard-lift door, and 3.5 inches for a low-headroom track system. Side room should be at least 3.75 inches on each side for the vertical tracks.
Non-Standard Sizes
If your garage opening does not match a standard size, custom doors are available from all major manufacturers. Custom sizing typically adds 15–30% to the door cost and may require 3–6 weeks for manufacturing. In Tucson, non-standard sizes are common in older Barrio and midtown homes, custom builds, and converted carports.
