Standard garage and parking space sizes

These are the typical US sizes our fit checks use. Real garages vary a lot, especially older ones, so measure yours: inside depth from the back wall to the closed door, inside width between walls (or shelves), and the door opening itself.

Garages

GarageInside (width × depth)Door opening (width × height)

2-car20′ × 20′16′ × 7′
Large 2-car24′ × 24′16′ × 8′
3-car32′ × 22′16′ × 7′

Single doors are usually 8–9 ft wide, double doors 16 ft; 7 ft is the standard height, 8 ft is common on newer and custom homes.

Parking spaces

There is no national standard: local zoning codes set the minimums. Standard stalls are usually 8.5–9 ft wide and 18–20 ft long; compact stalls 7.5–8 × 15–16 ft; parallel spaces 8 × 20–24 ft.
