Measured against a garage 2.6m wide and 5.0m deep, with a 2.13m door opening. (Standard single garage)
Measure the inside, not the outside, and measure the door opening at its narrowest.
The size most modern single garages are built to.
A car is treated as fitting lengthwise with at least 300 mm to spare, so the door can shut and you can get past the back. Getting out assumes a door needs about 600 mm of swing, on top of 150 mm of air beside the body. Folded mirrors are assumed to still stand about 80 mm proud of the bodywork. These are rules of thumb, not standards, so measure before you buy.
