average width of a car uk
With the average width of cars being 1.8 m and an allowance of 800 mm for the door access and a clearance of 300 mm on the passenger's side, then a minimum width of 2.9 m is needed.ounds obvious but that's the short answer, the size of popular UK cars can be found at car sizes. I would recommend that a minimum size of a garage should be 3 m wide and 5 m long internally. Now for the long answer, there are no minimum sizes for garages.
