Will they fit? UK parking bay and garage

CarParking bay 4.8 × 2.4 mSingle garage, 7 ft door
Ford Fiesta (2017)Fits comfortablyFits comfortablycheck my garage
Audi A1 (2018)Fits comfortablyFits comfortablycheck my garage

Assumes a UK standard parking bay of 4.8 × 2.4 m and a typical UK single garage of 4.8 × 2.4 m inside (2.1 m high) with a 7 ft × 6 ft 6 in (213 × 198 cm) up-and-over door. Where we have no width-with-mirrors figure we add 20 cm to the body width. Garage: “comfortable” means at least 40 cm spare in length and 35 cm in width with mirrors, driving in with mirrors out; “tight” means at least 20 cm spare in length and 40 cm in body width, mirrors folded. Bay: “comfortable” leaves 30 cm in length and 20 cm each side. Garages and bays vary a lot — measure yours and use the garage fit checker, or see UK garage and parking space sizes.
