UK Parking Standards state:

The term ‘one space’ used in the standards refers to standing area only and the recommended minimum dimensions for a car space are 4.8 metres by 2.4 metres. The term ‘commercial vehicle space’ used in the standards refers to the standing area required for the general type of commercial vehicle which would normally serve the particular development.

The following are standard space requirements of some typical vehicles. These may be used as basic minimum reference values but different layouts such as parallel, herringbone and in-line, have slightly different overall space requirements and detailed layout of parking spaces will be site specific.

Car 2.4 metres x 4.8 metres

Light Vans 2.4 metres x 5.5 metres

Rigid Vehicles 3.5 metres x 14.0 metres

Articulated Vehicles 3.5 metres x 18.5 metres

Coaches (60 seats) 3.5 metres x 14.0 metres

These dimensions refer to standing space only and do not take account of access, manoeuvring space or space required for loading/unloading.
