Door Sizes

Your guide to UK Door Sizes

We explain below the advertisement the standard door sizes in the UK. These are governed both by Building Regulations and by industry practice.


Part M of the UK building regulations covers 'Access and Facilities for Disabled Use'. It requires that in all new homes and other residential buildings there should be a minimum clear width and a maximum threshold height for the principal entrance of the dwelling; this is usually considered to be the front door. This is to provide easy access for those in wheelchairs.

The required clear opening width is at least 775mm. This is measured between the door stile and the face of the door when it is opened at 90 degrees, as shown in the diagram above. This minimum requirement corresponds to a door 33 inches (919mm) wide, which would typically be 6ft 6 inches high.


Entry Door Sizes

The usual range of sizes for entry doors is: 6'6" x 2'6" (1981mm x 762mm), 6'8" x 2'8" (2032mm x 813mm), and 6'6" x 2'9" (1981mm x 838mm). Metric sizes are also available, namely 2000mm x 807mm and 2040mm x 826mm.

Paired entry doors are commonly available in a size, for the complete pair, of 6'6" x 3'10" (2000mm x 1106mm).

Internal Door Sizes

The usual range of sizes for internal doors is: 6'6" x 2'3" (1981mm x 686mm), 6'6" x 2'6" (1981mm x 762mm), and 6'6" x 2'9" (1981mm x 838mm).

Kitchen Cupboard Door Sizes

The standard widths for kitchen cupboard doors are 300mm, 400mm, 500mm, 600mm, 800mm, and 1000mm. Wall unit doors are usually 600mm or 720mm high. Base units are usually 880mm high.
