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.
DOOR SIZES: BUILDING REGULATIONS
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.
