What is a standard door size? Unless you start choosing doors yourself, door sizes are something we might take for granted. Believe it or not, there is more than standard size throughout the United Kingdom. Many of Scotland’s doors are slightly different in dimension to English, Northern Irish, and Welsh counterparts.

The standard issue dimension is 1981 x 762 x 35mm. Which in old money is six feet tall and two feet and six inches wide. It is often referred as the 2’6” door variety of door. On built-in cupboards and wardrobes, typical door sizes are 1981 x 457/533 x 35mm.

For most internal doors, the average depth is 35mm. For fire doors, the depth is 45mm. The extra ten millimetres allow for the fireproofing material. Whereas many buildings in England and Wales have the standard 1981 x 762 x 35mm internal door, metric door sizes have gained greater popularity in Scotland. The average metric standard door dimension is 2040 x 726 x 40mm. The width can vary from 526mm to 929mm.

The last metric width is more generous than the minimum opening width required for disabled access. That is 838mm.
