What are the standard door sizes in the UK?

5 min read Doors Tips

There are various standard door sizes in the UK and knowing them is useful for anyone looking for new or replacement doors. It’s worth bearing in mind that made-to-measure doors, which are manufactured to a specific size, are available too.

In order to clue you up on standard UK door sizes, we’ve created this handy guide.

Standard uPVC door size

The standard size for uPVC doors depends on the style of door. For example, uPVC sliding doors are wider than uPVC front doors by default because of their designs. This is also true for aluminium and timber doors, which also come in a range of styles. So, for the purposes of this guide, the focus will be on the style of the door rather than the material they are built from.

Standard front door height

As the primary door is usually the front door, the most common height for front doors is 80 inches. However, there are several popular standard heights for them:

  • 78 inches (6.5ft)
  • 80 inches (6.6667ft)
  • 82 inches (6.8ft)
  • 84 inches (7ft)

It’s also important to bear in mind that these are the standard heights for back entrance doors and stable doors too.

Our Range of Doors

Standard front door width

According to the Internal Residential Code, the primary door to the house must be at least 36 inches (3ft) wide. The primary door is usually the front door, which means the most common width for them is 36 inches. However, front doors are available in several standard sizes:

  • 28 inches (2.3ft)
  • 30 inches (2.5ft)
  • 32 inches (2.6667ft)
  • 36 inches (3ft)

The standard widths mentioned above are for back doors too.

Standard size for double front doors

If the entranceway to your home is quite large, double front doors can create the grandiose feel that your home deserves. Like single front doors, they need to be at least 80 inches (6.6ft) tall, but there are several common widths for them:

  • 60 inches (5ft)
  • 64 inches (5.3ft)
  • 72 inches (6ft)

If would like double front doors fitted with sidelights, this will increase their overall width again.
