Internal Door Buying Guide

What size internal door do I need?
Standard UK internal doors are 1981mm x 762mm (6'6" x 2'6") or 1981mm x 686mm (6'6" x 2'3"). Always measure your existing frame before ordering. Most of our doors have a trimming allowance of up to 10mm per side.

Pre-finished or unfinished?
Pre-finished doors arrive ready to hang with no painting or varnishing required — ideal for busy households. Unfinished doors give you full control over the final colour and finish.

Solid or hollow core?
Solid core doors offer better sound insulation and a premium feel. Hollow core doors are lighter and more affordable — great for bedrooms and cupboards.
