Small difference
Record the smallest measurement and note any visible irregularities.
Accurate opening measurements make the rest of the order easier. Use this self-help checklist and keep your notes beside you while configuring.

Measure the finished wall opening after plastering, flooring and skirting are complete where possible. Use millimetres and write everything down.
A difference of a few millimetres is common in renovation. If the measurements differ by more than 5 mm, measure again and check whether the opening needs preparation before you order. You can contact us if you want advice.
Record the smallest measurement and note any visible irregularities.
Measure again, check the finished surfaces and contact us only if you remain unsure.
Finish the floor and wall surfaces first, or tell us exactly what will still change.
A door that fits the wall still needs to reach the room. Check the front door, hallway, stairs and turning space before ordering. Leave at least 70 mm of clear working room beside the opening for fitting the frame.
Choose the door family, enter the opening size and continue directly to online checkout. Need reassurance first? Contact us whenever you want.
