Internal doors
Internal doors in the UK come in two size families, a handful of constructions and three broad finish states. Ordering the right one means matching the family to your openings, choosing a core that suits how hard the door will be used, and deciding whether you are going to paint them yourself.
Everything below is an internal door: a leaf for a room inside a heated house, with no weather to keep out and no security job to do. That is what lets them be lighter, thinner and cheaper than anything on an external wall, and it is why an internal door in an exposed position fails quickly.
Filter by what you already know — the width you measured, the material you want, whether you are painting them — and use the guidance underneath if you are not sure yet.

Start with the opening, not the door
Almost every door order that goes wrong went wrong before anyone looked at a style. The opening decides which size family you are in, and the size family decides what you are allowed to buy.
Measure the height of the opening first. If it is close to 1981mm you are in the imperial family and the widths available to you are 610, 686, 762 and 838mm. If it is closer to 2040mm you are in the metric family and the widths are 526 through 926mm. The two do not mix, and the difference is far too large to trim away.
Then measure the width in three places, top, middle and bottom, because an opening in a house that has settled is rarely the same width all the way down. Work from the smallest number you get.
Where the money actually goes
The price difference between the cheapest and the dearest door on this page is mostly three things, and only one of them is visible from across a room.
- Material. A primed MDF face costs a fraction of a real oak veneer, and solid oak costs more again.
- Core. A hollow core is light and cheap; a solid core is heavier, quieter and takes ironmongery anywhere along the edge.
- Finish. A door that arrives ready to hang has had several coats applied under factory conditions, and you are paying for the labour you are not doing.
The things people forget to order
A door on its own does not make a working doorway. The parts that get left off an order are consistently the same ones, and they are the reason a delivery arrives and the job still cannot start.
Linings or frames, if the opening is new or the existing frame is being replaced. Hinges, in the right number for the leaf weight, which means three rather than two on anything solid or wide. A latch, and a handle set to work it. Architrave, if the wall finish is changing. And intumescent protection wherever the door is fire rated.
Ordering them together also matters for delivery. Doors are heavy freight, and a second delivery for a bag of hinges is an expensive way to remember them.
