How many hinges
Three hinges is the usual answer for an internal door: two carries the weight badly and lets the door twist over time, particularly on solid timber. Heavier doors have their own requirements — follow the manufacturer's fitting instructions where they are supplied.
Hinge size follows door weight
A standard butt hinge suits most internal doors. Once you are into solid oak or a 44mm external door, the leaf weight climbs steeply — a 44mm door is roughly 40% heavier per square metre than a 35mm one — and the hinge has to be sized for it. Our product pages carry an estimated leaf weight for exactly this reason.
