A sound leaf that only rubs or latches poorly may suit adjustment or hardware repair instead. Replacement is considered for an unsuitable or damaged leaf after checking that the existing opening can accept the proposed door.
Factory cut-outs can restrict which handle or latch will fit. Show the hardware from both sides and the latch edge. Ordinary compatible hardware transfer can be considered, but existing holes should not be assumed to match a different product simply because both are internal doors.
A nominal door size is only a starting point. Measure the existing leaf and show the clear opening at several points. Differences can affect the available margins, so ordering a replacement before checking the frame may leave too little material for a suitable fit.
Check the swing across the actual floor, including rugs and any planned flooring change. The aim is a workable clearance with an aligned leaf. Removing excessive material to compensate for an unsuitable opening is not a substitute for checking compatibility first.
Hang the compatible replacement leaf, fit agreed ordinary hardware and check floor clearance, alignment and closing in the unchanged opening. Scope limits: Ordinary compatible internal leaf replacement only. No structural opening changes, fire or smoke-rated doors, certification, locksmith services or powered security integration.
