Measure the case depth and backset of the existing latch. Handle type, door stile width and clearance from the frame also affect the choice.
Spring Latches for Internal Doors
Tubular latches hold internal doors closed and release when the lever handle or knob turns. Their compact case fits into a drilled pocket in the door edge, making them a common choice where a key-operated lock is not required.
Case depth and backset determine where the spindle sits on the door face. Measure the existing latch when replacing one, and allow enough clearance between a knob and the frame. Compatible door handles and knobs should use the same spindle arrangement.
Mark the centre line carefully, drill straight and recess the faceplate so it sits level with the door edge. The wider locks and latches collection covers doors that also need privacy or keyed security, while correctly sized door hinges help the latch meet its keep cleanly.

It can provide the latching action, but privacy also requires a compatible deadbolt, bathroom lock or other locking fitting.
Paint, poor alignment, overtightened fixings or a worn spring can restrict movement. Remove the latch and test it before altering the door.
Most use a standard square spindle, but the spindle size, spring strength and bolt-through fixing requirements should still be checked.
