Can you cut an interior door? Of course! Sometimes, it might be necessary to adjust the size of an internal door.

The sides of the door usually shouldn't need a whole lot of wood removing, and it's a reasonably simple job – as long as you've got a steady hand! Use a hand plane (or a power plane) to shave off equal amounts from each side, using the pencil lines you marked earlier.

There should be a 2mm or 3mm gap between the door and the frame on both sides and the top. If you do need to cut the door down to size, keep in mind that you need to cut all four sides of the door equally whenever possible to retain an accurate shape or pattern if the door is panelled.
