Plane the door using an electric plane or sand for a smooth finish. If the existing frames aren’t square, buy a doorset with the door already hung in its frame to reduce problems and time.

2. Check if the new hinges fit the old ones in the frame. If not, mark the location and remove extra wood. Screw each hinge in place with one center screw, sticking the hinge knuckle out from the frame edge. Prop the door in the frame using wedges to ensure the correct gap at the bottom. Note that moulded, real wood veneer, foil, hardboard, and MDF hollowcore doors should have 2 hinges, while feature and primed doors should have 3 hinges.

How much clearance is needed between door and frame?

For standard doors, a gap of 1/8th of an inch is recommended to keep elements out, protect trim paint, and ensure smooth door closing and opening.

Measurements should be made from hinge side edge to latch side edge. Smaller doors like pocket doors or cabinet doors should have a smaller gap to avoid drag during opening and closing.

The most common type of door is the interior door, which can be made from various materials or a simple slab door. The gap should be tight enough to prevent visible light from coming through but not so tight that the door doesn’t open and close properly.

For a 36 x 80 door, the rough opening should be 38-1/2″ wide x 82″ tall.
