It is usual for the door to require some height and width adjustment for a perfect fit. This is achieved by temporarily holding the door in place and measuring for fit. Get someone to help you lift the door, or else use a board lifter. Once you are satisfied with the fit of the door, the next task is to attach the hinges.
With a level floor, 1 inch is needed, but any undulations may require more. Plane off the required amount and check for clearance. Always plane from the outer edge inward, to prevent wood from splitting
Place the door on the floor, hinge-side up. Make a pencil mark 6 inches down from the top of the door. Place the hinge below the mark, and trace around it. Repeat for the lower hinge, but this time position it above the mark.
