To make a door hang straight, start by tightening the hinges with a screwdriver. If the hinges are fine, you may need to adjust them by shimming the lower hinge, which can lift the door, or the upper hinge, which can tilt it back. Use thin pieces of cardboard or folded paper as shims. Check if the door is square by measuring diagonally from corner to corner; equal measurements indicate a square fit. Finally, make sure the door frame is level and plumb to ensure proper alignment.
