Attaching a hinge to an interior door is easy with this Letsfixit guide and the process can be applied to anything requiring a hinge. Whether the door you are installing is on a cabinet, in a doorway, or on a box, you will need to know how to attach a hinge. Several different styles of hinges are available, such as off-set and piano, but all hinges are attached in the same basic manner. The steps here use an interior door as an example and to do this job, you’ll need some help.
Close your hinge. The hinge is made of three parts, two hinge leaves (which attach to your item) and the pivot point. With your hinge closed, the hinge leaves should be lying flush together. If they are not, then you have the hinge closed in reverse and need to correct this.
Use a tape measure to measure 8 inches down from the top of the door. Mark this spot with a pencil. Make another mark 8 inches up from the bottom of the door and a third in the centre of the door.
Place your closed hinge on the edge of the door (opposite the side with the handle) with the top of the hinge lined up with the first mark. The pivot point of the hinge should stick out past the face of the door on the side the door will swing toward when open. Screw the hinge into place on the edge of the door with some wood screws and a Phillips head screwdriver. Repeat this step to attach the other two hinges. Note that when attaching the centre hinge, centre the hinge on the mark; do not line up the top of the hinge with the mark.
Open the leaves of the hinges that are not attached to the edge of the door. Hold the door so the open leaves of the hinges lay flush against the inside of the door jamb. Have a helper screw the hinges into place on the door jamb.
