Simple adjustments are easy to make, and many cabinets have hinges that allow you to make micro-adjustments in any direction.

For plain hinges, loosen the mounting screws just enough so that the hinges can move, but not so much that the door droops. Prop the door so that it is square with the cabinet opening, using shims if necessary, and then retighten the screws.

Most European-style hinges have built-in adjustment setups, and there are several types. One has a single screw connecting the two halves of the hinge. Loosen this screw slightly and you can reposition the door vertically or horizontally.

Another type has a sliding bar with a set-screw for horizontal adjustments, and a separate screw for vertical. The newest hinges have snap-on mounting plates that let you adjust height and depth.
