Fix Crooked Cabinet Doors

Cabinet doors that hang crooked, sit too high or too low, or swing open on their own wreck the look of an otherwise finished kitchen. The good news is that almost every misalignment stems from loose or under-adjusted hinges, and the fix takes maybe 20 minutes and a screwdriver. Modern cabinet hinges—the cup-style hinges found on almost all face-frame and frameless cabinets made in the last 30 years—are infinitely adjustable in three planes: up and down, side to side, and in and out from the frame. You don't need to remove the door or call a carpenter. What you need is a clear-eyed look at where the door actually sits versus where it should be, a willingness to make small adjustments, and patience to dial it in. This is the kind of repair that feels fussy at first but becomes second nature once you understand the hinge mechanism.

1. Size Up the Problem. Close the cabinet door fully and look at the gaps on all four sides. Stand at eye level with the door and trace the gap with your finger on the top, bottom, left, and right. The gap should be even—usually between 2 and 3 millimeters on a standard cabinet. Note whether the door is high on one side and low on the other, pushed in at the top or bottom, or standing proud of the frame. Take a step back and see if the door appears to swing open on its own; this usually means the door is tilted and gravity is working against the hinge catch.
2. Find Your Adjustment Screws. Open the cabinet door and look at the hinge on the inside edge. You'll see two or three screws: one small screw directly behind the hinge cup (this is the depth adjustment), and two longer screws that pass through the hinge arm into the cabinet frame or side panel (these adjust vertical and horizontal position). On some hinges, the horizontal and vertical adjusters are in different locations. Familiarize yourself with which screw controls which direction before you start turning anything.
3. Level the Door Top to Bottom. If the door sits too high or too low, you need the vertical adjustment screw. This is typically the screw that runs horizontally through the hinge arm (parallel to the floor). Loosen it by one quarter-turn with your screwdriver—don't remove it entirely. Gently push or pull the door up or down to the correct height so the gap at the top matches the gap at the bottom. Once the door is positioned, tighten the screw again. Open and close the door to confirm it seats smoothly.
4. Center the Door Left to Right. If the door is too far to the left or right—creating an uneven gap between the door and the adjacent cabinet—use the horizontal adjustment screw. This screw typically runs vertically through the hinge arm (perpendicular to the floor) or is a separate eccentric screw depending on hinge design. Loosen it by one quarter-turn. Slide the door left or right until the gap matches on both sides. Retighten and test the door's swing.
5. Align Door Flush With Frame. If the door stands proud of the cabinet face or sits too far back into the frame, you need the depth adjustment. This is the small screw directly behind the hinge cup, often angled or off-axis. Loosen it by one quarter-turn and gently push or pull the door to align it flush with the cabinet frame and adjacent doors. The door should sit in the same plane as the face frame. Retighten and test.
6. Stop Doors From Drifting Open. If a door drifts open when you release it, the door is tilted slightly—usually forward or back on one hinge. This is often caused by undersized or worn hinges, loose frame screws, or a frame that's slightly out of square. Start by checking that the cabinet frame screws (the ones that hold the hinge to the frame) are tight; use your screwdriver to snug all of them. Then check the depth adjustment on both hinges and make sure they're in the exact same plane. If the door still swings, the hinges may be undersized; consider replacing them with heavier-duty cup hinges rated for the door's weight.
7. Align Paired Doors Perfectly. If two adjacent cabinet doors have different heights, start with the hinges on the shared stile (the center divider). Adjust the bottom hinge of the left door and the top hinge of the right door—these are the hinges closest to the center line. Make micro-adjustments to bring both tops to the same height and both bottoms to the same height. Work from the outside in so that the center gap remains consistent.
8. Verify Cabinet Frame Is Square. If doors still won't align after hinge adjustment, the cabinet frame itself may be racked (twisted). Place a level across the top of the cabinet and check for true. Measure diagonally from corner to corner inside the cabinet—both diagonals should be the same length. If the frame is out of square by more than a quarter-inch, the cabinet may need to be shimmed during reinstallation or the frame structure needs bracing. Minor twists can sometimes be compensated by setting one hinge deeper than the other.
9. Lock Down Every Screw. Before you call the job done, go through every screw on every hinge and make sure it's snug. Use steady pressure on the screwdriver—you're not trying to snap the screw. A loose mounting screw will cause creep over time, and a door will gradually fall out of alignment again within weeks. Check the frame mounting screws too (the ones that hold the hinge to the cabinet structure); these loosen from constant door closing and opening.
10. Confirm Smooth Door Swing. Open and close the door 5-10 times at different angles—close it gently, close it normally, close it firmly. Watch for any drift, binding, or uneven gaps. Open it to 45 degrees, 90 degrees, and fully back. The door should swing smoothly without hitting the frame or adjacent doors. If you hear a click or feel resistance, there's still an alignment issue or the door is hitting something; go back and check hinge adjustment and frame squareness.
11. Perfect Handle Alignment. Now that the doors hang straight, check if the handles or knobs line up visually. If two side-by-side doors have different handle heights because one door sat too high before adjustment, you may need to relocate the handle on one door to restore the symmetry. Drill out the old holes and drill new ones at the matching height. Fill the old holes with wood filler if they're going to show.
