You open a kitchen cabinet, glance at the row of doors, and one of them is just… off. Sitting a little crooked, a gap wider on one side, maybe rubbing against its neighbour. It’s a small thing, but once you’ve seen it, you can’t unsee it.
Here’s the good news: nine times out of ten, you don’t need new doors or a carpenter. You need to adjust the hinges and modern cabinet hinges are built to be adjusted in minutes, once you know which screw does what.
The short answer: cabinet doors go out of alignment because hinge screws loosen over time, the cabinet or door shifts slightly, or the hinges were never set correctly to begin with. Adjusting the three screws on a standard concealed hinge for side, depth, and height brings the door back into line.
Let’s get into why it happens and exactly how to fix it.
Why Cabinet Doors Drift Out of Alignment
Doors don’t usually go crooked overnight. It’s gradual, and there’s almost always a simple reason behind it.
Daily use is the big one. Every open and close puts a tiny load on the hinges, and over months and years, screws work loose and the door settles lower or sideways. Weight plays a part too a heavy door, or one carrying a mirror or thick panel, pulls harder on its hinges and drifts faster.
Then there’s humidity. In kitchens and bathrooms, moisture makes wood swell and contract, nudging doors out of position with the seasons. And sometimes the door was simply never aligned properly at installation, so it was fighting a losing battle from day one.
Whatever the cause, the cure is the same: the hinges.
Understanding the Three Adjustments
Almost every modern cabinet uses a concealed (European) hinge, and the beauty of these is that they adjust in three directions. Once you know what each screw controls, the whole thing stops feeling like guesswork.
- Side-to-side (left/right): The main screw, usually closest to the door. Turning it moves the door sideways to even out the gap between doors.
- Depth (in/out): Controls how close the door sits to the cabinet frame useful when a door sticks out or presses in too far.
- Height (up/down): Set on the mounting plate where the hinge attaches to the cabinet. Loosen it slightly to raise or lower the whole door.
Most alignment problems are fixed with the first one. The other two are for fine-tuning.
How to Adjust Cabinet Hinges – Step by Step
You’ll need just a screwdriver, usually a Phillips head. Work on one door at a time and make small turns – a quarter-turn changes more than you’d expect.
- 1.Look closely and find the problem. Is the gap uneven side to side? Is the door too high or low against its neighbour? Does it stick out or sit too deep? Naming the problem tells you which screw to touch.
- 2. Fix the sideways gap first. Turn the side-adjustment screw on each hinge a little at a time, checking the gap as you go. Clockwise and anticlockwise move the door in opposite directions – small turns, frequent checks.
- 3. Set the height if needed. If the door sits too high or low, slightly loosen the screws on the mounting plate, nudge the door up or down until it lines up, then tighten again.
- 4. Adjust the depth last. If the door doesn’t sit flush poking out or pressing in – use the depth screw to bring it level with the cabinet face.
- 5. Tighten everything and test. Once it looks right, firm up all the screws and open and close the door a few times. It should swing smoothly and close flush, with even gaps all around.
That’s it. Most doors come back into line in under five minutes.
When Adjustment Isn’t Enough
Sometimes the screws won’t hold, or no amount of turning fixes the alignment. That’s usually a sign of something beyond adjustment.
Stripped screw holes, worn-out hinges, or corroded hardware won’t respond to fine-tuning – they need replacing. If a door keeps drifting back out of line within days of every adjustment, the hinges themselves are likely worn or were the wrong grade for the door’s weight. In humid kitchens especially, low-quality hinges corrode and lose their grip, and no adjustment will save them.
At that point, upgrading to quality, corrosion-resistant hinges rated for the door’s weight is the real fix – and it’s the last time you’ll have to think about that door for years.
Quick Reference
| Problem | Adjustment | Screw location |
| Uneven side gap | Side-to-side | Front screw on hinge |
| Door too high / low | Height | Mounting plate screws |
| Door sticks out or in | Depth | Rear screw on hinge |
| Won’t hold after adjusting | Replace hinge | – |
Small Fix, Big Difference
A misaligned cabinet door is one of the most satisfying quick fixes in a home — a few turns of a screwdriver and a whole row of cabinets suddenly looks intentional again. Start with the side screw, work in small turns, and only reach for replacements when adjustment genuinely won’t hold.
And if you’re specifying cabinets from scratch, remember that the hinge is doing all the quiet work here. Good that stays put and resists corrosion means far fewer crooked doors down the line.
