The Hinge Mistake That Makes Every Cabinet Door Look Crooked

Here's the assumption that gets almost every cabinet job in trouble. If the gaps between the doors aren't even, people assume the cabinets must be out of square, or the doors were cut wrong. Nine times out of ten, that's not it at all. The carcasses are fine, and the doors are the right size too.

Nobody adjusted the hinges. European cup hinges are built to be adjusted after the door's hung, every single time, not just screwed on and left the way they came out of the box on install day.

They've got screws for depth, height, and side-to-side movement, usually hidden right there on the hinge arm and the mounting plate where nobody thinks to look. Skip that step and even a perfectly square cabinet, built by someone who knows exactly what they're doing, ends up looking like a dog's breakfast once the doors go on.

• One door sits proud of its neighbour by a couple of millimetres, so it catches the light differently
• The gap at the top of a door is noticeably wider than the gap at the bottom of the same door
• Two doors meeting in the middle of a run don't line up, even though both were cut to the exact same size
• A door rubs against the cabinet next to it every single time it opens or closes
• The reveal looks fine from across the kitchen but clearly wrong the second you stand right in front of it
• You've already re-cut a door thinking it was the wrong size, and it still doesn't sit right after the re-cut
• A whole run looks good until you hit one cabinet where the gap suddenly jumps

If any of that sounds familiar, put the saw down before you cut anything else. Cutting a brand new door will not fix a hinge that's never actually been touched since it came out of the bag. Every cup hinge has three separate adjustments built into it, and most fitters only ever find one of them, usually by accident, usually under time pressure to get the kitchen looking done before the client walks back in.

There's a side screw that moves the door left or right, which closes the gap between two doors sitting next to each other. There's a height screw that moves the door up or down relative to the one beside it. And there's a depth screw, sometimes called the cam, that moves the whole door in and out from the cabinet face — that's the one that actually changes how wide the reveal looks to the eye.

Most people find the side screw first, nudge the door roughly straight, and stop there because it looks close enough in the moment. That's exactly why the top of two doors lines up fine but the bottom doesn't match at all.

Nobody touched height. It's also why a door that's already been 're-squared' twice still looks slightly off once the kitchen's finished. Nobody touched depth, and the reveal never actually changed, no matter how many times the door itself got adjusted left and right.

Turn these screws in small amounts, a quarter turn at a time, then close the door and actually look at it before you touch anything else. Full turns on most hinges will swing a door several millimetres in one go, and it's very easy to overcorrect and spend an entire afternoon chasing the same gap back and forth without ever landing on it.

That line matters because adjustment has real limits. If the carcass itself is out of square, or the hinge holes were bored off-centre to begin with, you'll run out of adjustment travel before you run out of problem to fix. No amount of turning a screw puts a crooked box back to square. Sort the install first. Adjust the hinge second, not instead of it.

What you're actually aiming for changes depending on the door type you're hanging. Inset doors usually want a small, dead-even gap running right round the whole door, tight and consistent, nothing more than a sliver anywhere. Overlay doors are more forgiving on how wide that reveal looks, but far less forgiving on clearance, since neighbouring doors need real room to swing past each other without catching.

Standard cup hinges also have a limit on how much overlay they can physically handle before they stop working properly. Push a door past that limit and it won't close right no matter how much you adjust it afterwards. That's a sign you need a different hinge for the job, not a sign you need to keep fiddling with the one you've already fitted.

Worth doing on any run you're not fully confident about: hang one test door first, adjust it until it genuinely looks right, then use that door as your reference for every other one on the same run. Stand back from it, not just up close, since a gap can look fine six inches away and still read wrong from across the room. Guessing fresh on each door wastes far more time than setting one good reference early.

Here's the order that actually works, door by door, instead of jumping between screws hoping one of them fixes everything at once:

• Hang the door and let it sit closed for a minute before judging anything — hinges settle slightly once they're actually under load
• Fix height first on both the top and the bottom hinge, so the whole door sits level with the one beside it
• Fix side next, so the gap between two doors is even from the top all the way to the bottom, not just at eye level
• Fix depth last, to even out the reveal against the cabinet face once height and side are already sorted
• Check the door swings clear of the cabinet next to it before you call that door finished
• Move on to the next door and compare it against the one you just finished, not against a number written on a drawing
• Walk the whole run again once every door's hung, because a gap that looked fine on its own sometimes doesn't once it's next to its neighbour

That second-to-last point is the one that trips people up the most. You're not matching every single door to a spec sheet or a measurement written down weeks ago. You're matching every door to the one right beside it, because that's the comparison a client's eye will actually make.

A reveal that's slightly off from the original drawing but dead consistent across the whole run will always look better than one that's technically correct everywhere and inconsistent in just one spot. Consistency beats precision here, every time.

Corner cabinets are the one place this gets genuinely harder, not just more fiddly to deal with. Where two doors meet at a corner, you've effectively got two edges and two separate gaps instead of one, so any small mismatch between them doubles up right where it's most visible.

If the stile widths either side of that corner aren't close to matched, no amount of hinge adjustment will close that gap evenly. You can turn screws all day and it still won't sit right, because the problem was never in the hinge to begin with.

That one's worth catching at the cutting list stage, long before it ever becomes a hinge problem on site with the client due round the corner. If you know a run has a corner return in it, size the doors so the stiles either side come out close to matched before anything's actually cut. It saves you an hour fighting hinges later, trying to adjust your way out of a sizing problem a screwdriver was never going to solve, no matter how patient you are with it.

Skip the adjustment step altogether on a job and it rarely costs you money up front. It costs you time and trust instead, and both of those are harder to get back than a few minutes with a screwdriver. A client's eye goes straight to the one uneven gap in an otherwise good kitchen, every single time they walk past it, no matter how square the carcasses are or how clean the rest of the fit-out is.

Then there's the second visit. A snag that's a genuine ten-minute hinge tweak turns into a whole extra trip back to site, because nobody checked it properly before handover and it only got noticed once the kitchen was already signed off. Multiply that across a handful of jobs a year and it adds up to a lot of driving for something that takes less time than making a coffee on site. Other trades start double-checking doors on the next job too, once they've seen one go out the door looking rough.

None of this is really a skill problem, and it's not about buying better hinges either. It's a five-minutes-a-door habit that gets skipped when a job's running late and the install feels like the last thing standing between you and the next job on the list.

Build the hinge check into the end of the hang, the same way you'd check a drawer runs smooth before moving on to the next one. Do that consistently and it stops being extra work. It just becomes part of hanging the door, same as driving the screws in.
