Cabinet Hinge Adjustment: Side, Depth, and Height Fix

The short answer

Modern European-style cabinet hinges (Blum, Salice, Grass, Hettich, Hafele) all share the same three-axis adjustment layout: one screw moves the door left and right, one screw moves the door in and out, one screw moves the door up and down. The names of those screws and which one is which vary by brand, but the diagnosis is always the same and the order is always the same.

Fix in this order: side-to-side first, then depth, then height. Doing height first creates new side-to-side problems; doing depth before side-to-side leaves the door sitting on the cabinet frame and pulls every other adjustment off. Walk through the three axes once for each problem door and the system aligns reliably.

None of this requires removing the door, unscrewing the hinge from the frame, or shimming the mounting plate. If you reach for a chisel to mortise the hinge deeper into the door, you have skipped the adjustment step.

What each screw actually does

On a standard cup hinge (the visible round cup sits inside the door, the arm reaches to a mounting plate inside the cabinet), three screws are exposed when the door is open.

The front screw, closest to the door face, controls side-to-side movement. Turning it clockwise or counterclockwise rotates the door left or right relative to its opening. Most brands move the door away from the hinge side when turned one direction and toward it when turned the other; one careful test turn tells you which way your specific brand goes.

The back screw, deeper in the cabinet on the hinge arm itself, controls depth — how far the door sits from the cabinet face. Clockwise typically pushes the door out (away from the cabinet), counterclockwise pulls it in. This is the screw to use when the door catches on the adjacent door or the cabinet frame as it closes.

The vertical screw, usually on the mounting plate inside the cabinet rather than on the hinge arm itself, controls height — how far up or down the door sits in its opening. Some plates have a separate slot you loosen first, slide the plate up or down, and retighten; others have a captive screw that moves the plate as you turn it.

Not all hinges expose all three controls equally easily. Cheaper inset hinges often combine height and depth onto two screws on the same arm; older European hinges may have only side-to-side adjustment. The principle still applies even if the implementation is uglier on cheaper hardware.

The diagnostic step: which screw to turn

Before touching a screw, stand in front of the cabinets and look at the gaps. The fix is almost always written on the cabinet face.

If two adjacent doors have an uneven gap between them — the gap is wider at the top than the bottom, or wider on the left than the right — that is a height or side-to-side problem on one or both doors. Note which door is the offender (usually the one whose gap is uneven on both sides) and start with side-to-side on that door.

If the door catches on the cabinet face when closing, or sits proud of the face when closed, that is a depth problem.

If the door sits low compared to the adjacent door, or rubs the cabinet bottom when closing, that is a height problem.

If the door swings open by itself or slams shut from a certain angle, that is a hinge plate looseness problem and the screws holding the plate to the cabinet need tightening — not the adjustment screws.

Most real-world misalignment is a mix. Diagnose the worst issue first, fix that, then check whether the other issues remain or were caused by the first one being wrong.

Adjusting side-to-side

With the door open, find the front screw on each of the door's hinges (most doors have two hinges; some have three). For brands that use a Pozidriv or Phillips head, use the matching driver; for newer Blum hinges that use a small hex, use the matching key. Turning a small amount goes a long way — a quarter turn often moves the door 1-2 millimetres.

Turn the same direction the same amount on both hinges. If you adjust one hinge but not the other, the door becomes parallelogram-shaped to its opening — top sits left, bottom sits right — and you create a tilt that did not exist before.

Close the door and check the gap to the adjacent door or frame. Repeat in small increments until the gap is even top to bottom along the strike side of the door.

The common mistake is turning the wrong screw on both hinges in opposite directions trying to tilt the door. That is the height adjustment's job, not side-to-side. Keep the two side-to-side screws in lockstep.

Adjusting depth (in and out)

With the side-to-side gaps even, check the closed door's position relative to the cabinet face. Run a finger across the seam — the door face should be flush with or very slightly proud of the cabinet face, never recessed behind it (which traps grease and looks unfinished).

If the door sits too deep, turn the depth screw on both hinges clockwise the same small amount to push the door out. If it sits too proud, counterclockwise to pull it in. Quarter turns at a time.

The depth adjustment also fixes a common door behavior: closing softly at the top but catching at the bottom (or vice versa). Adjusting only one hinge's depth screw tilts the door's vertical line. Use this deliberately when the door does not sit parallel to the cabinet frame — tighten the top hinge's depth a touch more than the bottom, or vice versa, to swing the door into parallel.

Never back the depth screw out so far that it stops engaging the hinge arm. The screw needs to seat under tension; an unseated depth screw lets the door float on the cup spring alone and the door will not close reliably.

Adjusting height (up and down)

Height adjustment lives on the mounting plate. With two doors side by side that should align horizontally, look at the bottom edges. If one is a millimetre lower, raise it with the height screw on its hinges (or lower the other one).

The routine on Blum Clip-Top and similar modern plates: loosen the plate's clamp screw or turn the height screw counterclockwise to free movement, slide the plate up or down with a finger, hold position while tightening, recheck. Some plates have a captive screw that does both jobs — turn clockwise to raise, counterclockwise to lower, no separate clamping step needed.

Adjust both hinges on the same door by the same amount. If you raise the top hinge but leave the bottom, you cock the entire door upward at one corner.

Height is the adjustment most likely to throw off side-to-side, because raising or lowering changes how the cup sits in the door. After a height adjustment, recheck the side gap and tweak the front screw if needed.

Soft-close: when the door slams or stalls

Soft-close hinges have a small dampener built into the hinge arm — usually a visible cylinder. It slows the last 20-30 degrees of closing so the door does not slam shut.

If the door slams anyway, the cause is usually one of three: the dampener has been switched off (some brands have a small toggle on the arm — set to minimum or maximum closing speed); the dampener is failing (no fix except hinge replacement); or the door is light enough that the closing spring fully overrides the dampener (some brands sell heavier-tension dampeners as drop-in upgrades for light doors).

If the door stalls before closing and you have to push the last inch, the dampener is set too strong for the door's weight, or the soft-close is interfering with the closing spring. Lower the dampener strength toggle if your brand has one. If not, the door is heavier than the hinge was specified for, and the right fix is to switch to a heavier-rated hinge.

Soft-close behavior also degrades with age. After ten years or so, the dampener oil can dry and the action becomes inconsistent. Replacement hinges of the same model are usually available; swap takes about five minutes per hinge.

When adjustment will not fix it

Some cabinet door problems live outside the hinge's adjustment range.

A cabinet box that is racked out of square (the opening itself is parallelogram-shaped rather than rectangular) cannot be solved by adjusting the door. The fix is on the cabinet itself: shim the cabinet level, retighten the case screws, or accept that this particular cabinet will never close perfectly. Tall pantries are common offenders.

A door that has warped — usually a thin slab door that has dried out in a hot kitchen — cannot be straightened by hinge adjustment. The fix is to flatten the door with weight and humidity over weeks, or replace it.

Mounting plates pulled loose from the cabinet wall (small screws into particleboard backs are the usual victim) will not hold any adjustment because the plate itself is moving. Move the screws to fresh material, fill the failed holes with toothpicks and wood glue and let dry, then redrive into the toothpick plugs for a fresh grip.

If the door's cup is loose in the door itself, that is a different repair entirely — the cup screws into the door, and if the holes have stripped out, replacing those screws with longer ones or filling the holes is the fix.

Maintenance that keeps doors aligned

Check door alignment twice a year. Kitchens go through humidity cycles that move wood by small amounts, and cabinets that were perfect in March can be off in August. A quick visual pass at the start of each season catches small drift before it becomes a struggling door.

Wipe the hinges with a microfibre cloth annually. Cooking grease accumulates on the arm and the cup and slows the action over years. A drop of light oil on the pivot of an aging hinge often restores smoothness; do not use heavy oil, which traps dust.

Resist the urge to fix a single misaligned door by turning every screw you can see. Diagnose first, adjust one axis at a time, recheck after each turn. Most hinge problems take three or four small adjustments to solve cleanly; doors that resist easy adjustment are usually telling you the problem is somewhere else.

Tools that make hinge adjustment painless

A matched screwdriver set saves the most time. Most Blum hinges use Pozidriv #2 heads on the older models and small Allen keys on newer ones; Salice, Grass, and Hettich often use slotted, Phillips, or Pozidriv depending on the era. A short-shaft driver clears the cabinet interior better than a long one; the long driver fights the cabinet wall on every adjustment.

A small bubble level reads door-to-door alignment more reliably than the eye. A 6-inch torpedo level held against the door bottom or top edge tells you whether the door sits true or tilts; pencil-mark tilt direction and amount, then adjust by the indicated amount and recheck.

A mechanical pencil for marking adjustments helps. Drawing a small line on each adjustment screw before turning lets you see exactly how much you turned and roll back if the move went the wrong way. Without the pencil mark, the third or fourth adjustment in a session loses track of where it started.

Why kitchen doors drift over time

Kitchens cycle through humidity changes that pull and push wood. A cabinet built and installed in dry winter air absorbs moisture in the next humid summer, swelling slightly; a cabinet built in humid summer dries out in winter, shrinking slightly. Doors that aligned perfectly at install can drift a millimetre or two over the first year as the wood reaches equilibrium with the room.

The initial drift is the largest. After the first full year, drift slows substantially and seasonal cycles cause only small annual movement. Plan to do a full alignment pass once during the first year of new cabinets, then twice a year afterward for maintenance.

Wood doors drift more than thermofoil or laminated MDF doors because the wood is moving directly with humidity. If your cabinets have wood doors and you live in a climate with large humidity swings, expect more frequent adjustment. If your cabinets have foil-wrapped MDF, the doors themselves stay stable and most drift comes from the cabinet boxes (which may also be wood).

Knowing this in advance makes the maintenance feel like normal upkeep rather than a fault in the cabinets. Properly aligned cabinet doors are the result of a small routine, not a perfect install.
