How to Adjust Kitchen Cabinet Hinges: Step-by-Step

August 25, 2026

Cabinet doors often drift out of alignment over time due to daily use, the natural settling of kitchen carcasses, or temperature fluctuations. If you find yourself wondering how do I adjust kitchen cabinet hinges to eliminate unsightly gaps or stop doors rubbing against one another, the solution is remarkably straightforward. Standard European concealed hinges—commonly featuring a 35 mm cup—offer three-way adjustment that allows you to correct vertical, horizontal, and depth alignment using nothing more than a standard screwdriver.

Understanding 3-Way Hinge Adjustments

Modern concealed cabinet hinges, including modern soft-close hinges, are engineered with built-in adjustment screws. Before turning any screws, inspect the door to determine which plane needs correction:

Side-to-Side (Horizontal): Fixes doors that overlap in the middle, sit crooked, or leave an uneven gap between adjacent units.
Height (Vertical): Raises or lowers the entire door to align the top and bottom edges with surrounding cabinetry.
In-and-Out (Depth): Adjusts the gap between the back face of the door and the front edge of the cabinet carcass to ensure the door closes flush.

Step-by-Step Guide to Aligning Cabinet Doors

Always work systematically, adjusting one hinge at a time while checking the door position after every minor turn.

1. Correcting Side-to-Side Alignment (Horizontal)

The horizontal adjustment screw is located towards the front of the hinge arm (closest to the door). Turning this screw clockwise moves the edge of the door closer towards the side panel (carcass edge), while turning it anti-clockwise shifts the door inwards towards the centre of the unit. Adjust the top or bottom hinge independently to straighten a sloping door.

2. Adjusting Door Height (Vertical)

Vertical adjustments are typically made on the mounting plate attached to the inside wall of the carcass:

Slightly loosen the two fixing screws that secure the mounting plate to the carcass (one top, one bottom).
Manually slide the door up or down to align with neighbouring units.
Retighten the screws securely while supporting the door weight.

Some advanced replacement mounting plates feature an integrated cam screw that allows vertical movement simply by turning a central screw, eliminating the need to loosen the plate fixings.

3. Setting the In-and-Out Gap (Depth)

The depth screw sits towards the rear of the hinge arm. Loosening this screw allows the hinge arm to slide forwards or backwards along the mounting plate. If the door catches on the cabinet frame when opening, pull the door slightly forwards to increase clearance before tightening the screw back down.

Troubleshooting Common Hinge Problems

If adjusting the screws does not resolve the alignment issue, check for these common mechanical faults:

Loose Screws in Worn Timber: If fixing screws spin without gripping the chipboard carcass, remove the screw, pack the hole with wood filler or wooden dowels, and refit.
Bent Hinge Arms: If a door has been forced open past its standard angle, the internal hinge mechanism may be bent. In such cases, swapping the damaged hardware for new soft-close hinges is the most reliable remedy.
Cracked Mounting Plates: Check the baseplate for hairline fractures or stripped threads. Installing replacement mounting plates restores stability without needing to replace the door or hinge cup.
