How to Adjust Cabinet Door Hinges: A Step-by-Step Guide

Over time, kitchen cabinet doors frequently drop, rub against adjacent units, or sit unevenly. This movement is entirely normal and typically caused by daily use, the weight of the doors, or seasonal timber expansion. Fortunately, modern concealed hinges—often referred to as European or cup hinges—are engineered with built-in three-way adjustment mechanisms. If you are wondering how do i adjust cabinet door hinges without calling in a professional joiner, all you need is a standard cross-head screwdriver and a few minutes of patience.

Understanding 3-Way Concealed Hinges

Concealed hinges sit inside a 35 mm cup drilled into the back of the cabinet door and mount onto a steel plate fixed to the carcass. High-quality kitchen hinges feature three distinct adjustment screws that control the door across three axes:

• Vertical adjustment (Height): Moves the door up or down to align the top and bottom edges with neighbouring cabinets.
• Horizontal adjustment (Side-to-side): Shifts the door left or right to set equal gaps between adjacent doors.
• Depth adjustment (In-and-out): Moves the door closer to or further away from the cabinet carcass to ensure it closes flush.

Step 1: Vertical Adjustment (Moving Doors Up or Down)

If the top edge of a cabinet door does not line up with the adjacent unit, or if the bottom edge catches on the frame below, you must adjust the height. Unlike side adjustments, vertical positioning is usually controlled via the mounting plate attached to the cabinet carcass.

1. Locate the top and bottom mounting screws on the hinge plate inside the carcass.
2. Loosen both screws slightly on all hinges attached to that specific door (usually two or three turns is sufficient).
3. Manually slide the door up or down until it aligns level with the adjacent units.
4. Hold the door firmly in place and retighten the mounting plate screws securely.

Step 2: Horizontal Adjustment (Fixing Gaps and Overlaps)

When doors tilt diagonally or rub against one another in the centre, horizontal adjustment is required. This is the most common reason people ask how do i adjust cabinet door hinges when dealing with newly fitted or heavily used cupboards.

Look at the hinge arm extending from the carcass plate towards the door cup. The horizontal adjustment screw is the one positioned closest to the front of the hinge arm.

• Turning clockwise: Moves the door edge towards the hinge side (increasing the gap between a pair of double doors).
• Turning anti-clockwise: Moves the door edge away from the hinge side towards the centre (closing the gap between double doors).

Trade tip: If the top of the door is leaning to the right, adjust the top hinge screw in one direction and the bottom hinge screw in the opposite direction to straighten the diagonal tilt.

Step 3: Depth Adjustment (Aligning Flush with the Carcass)

If your cupboard door does not sit completely flat against the cabinet frame when closed, or if the edge binds against the carcass when opening, depth adjustment will resolve the problem. The depth screw is usually located furthest back on the hinge arm.

1. Loosen the rear screw on the hinge arm slightly.
2. Slide the hinge arm forwards or backwards along its track. Moving it backwards brings the door closer to the cabinet, while pulling it forwards creates clearance.
3. Retighten the screw and test the door movement. Ensure there is a consistent 1 mm to 2 mm gap between the door and the carcass face to prevent rubbing.

Frequently Asked Questions

Why does my cabinet door keep dropping after adjustment?

If an adjusted door sags again quickly, the screw threads inside the cabinet carcass may be worn or stripped. You can remedy this by inserting a wooden matchstick with PVA glue into the hole before re-driving the screw, or by fitting threaded metal repair plates.

Do these adjustments work on soft-close hinges?

Yes. Standard and soft-close concealed hinges share the same fundamental 3-way adjustment mechanism. The integrated soft-close piston simply dampens the closing motion and does not affect the physical alignment screws.
