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

August 25, 2026

Misaligned kitchen cabinet doors can make an otherwise pristine kitchen look untidy and tired. Over time, everyday use, heavy loads, and natural building movement can cause doors to sag, rub against the carcass, or sit at awkward angles. Fortunately, modern concealed hinges—often referred to as European or cup hinges—are engineered with built-in 3-way adjustment screws that make realigning them straightforward with just a standard screwdriver.

Understanding 3-Way Concealed Hinges

Before turning any screws, it helps to understand how a standard 35 mm concealed hinge works. These fittings allow for three independent axes of movement, meaning you can fine-tune the door without detaching it from the carcass:

Side-to-side (Lateral): Shifts the door horizontally across the cabinet face to correct gaps between adjacent doors or fix diagonal sagging.
Up-and-down (Height/Vertical): Raises or lowers the door relative to the cabinet top and bottom edges.
In-and-out (Depth): Moves the door closer to or further away from the cabinet carcass to ensure it sits flush with neighbouring panels.

Step 1: Diagnose the Alignment Problem

Close all the cabinet doors in the run and step back to observe the gaps. You will usually encounter one of three common issues:

The door hangs crookedly, leaving an uneven diagonal gap along the top or side.
The door rubs against the carcass frame or catches on an adjacent door when closing.
The top or bottom edge does not line up horizontally with neighbouring doors.

Step 2: Adjusting Side-to-Side (Lateral Screws)

If you are wondering, how do I adjust cabinet hinges when a door hangs at an angle, the lateral screw is your primary tool. This is typically the screw situated closest to the door cup on the hinge arm.

Turn the screw clockwise to push the top or bottom corner of the door towards the hinge side of the carcass.
Turn the screw anti-clockwise to push that corner away from the hinge side towards the centre of the unit.
If the door sags downwards towards the opening side, turn the lateral screw on the top hinge clockwise, or turn the bottom hinge screw anti-clockwise.

Step 3: Adjusting Door Height (Vertical Screws)

Height adjustment is controlled via the mounting plate fixed directly to the cabinet carcass. On standard base plates, this is achieved through elongated slotted screw holes.

Loosen the mounting plate screws on both the top and bottom hinges slightly—just enough to allow movement without the door falling.
Support the weight of the door and slide it upwards or downwards until the horizontal line aligns with adjacent panels.
Retighten the screws securely, taking care not to overtighten and strip the pilot holes in the chipboard or MDF carcass.

Step 4: Adjusting In-and-Out Depth

The depth adjustment screw is usually located furthest back along the hinge arm, away from the door panel. This screw controls how proud the door sits when closed.

Loosen the depth screw slightly on both hinges.
Push the door in or pull it out until the gap between the back of the door and the carcass edge is consistent (typically around 1 mm to 2 mm to prevent rubbing while retaining a clean seal).
Tighten the screw firmly to lock the hinge arm back into position.

Frequently Asked Questions

Do I need specialist tools to align cupboard doors?

In most cases, all you need is a standard cross-head (Pozi #2) manual screwdriver. Avoid using high-torque cordless drill drivers, as they can easily cam out and strip the delicate adjustment screw threads.

Why won't my cabinet door stay aligned after adjustment?

If a door continually slips out of alignment, the fixing screws in the cabinet carcass may have worn their screw holes loose. Check whether the mounting plate wobbles; if so, you may need to fill the existing hole with a wooden dowel or use specialist hinge repair plates.
