How to Adjust Hinges on Cupboard Doors

Over time, kitchen cupboards and wardrobe doors can begin to sag, catch on the frame, or sit unevenly alongside adjacent units. Fortunately, modern concealed cabinet hinges—often referred to as Euro-style or cup hinges—are engineered with built-in 3D adjustment mechanisms. With just a standard cross-head screwdriver and a few minor tweaks, adjusting hinges on cupboard doors is a straightforward task that can completely transform the look and function of your cabinetry.

Understanding the Anatomy of a Concealed Hinge

Standard 35 mm concealed hinges typically feature three distinct adjustment points. Before making any changes, it helps to understand what each screw controls on the hinge body and mounting plate:

• Side-to-Side (Horizontal) Screw: Found towards the front of the hinge arm, closest to the door. Turning this screw shifts the door left or right, correcting any uneven gaps between adjoining doors.
• Depth (In-and-Out) Screw: Positioned towards the rear of the hinge arm. This controls the distance between the cupboard carcass and the back face of the door, preventing rubbing or catching against the frame.
• Height (Vertical) Screws: Located on the mounting plate attached to the inside of the carcass. Loosening these screws allows the entire door assembly to slide up or down.

Step 1: Vertical Adjustment (Height)

If your cupboard door sits noticeably higher or lower than its neighbour, or catches on the top or bottom edge of the carcass, you need to adjust its vertical alignment.

1. Support the weight of the door with one hand (or place a small wedge underneath).
2. Slightly loosen the top and bottom screws on both mounting plates. Do not remove the screws entirely—just loosen them enough to allow movement.
3. Manually slide the door up or down to the correct height so it lines up with adjacent units.
4. Retighten the screws firmly, ensuring the mounting plate sits flat against the cabinet side.

Step 2: Horizontal Adjustment (Side-to-Side)

When doors have uneven vertical gaps or overlap awkwardly in the centre of a double unit, adjusting the horizontal screw will realign the door square to the carcass.

Turn the front adjustment screw on the hinge arm clockwise to move that corner of the door closer to the cabinet edge. Turn it anti-clockwise to push the door further into the centre opening. For a sagging door, adjust only the top hinge to draw the top corner back towards the cabinet frame.

Step 3: Depth Adjustment (In and Out)

If a door does not close flush, or if it binds against the cabinet edge when opening, you must correct the depth gap.

1. Loosen the rear screw on the hinge arm.
2. Gently pull the door forward or push it back towards the carcass. Aim for an even gap of around 1.5 mm to 2 mm along the entire front edge.
3. Tighten the rear screw firmly to lock the depth setting in place.

Adjusting Soft-Close Mechanisms

Many modern concealed hinges incorporate an integrated soft-close piston or clip-on damper. If the door bounces back or closes too slowly, check whether your hinge includes a tension switch or lever. Adjusting this setting alters the hydraulic resistance, allowing heavier doors to brake effectively and lighter doors to pull fully shut without hesitation.

Frequently Asked Questions

Why does my cupboard door keep dropping after adjustment?

If the door drops repeatedly, the screw holes in the cabinet carcass may have worn or stripped. Remove the mounting plate and inspect the screw holes. Inserting wooden dowels or specialised screw-hole repair plugs with a touch of wood glue will provide a fresh, secure fixing point for the mounting screws.

Do I need to adjust all hinges on a door at the same time?

For vertical height adjustments, yes—you must loosen all mounting plates simultaneously so the door can move freely. For horizontal and depth corrections, you often only need to adjust one hinge (such as the top hinge for a sagging door) to achieve the desired alignment.
