How to Put Hinges on Cupboard Doors

Fitting new doors to kitchen cabinets or bedroom wardrobes is one of the most effective ways to refresh a room, but getting the hanging right requires precision. Whether you are building units from scratch or replacing worn-out fittings, understanding how to put hinges on a cupboard door ensures smooth movement, flush alignment, and long-term durability. Concealed hinges (often called Euro-style hinges) are the trade standard for modern cabinetry, offering a clean appearance alongside multi-directional adjustment.

Essential Tools and Hardware

Before beginning your installation, gather the correct tools to ensure neat, accurate work. Standard concealed hinges require a specific pocket recess cut into the back of the door to house the hinge cup.

• Concealed hinges and mounting plates: Ensure you have the correct crank type for your unit (full overlay, half overlay, or inset).
• 35 mm Forstner bit: Required to bore the flat-bottomed recess for the hinge cup without piercing through the front of the door.
• Drill and pilot drill bits: A 2 mm or 2.5 mm bit prevents timber or MDF from splitting when inserting wood screws.
• Combination square and tape measure: Vital for consistent marking.
• Pozi screwdriver: For securing fixing screws and making fine adjustments.

Measuring and Marking the Hinge Centres

Accurate marking is the most critical stage when learning how to put hinges on a cupboard door. If the hinges are misaligned, the door will bind against the cabinet carcase or hang crookedly.

1. Determine vertical placement: As a standard rule of thumb, hinge centres are positioned between 75 mm and 100 mm from the top and bottom edges of the door. For taller pantry doors or heavy wardrobe doors, add a third or fourth hinge spaced evenly between the top and bottom fittings.
2. Set the edge distance (drilling margin): Mark the centre point for the Forstner bit. For most standard 35 mm concealed hinges, the edge of the drilled cup must sit roughly 4 mm to 5 mm from the door edge, placing the centre point of your drill bit at 21.5 mm to 22.5 mm from the outer edge. Always verify the specific drilling margin recommended for your hinge model.

Drilling the 35 mm Hinge Recess

Concealed hinge cups require a flat-bottomed hole, typically drilled to a depth of around 11.5 mm to 12.5 mm. Because standard cupboard doors are usually 18 mm thick, care must be taken not to drill too deep.

Fit your 35 mm Forstner bit into a pillar drill or a steady handheld drill. If using a handheld drill, wrap a piece of masking tape around the bit shank to act as a visual depth stop. Hold the drill perfectly vertical and bore the hole slowly, clearing wood shavings regularly to check depth. Once drilled, test-fit the hinge cup to confirm it sits flush with the rear face of the door.

Fitting the Hinges and Mounting Plates

With the recesses prepared, you can fix the hardware in place:

1. Secure the hinge cups: Place the hinges into the bored holes. Lay a straight edge or ruler against the rear edge of both hinge arms to ensure they are aligned parallel to one another. Mark the small screw holes on either side of the cup, drill shallow pilot holes, and drive in the fixing screws.
2. Mount the plates inside the carcase: Standard UK cabinetry utilises the 32 mm system. Measure and mark the corresponding plate positions on the inside of the cabinet wall. For a standard overlay door, the mounting plate screw holes are typically set 37 mm back from the front edge of the cabinet side panel.
3. Hang the door: Offer the door up to the cabinet. If using clip-on hinges, snap the hinge arms directly onto the mounting plates. For slide-on hinges, slide the hinge arm over the plate screw and tighten it securely.

Fine-Tuning Door Alignment

Once hung, modern concealed hinges allow you to adjust the door in three directions using the adjustment screws on the hinge arm:
