How to Make and Hang Cupboard Doors: A DIY Guide

Building your own cabinet fronts is one of the most cost-effective ways to refresh a kitchen, utility room, or bespoke alcove unit. Whether you want a clean slab finish or a traditional framed look, knowing how to make cupboard doors properly ensures your project looks professional and functions smoothly for years to come.

1. Measuring the Carcase and Calculating Door Sizes

Before cutting any timber or board material, you must accurately determine your door dimensions based on the type of cabinet construction:

• Full Overlay: The door sits over the front edges of the carcase, leaving a small reveal (typically 2 mm to 3 mm per side). Subtract double the reveal width from the outer carcase width and height.
• Half Overlay: Used where two doors share a central divider (carcase upright). The door covers half the edge thickness.
• Inset Doors: The door sits entirely inside the carcase opening. Measure the internal opening and deduct a 2 mm to 3 mm expansion gap around the perimeter.

Always double-check that the carcase is square by measuring diagonally from corner to corner before finalising cut lists.

2. Choosing Materials and Cutting the Panels

When learning how to make cupboard doors, your choice of material dictates the build method:

• MDF (Medium Density Fibreboard): Excellent for painted finishes. Moisture-resistant (MR) MDF is ideal for kitchens and bathrooms because it resists warping.
• Plywood: Birch plywood provides strong structural integrity and attractive exposed edges if you prefer a modern, lacquered look.
• Solid Timber & Shaker Frames: A classic option consisting of vertical stiles, horizontal rails, and a central grooved panel (usually 6 mm veneered MDF or plywood).

Cut your boards using a plunge saw with a guide rail or a table saw fitted with a fine-toothed blade to prevent chip-out along the edges. Sand all faces and edges smooth before applying primer, paint, or clear lacquer.

3. Drilling for Concealed Cabinet Hinges

Standard Euro-style concealed cabinet hinges require a 35 mm circular recess (cup hole) drilled into the back of the door.

1. Mark the hinge centres, typically 100 mm from the top and bottom edges of the door.
2. Set the backset distance (the gap between the door edge and the edge of the 35 mm hole), usually between 4 mm and 5 mm depending on the hinge specification.
3. Use a 35 mm Forstner bit fitted to a pillar drill or a handheld drill with a depth-stop collar. Drill to a depth of 11.5 mm to 12.5 mm, taking care not to pierce the front face.
4. Insert the hinge cups into the holes, square the hinge arms using a straight edge against the door edge, and secure them with suitable wood screws.

4. Fitting Mounting Plates and Hanging the Doors

To hang the doors onto the carcase, attach the corresponding mounting plates inside the cabinet walls. For standard 32 mm system carcases, use the pre-drilled system holes located 37 mm back from the front edge. If working with bespoke units, mark the plate positions to match your door hinge centres exactly.

Once the plates are secured, clip or slide the hinge arms onto the mounting plates. Modern concealed hinges allow three-way adjustment via integrated screws:

• Lateral (Side-to-Side): Aligns vertical gaps between adjacent doors.
• Vertical (Height): Levels the door flush with the top and bottom of the carcase.
• Depth (In/Out): Ensures the door sits flat against the cabinet face without binding.

5. Adding Handles and Final Fittings

Finish your installation by fitting handles or knobs. Use a drilling template to ensure consistent placement across all cupboards. To prevent loud slamming and protect painted surfaces, stick small silicone buffer pads to the internal corners of each door.

Frequently Asked Questions

How many hinges do I need per cupboard door?
Doors under 900 mm in height and under 5 kg generally require two hinges. For taller doors (up to 1500 mm) or heavier materials, fit three hinges. Doors over 2000 mm often require four or five hinges to prevent bowing.

What is the standard drill bit size for cabinet hinges?
The standard concealed kitchen hinge cup requires a 35 mm Forstner bit. Smaller compact hinges occasionally require a 26 mm bit, so always check your hardware specifications before drilling.
