How to Put Hinges on Cabinet Doors: A Step-by-Step Guide

Hanging new cabinet doors or replacing dated hardware is one of the most effective ways to refresh a kitchen or utility space. While the process may seem daunting, understanding how to put hinges on cabinet doors properly comes down to accurate measurements, correct hole drilling, and careful alignment. Standard European concealed cup hinges offer excellent durability and full 3D adjustability, making them the industry standard for modern cabinetry.

Essential Tools and Materials

Before beginning your installation, gather the right equipment to ensure clean, accurate results:

• Concealed cup hinges and matching mounting plates
• 35 mm Forstner drill bit or specialised hinge drilling jig
• Tape measure and combination square
• Pencil or fine-point marking tool
• Cordless drill and appropriate pilot drill bits
• Short wood screws or pre-drilled euro screws
• Screwdriver (usually Pozi PZ2)

Step 1: Measuring and Marking Cup Hole Positions

Concealed hinges sit within a recessed circular pocket routed into the back of the door. The typical standard is to position hinges approximately 70 mm to 100 mm from the top and bottom edges of the door. For taller doors (above 900 mm), a third hinge centred between the two is recommended to prevent warping.

Use a combination square to draw a reference line parallel to the door edge. For standard 35 mm hinges, the distance from the edge of the door to the edge of the cup hole (often referred to as the cup reveal or drilling distance) is usually between 3 mm and 5 mm. Combined with the 17.5 mm radius of a 35 mm cup, the centre point of your drill bit should generally be marked at 21.5 mm to 22.5 mm from the door edge. Always verify the manufacturer's specification sheet before marking.

Step 2: Drilling the Hinge Cup Recesses

Using a standard twist bit will tear the wood fibres; always use a sharp 35 mm Forstner bit or a dedicated drilling jig for this task.

1. Set depth carefully: Standard concealed hinge cups require a depth of approximately 11.5 mm to 12.5 mm. Wrap masking tape around your drill bit as a visual depth stop to avoid drilling straight through the front of the door.
2. Drill straight: Keep the drill perpendicular at a 90-degree angle to the workpiece. Apply firm, steady pressure at a moderate speed to cut a clean flat-bottomed hole.
3. Clear debris: Vacuum or blow away wood shavings to ensure the hinge cup seats fully flush into the timber.

Step 3: Fitting the Hinges to the Door

Insert the hinge cups into the freshly drilled pockets. To ensure the hinge arms are perfectly square to the door edge, lay a straight edge or ruler across both hinge bodies before fastening them in place. Mark the screw fixing holes on either side of each cup, drill shallow 2 mm pilot holes, and fasten the hinges securely with the provided wood screws.

Step 4: Installing Mounting Plates on the Carcase

Standard flat-pack carcases feature a 32 mm system drilling pattern along the inner side panels. If your cabinet already has these holes, mounting plates can be secured directly using euro screws or standard wood screws. The standard setback from the front carcase edge to the centre of the mounting plate screws is typically 37 mm.

If you are retrofitting doors to an un-drilled cabinet, support the door against the carcase at your desired height, mark the plate positions onto the inner wall, drill pilot holes, and screw the mounting plates firmly into place.

Step 5: Hanging and Fine-Tuning the Door

Clip or slide the hinge arms onto the carcase mounting plates until they engage firmly. Modern concealed hinges feature three adjustment screws on the arm:

• Side adjustment: Moves the door left or right to set consistent gaps between adjacent doors.
• Height adjustment: Located on the mounting plate, this shifts the door vertically.
• Depth adjustment: Moves the door closer to or further from the carcase to ensure it sits flat when closed.

Frequently Asked Questions

Can I install concealed hinges without a drilling jig?

Yes. A combination square, a sharp pencil, and a 35 mm Forstner bit are sufficient for accurate manual layout, provided you take time to double-check your centre points.

Why won't my cabinet door close completely flush?

This is usually caused by incorrect depth adjustment on the hinge arm, hinge cups not sitting deep enough in their recesses, or the mounting plate being positioned too far back inside the carcase.
