How to Install Cabinet Hinges: Step-by-Step Guide

Fitting cabinet hinges might seem daunting if you have never drilled into a fresh door, but with the right tools and systematic measurements, you can achieve a factory-standard finish. Whether you are assembling bespoke cupboards or updating existing kitchen doors, understanding the fundamentals of proper hinge installation ensures smooth movement, flush alignment, and long-term durability for your cabinetry.

Choosing the Right Hinges for Your Project

Before drilling begins, it is essential to identify the correct hardware configuration. In modern joinery, concealed cup hinges (often called Euro hinges) are the industry standard due to their clean appearance and multi-directional adjustability.

• Full Overlay: The door completely covers the front edge of the cabinet carcass. This is standard for modern modular units.
• Half Overlay: Two doors share a single central divider, each covering half the carcass edge.
• Inset: The door sits entirely inside the cabinet opening, flush with the front frame.
• Soft-Close Mechanisms: Built-in hydraulic dampers that catch the door and close it silently without slamming.

Tools and Materials Required

Gathering the correct joinery tools beforehand will prevent costly mistakes during the installation process:

• Tape measure and steel rule
• Pencil or fine-point marking awl
• Combination square or set square
• Cordless drill and driver bits
• 35 mm Forstner drill bit (standard cup diameter)
• 2 mm drill bit (for pilot holes)
• Concealed hinges and mounting plates with appropriate wood screws

Step-by-Step Concealed Hinge Installation

Follow these steps to ensure accurate placement and a secure fix on standard 18 mm or 16 mm cabinet materials.

1. Mark the Cup Hole Centres

As a general rule of thumb, hinge centres are positioned 100 mm from the top and bottom edges of the cabinet door. Measure 100 mm in from the edge, then mark the distance from the side edge to the centre of the cup hole (the drilling tab distance is typically between 4 mm and 6 mm, resulting in a centre point roughly 21.5 mm to 22.5 mm from the edge). Always check your hinge plate specifications.

2. Drill the 35 mm Cup Holes

Attach your 35 mm Forstner bit to your drill. Set your depth stop to match the depth of the hinge cup (usually 11.5 mm to 12.5 mm). Drill steadily, keeping the drill perpendicular to the door face. Clear the wood shavings regularly to avoid overheating and ensure a flat-bottomed recess.

3. Mount the Hinges to the Door

Insert the hinge cups into the drilled recesses. Use a straight edge placed across both hinge arms to ensure they are perfectly square to the door edge. Drill shallow 2 mm pilot holes into the screw locations, then secure the hinges with wood screws.

4. Fix the Mounting Plates to the Carcass

Measure the corresponding heights on the inside of the cabinet carcass. In standard 32 mm cabinet systems, mounting plates are typically fixed 37 mm back from the front edge of the carcass. Drill pilot holes and secure the mounting plates firmly with screws.

5. Hang and Connect the Door

Offer the door up to the cabinet. For clip-on hinges, simply align the hinge arm with the mounting plate and press until you hear a solid click. For slide-on hinges, slide the hinge arm over the plate screw and tighten it securely into position.

Adjusting and Aligning Cabinet Hinges

Once the hinges installation is complete, concealed hinges allow three-way adjustment to eliminate uneven gaps and ensure smooth operation:

• Side-to-Side (Lateral): Turn the front screw on the hinge arm to move the door left or right, correcting vertical gaps between adjacent doors.
• Height (Vertical): Loosen the top and bottom screws on the mounting plate to slide the entire door up or down, then re-tighten.
• Depth: Adjust the rear screw on the hinge arm to bring the door closer to or further away from the cabinet carcass face.

Frequently Asked Questions

How many hinges do I need per cabinet door?

Doors up to 900 mm tall and under 4–5 kg usually require 2 hinges. Doors between 900 mm and 1600 mm (or 6–9 kg) require 3 hinges, while taller pantry or wardrobe doors may require 4 or 5 hinges to prevent warping.

Why is my cabinet door rubbing against the frame?

Rubbing usually indicates that the lateral or depth screws need adjustment. Check that the door sits square in the opening and use the front adjustment screw on the hinge arm to create an even 2 mm to 3 mm perimeter reveal.
