How to Fit Sliding Wardrobe Doors: A Practical Installation Guide

August 25, 2026

Installing sliding panels is an efficient way to maximise bedroom floor space whilst creating a neat, modern finish. Whether you are building built-in storage from scratch or upgrading an existing cabinet carcass, understanding how to fit sliding wardrobe doors correctly ensures smooth running, proper alignment, and long-term durability. This guide walks you through preparing the opening, securing tracks, mounting the running gear, and fine-tuning the final movement.

Essential Tools and Hardware Components

Before beginning the installation, ensure you have the correct wardrobe sliding door gear matched to your door weight and material thickness. A standard dual-track installation requires:

Top guide track and bottom running track
Bottom rollers (load-bearing running gear)
Top guide wheels or guide channel gliders
Soft-close dampers and track position stoppers
Spirit level, tape measure, and pencil
Drill, pilot bits, and appropriate wood screws
Hacksaw (for cutting aluminium tracks to length)

Step 1: Measuring and Cutting the Tracks

Accurate measurement is critical when learning how to fit sliding doors on a wardrobe. Top and bottom tracks must match the exact width of your wardrobe aperture.

Measure the interior width of your wardrobe frame at both the top and the bottom, as timber frames are rarely completely square.
Mark the top guide channel and bottom running track to length.
Cut the aluminium tracks neatly using a fine-toothed hacksaw, deburring any sharp metal edges with a metal file.
Pre-drill screw holes along the track channels every 400 mm to 500 mm if your tracks do not come pre-punched.

Step 2: Securing the Top and Bottom Tracks

The top track guides the doors vertically, while the bottom track carries the load. Both must sit perfectly parallel to prevent the doors from derailing or binding.

Fix the top guide track flush to the front edge of the wardrobe ceiling using suitable wood screws. Next, position the bottom track on the wardrobe floor directly beneath the top track. Use a plumb line or a long spirit level to ensure the vertical axis between the top and bottom channels is true before driving screws into the bottom track.

Step 3: Preparing the Door Panels and Running Gear

Lay your door panels flat on a clean, protected surface. Most systems require top guide wheels fixed near the upper corners and adjustable bottom rollers mounted on the lower edge.

Top Guides: Fasten the guide brackets into the upper corners of the door's rear face, typically set in 50 mm to 100 mm from each side.
Bottom Rollers: Mount the roller housings to the bottom corners. Ensure you have access to the height adjustment screw once the door stands upright.
Soft-Close Dampers: If using soft-close units, install the damper mechanisms into the top track and attach the corresponding activator pins onto the top edge of the doors.

Step 4: Hanging and Adjusting the Doors

So, how do you fit sliding wardrobe doors into the tracks once the hardware is mounted? Always start with the rear door panel first.

Lift the door at a slight angle, inserting the top guide wheels fully into the rear channel of the top track.
Swing the bottom of the door inward and lower the bottom rollers directly into the rear groove of the bottom track.
Repeat the process for the front door panel, fitting it into the front track channels.
Check the vertical alignment of each door against the wardrobe side walls. Turn the adjustment screws on the bottom rollers clockwise or anti-clockwise to raise or lower each side until the doors hang plumb.
Slide the doors to each end to test the soft-close engagement and tighten the track stoppers in position.

Frequently Asked Questions

How much overlap should sliding wardrobe doors have?

A standard overlap is between 25 mm and 50 mm per door. This prevents sightlines into the wardrobe through the gap between front and rear panels.

Why are my sliding wardrobe doors jumping the track?

Track jumping usually occurs if the bottom track is filled with dust or debris, if the tracks are not vertically plumb, or if the bottom rollers need height adjustment to maintain sufficient tension under the top track.
