Achieving a seamless fit and smooth operation for sliding wardrobe doors on precise measurement and meticulous installation. Whether you’re a trade professional, developer, or DIY enthusiast, adhering to best practices ensures a flawless finish and enduring performance.
Inaccurate measurements or improper installation can lead to misalignment, operational difficulties, and diminished durability. This guide offers step-by-step instructions on measuring and installing sliding wardrobe doors, ensuring a professional-quality outcome every time.

1. Tools and Materials Required
Before commencing, gather the essential tools and materials:
- Tape measure – For precise measurements.
- Spirit level – Ensures accurate alignment.
- Drill and screws – For securely fixing tracks.
- Pencil and ruler – For marking reference points.
- Screwdriver – For securing fittings and adjustments.
- Plumb line – To check vertical alignment.
- Track system – Supplied with your sliding wardrobe doors.
- Sliding wardrobe doors – Customised to your measurements.
Having the right tools ensures a smooth, efficient installation process.
2. How to Measure for Sliding Wardrobe Doors
Step 1: Measure the Height of the Opening
- Positioning: Measure the total height of the opening from floor to ceiling at the recommended 610mm from the back wall to allow enough space for internal fittings.
- Multiple Measurements: Take three height measurements—left, centre, and right.
- Select the Smallest Measurement: Floors and ceilings may not be perfectly parallel; using the smallest measurement ensures the doors fit without obstruction.
Step 2: Measure the Width of the Opening
- Wall-to-Wall Installation: For installations without end panels, measure the width at two points: top (D) and bottom (E).
- Wall-to-End Panel Installation: If the wardrobe fits between a wall and an end panel (e.g., a doorway or window opening), include the end panel in your measurements.
- Select the Largest Measurement: Walls may not be perfectly parallel; using the largest measurement ensures proper door overlap.
Step 3: Check for Level and Plumb
- Floor and Ceiling: Use a spirit level to ensure both are even.
- Walls: Check vertical alignment with a plumb line.
- Adjustments: Use shims or packing materials to correct any uneven surfaces before installation.
Additional Tips:
- Assistance: Enlist help when measuring, especially for height, to ensure accuracy.
- Obstructions: Identify and address any obstructions like skirting boards, coving, or radiators. Remove them or build around them to create an unobstructed opening.
- Measurement Accuracy: Ensure you provide the smallest height and largest width measurements to the manufacturer for a perfect fit.
3. Preparing for Installation
Clear the Area
- Remove Existing Doors: Take out any current doors or obstructions.
- Clean the Space: Ensure the opening is free from dust and debris for smooth track installation.
Install the Top Track
- Positioning: Place the top track against the ceiling or pelmet, 2mm from the front edge of the wall liner or end panel.
- Alignment: Use a spirit level to ensure proper alignment.
- Securing: Drill 5mm holes 150mm from each end and at approximately 1000mm intervals. Secure the track with screws at the recommended points.
Install the Bottom Track
- Alignment: Ensure the bottom track aligns perfectly with the top track for smooth door operation.
- Securing: Depending on the floor surface, fix the bottom track in place with adhesive or screws, ensuring it is level to prevent the doors from rolling unintentionally.
4. Installing the Sliding Wardrobe Doors
Step 1: Insert the First Door Panel
- Positioning: Lift the door into the top track at an angle.
- Placement: Lower it into the bottom track, ensuring the rollers are correctly positioned.
Step 2: Insert the Second Door Panel
- Repetition: Repeat the process with the second door.
- Functionality Check: Ensure both doors are aligned and slide smoothly.
Step 3: Adjust the Doors for Perfect Alignment
- Roller Adjustment: Use the adjustment screws on the rollers to fine-tune the height.
- Overlap Check: Ensure the doors overlap correctly and close smoothly.
- Track Positioning: Make small adjustments to the track positioning if necessary.
5. Common Installation Issues and How to Fix Them
Issue: Doors Are Not Sliding Smoothly
- Debris: Check for debris in the track and clean it out.
- Alignment: Ensure the tracks are level and aligned correctly.
- Roller Adjustment: Adjust the roller screws for smoother operation.
Issue: Doors Are Not Closing Properly
- Frame Squareness: Check if the frame is square using a spirit level.
