How to Measure Your Wardrobe Opening

Getting your measurements right is the most important step. Here's exactly how to do it.

IMPORTANT

The One Rule That Matters Most

You are measuring the wall OPENING — not the existing doors, not the track.

Getting this wrong is the #1 cause of order mistakes.

BEFORE YOU START

What You Need

Steel tape measure
Pencil & paper or phone notes
A second pair of hands for wide or tall openings

HOW TO MEASURE

The Right Way to Measure

Take four measurements across the full wall opening. Keep every number in millimetres.

RECORDING YOUR NUMBERS

  • All in millimetres — enter these 4 numbers when selecting your size range online.

CHECK BEFORE YOU ORDER

Common Mistakes to Avoid

A quick final check before ordering can prevent sizing problems and installation delays.

01

Measure the opening — not the doors

Always measure the full wall opening, not the existing doors, frame face, or track only.

02

Take both width and height readings

Measure the top and bottom width, plus the left and right height, rather than relying on a single reading.

03

Use millimetres only

Enter every measurement in millimetres so your selected size range matches correctly when ordering online.

04

Check for uneven floors or walls

If the opening is out of square, record the larger width and the smaller height before selecting your size range.

Depth check: Ensure you have enough clear internal depth for your chosen track system before ordering.

HOW TO INSTALL

Sliding Wardrobe Doors — Quick Reference

Around 30 minutes per opening. No trade experience required.

WHAT YOU'LL NEED

Tools

  • Power drill / driver
  • Phillips screwdriver
  • Measuring tape
  • Silicone gun
  • Spirit level

INCLUDED IN YOUR PACK

Everything for the fit

  • Top track & bottom track
  • Sliding doors, ready to install
  • Screws, silicone, end caps, door stops
  • Rubber buffer strip
Fitting the top track of a sliding wardrobe door opening
STEP 1

Fit the Top Track

  1. Attach the end caps to both ends of the track.
  2. Run a bead of silicone along the underside of the track.
  3. Hold the track level against the top of the opening, aligned with the frame.
  4. Screw in at both ends first, then the middle (add extra screws every 500mm if the opening is wider than 2400mm).
  5. Leave space at both ends for door stops.

Tip: pre-drill your screw holes in the track first — it keeps the track stable while you screw it in.

Fit the Bottom Track
STEP 2

Fit the Bottom Track

  1. Clean the floor so it's free of dust and debris.
  2. Attach the end caps to both ends of the track.
  3. Run silicone along the underside, covering both wheel channels.
  4. Position the track directly below the top track, wide side facing the front, then fix in place.

Tip: on carpet, fit a floor batten first so the track sits on a flat, solid surface.

STEP 3

Hang the Doors

  1. Check the rubber buffer strip is fitted along the door edge and trimmed to length.
  2. Lift the top of the door into the top track first, then lower the bottom wheels onto the bottom track.
  3. Fit the door stops — one on the front track, one on the back — so doors can't slide the wrong way.
  4. Adjust the wheels with a screwdriver until the door sits flush and doesn't scrape the track.
  5. Slide the doors back and forth to check they move smoothly.

Tip: always lift doors in and out vertically — never drag them sideways by the frame, this can separate the panel.

FINAL CHECK

Common Mistakes to Avoid

  • Skipping the silicone bead under the tracks — this stops movement and rattling over time.
  • Fixing the bottom track before checking the floor is clean and level.
  • Forgetting to leave space at the ends of the top track for door stops.
  • Dragging doors sideways instead of lifting them in and out.
  • Not adjusting the wheels — doors that scrape or sit unevenly usually just need a wheel height tweak.

THAT'S IT

Installation complete.

Once the doors slide smoothly and sit flush when closed, you're done — enjoy your new wardrobe.
