How to Fit Sliding Wardrobe Doors

Two Parts:Preparing the SpaceInstalling the Tracks and Doors

Sliding closet or wardrobe doors usually come with all the running gear and tracks needed for installation. To fit the top and bottom tracks and insert the sliding doors, you will need to measure the space, cut the tracks to size, and screw them into place before you can fit the doors. You can complete this entire easy process in less than an hour with a little guidance.

Part 1
Preparing the Space

  1. Image titled Fit Sliding Wardrobe Doors Step 1
    Remove the old doors. If you want to install completely new sliding doors, then start by removing the old doors and tracks. Lift up on the old doors until the rollers come off the bottom track. Angle them forward as you lower the top guide away from the top track.

    Remove the old tracks. Unscrew the old tracks and pry them up if necessary. For wooden bottom tracks coated with paint, use a utility knife at the edge of the track. This will stop the adjacent paint from potentially peeling up with the track.[1]

    Clean up the area. Remove any leftover debris. Precision measurements are essential for proper installation.

    Install a floor liner. If the closet space has carpeting or a rug that sits right next to the door, you should install a floor liner.[2] These inexpensive liners fit beneath the bottom track. They keep carpeting or rugs from binding the door rollers.
    • If you decide to install a floor liner beneath the bottom track, set it in place before you measure to ensure accurate measurements.

    Measure the space for the doors. Before you even buy doors, measure the space because not all doors are created equal. Take a horizontal measurement from the edge of the left wall to the edge of the right wall. Take a vertical measurement from the floor (or liner) up to the top of the space.[3]
    • Since the height from one end of the closet to the other can differ, take the height measurement at the middle and each end of the opening. Use the smallest of the measurements.
    • Measure twice and write the measurements down to take with you.
    • If the top of your closet space has a fascia (a decorative, overhanging accent piece), then make sure you take your measurement behind the fascia where you will install the track.[4]

Part 2
Installing the Tracks and Doors

  1. Image titled Fit Sliding Wardrobe Doors Step 6
    Buy doors. Using your measurements, buy doors for the space. Most door sets come with corresponding tracks (typically made of aluminum) that you can cut to size. The actual rollers on the doors typically have an adjustable screw to change the lift of the roller. Look at the variance figures on the doors to ensure they’ll fit your space.
    • The combined width of the doors should equal the width of the space plus approximately 1”. This will give the doors 1/2” of overlap, ensuring you do not end up with a gap between the doors.[5]
    • If you buy tracks separately from the doors, remember that most tracks come sized for 1-3/8” thick doors.[6] Thicker doors may need special-sized tracks.

    Cut the tracks to size. You will likely need to trim the tracks that come with the doors down to size. Measure twice and cut once to ensure you don’t cut too much off the tracks.
    • The width of the closet opening can vary from top to bottom, so measure the width at both spots to ensure you cut each track to the proper length.[7]
    • Most tracks are aluminum. You can easily make the cut with a hacksaw or any type of electrical saw.[8]

    Install the bottom track. Set your bottom track in place. Then use the pre-drilled holes to screw the track down to the floor. If your space has carpeting over a concrete slab, then put a piece of masking tape on the carpet before setting down the track. Mark the tape by poking a pen or pencil through the pre-drilled hole. Then use the marking on the tape to drill your pilot hole through the carpet into the slab before screwing the track down.[9]

    Install the top track. Since the rollers on the doors do not align perfectly with the guide on the top track, you must install the top track slightly farther back than the bottom track on most doors. This adjustment is tiny—approximately 5/16”.[10] The exact adjustment will vary based on your chosen doors, so follow the instructions with your doors carefully when screwing the top track into place.

    Fit the rear sliding door. Since the doors will overlap slightly, you will need to fit the rear door before the front door. To install, lift the top of the door into the rear track guide at a slight angle, and then tilt the bottom into place. Ensure that the rollers properly align in the rear bottom track.[11]
  6. Image titled Fit Sliding Wardrobe Doors Step 11
    Fit the front sliding door. Once you have the rear door in place, use the same process as in the previous step to install the front door.
  7. Image titled Fit Sliding Wardrobe Doors Step 12
    Adjust the rollers. The rollers at the bottom of each door typically have an adjustable screw to slightly raise the door. Adjust the door height to raise the door, which will give a bit more clearance for the rollers and keep the wheels from binding with carpet.[12]
    • Some designs will snap the rollers into place along the track as you adjust the height screw.[13] Other sliding door designs may have a small switch on the roller assembly that locks the roller into the bottom track.[14] Follow the directions on your specific doors.


  • Do not over tighten the screws on the tracks as it can warp the aluminum.
  • Fit a block into each side of the top track when sawing to prevent it deflecting.
  • Use silicon spray on the bottom track to get a smooth, quiet glide.


  • Take care not to drill into anything electrical!
  • Get help lifting solid doors into the tracks to avoid injury.
