Vertical bind louvres come in many different designs and styles. (vertical yellow background image by .shock from

Vertical window blinds provide a decorative window covering that can range from plain white to complicated custom designs. Vertical window blinds can have the headrail and louvres cut to fit virtually any window or door opening. Vertical blinds have installation instructions for two different mounting styles. Typically windows use the inside mounting style, while sliding doors use the outside mounting style to attach to the ceiling or just above the door. Use mild soap and water solution to clean vertical blind louvres.

  1. 1

    Layout the end-mounting brackets with a tape measure. For the inside-mount style brackets, make a pencil mark 4 inches from the inside top edge of the window casing towards the centre. For outside-mount style brackets, make a pencil mark on the centre of the headrail and the window casing. Measure from the headrail's centre line to the end and subtract 3 inches. Place a pencil mark on the top of the window casing this measurement from the centre line in each direction.

  2. 2

    Space the centre-mounting brackets evenly between the end-mounting brackets. Mark these spots on the window casing with a pencil.

  3. 3

    Install the mounting brackets in line with the layout marks. Mount inside-brackets 1 inch in from the wall. Mount outside brackets 2 inches above the window casing. Use plastic wall anchors when attaching the brackets to drywall and Phillips head screws when attaching the brackets to a backing plate or stud.

  4. 4

    Lift the headrail up to the mounting brackets. Keep the headrail's front edge on the brackets and lower the rear side, forming an angle. Hold the headrail's front edge in the bracket clips and push up on the rear of the headrail until it snaps into the brackets. Verify each bracket has snapped into place.

  5. 5

    Measure from the louvre clips to the window sill or the door threshold and subtract 1/2-inch. Plastic louvre-blade clips, found under the headrail, have a two-part prong. One of these prongs has a small hook that the louvre blade connects to.

  6. 6

    Cut the louvre blades with a hacksaw or scissors at the measured length.

  7. 7

    Install a louvre blade in each louvre-blade clip. Keep the pattern uniform.

  8. 8

    Attach the tension pulley to the pull string. The weighted pulleys hang from the pull strings and help prevent them from tangling.

  9. 9

    Open and close the blinds while watching the bottoms of the blinds. If a blind drags then cut it with a pair of scissors.

Tips and warnings

  • If needed, use a flat screwdriver to remove the headrail from the mounting brackets.
