How to Cut Roller Blinds

Updated February 21, 2017

Window blinds come in many types that roll or pull down to cover window; some are pleated and use a pull cord. Each type of shade is mounted on a bracket near the top of a window. These blinds can be reused in a different window but may not be the correct width and need to be cut to size. You can cut a roller blind by first determining the width that is needed for the blind.

Measure the width of the window opening with a tape measure.

Transfer the measurements to the window shade and make a mark with a pencil where you will need to cut the blind.

Roll out the blind and place it on a flat surface, such as the floor or a workbench.

Use a tape measure to measure the amount of the fabric shade that needs to be cut off of one end.

Make two to three marks down the length of the shade with a pencil.

Place the straight edge over the marks you made and cut the fabric along the straight edge with a utility knife.

Close the shade and cut the end of the head rail and valance, if necessary, with a hacksaw along the cut end of the fabric shade.

Remove the cap from the small end of the blind with pliers and then place the cap on the end of the newly cut shade.

Mount the shade in the window to complete the project.


Trim kits can be purchased; they include a tape measure and utility knife.


Cutting the fabric of the shade without using a straight edge may leave a cut that is not straight.
