How To Adjust Bamboo Blinds

Bamboo blinds that are too long or too wide don't always need replacing. Bamboo blinds offer a practical and economical solution to privacy, and they are often tailored to fit the window. However, custom blinds cost more than buying them, you can make your own custom-blinds by trimming them. Here are tips to trim bamboo blinds.

Prepare to Work

For this project, you need:

  • work gloves
  • safety goggles
  • tape measure
  • tack cloth
  • masking tape
  • marker
  • metal file
  • sandpaper
  • wire snips
  • pliers
  • electric saw or hacksaw

Choose an inside mount or an outside mount. To measure an outside mount, measure the window frame width, and add two inches. Measure an inside mount on the window top, middle, and bottom. Use the smallest of the measurements as a guide when you trim them, and add two inches to the sides.

Trim the Headrail

Remove the headrail and the end cap, then tuck in the wiring with pliers, or tape them down to prevent injury. Mark the blind width on the headrail, then cut the line with a table saw or hacksaw.

Use sandpaper to smooth the edges of wood headrails, and smooth edge edges of metal headrails with a metal file. Remove sand dust using a tack cloth.

Adjust the Length

Remove binding on the blind edges, if it is present. Roll out the shades on a flat surface, and mark the desired length. Apply masking tape to the edges and ends of the blinds to prevent chipping, then add more masking tape below the line adding four inches. 

Add a second layer of tape above the line. Keep the blinds in place in the center using masking tape or rubber bands, if needed. Use the wire snips to make the cut across the bottom line keeping below the bottom line. 

Trim one layer at a time to reduce fraying, and ensure the edges stay even. Measure each slat after cutting it to check for evenness with the headrail.

Remove the tape, then move the slats from the binding strings until they reach the cut edge. Unwind the strings, tie them in knots on the end position, and add masking tape to the bottom. Remove the slotted base, then insert the new bottom length in it.

Adjust the Width

Transfer the window measurement to the blinds, and add masking tape to the edges. Roll up the blinds, and fasten them with string.

Mark the area to cut, and then use a hacksaw or electric saw to trim the width. You may only need to trim one side on irregular blinds.
