How to cut horizontal blinds that are too wide?

Most home improvement stores sell horizontal blinds in stock sizes. If your window is not the right size for your pre-made blinds, trim them yourself without spending money to buy custom blinds. As a rule, the store will cut them, but if you want to do it yourself, or if you are moving blinds from a larger window to a smaller one, you can do it at home with the help of some tools. This also includes trimming the handrail and roller.

Cut the handrail

Measure the width of the handrail and the window where the blinds will be installed. Subtract the width of the window from the width of the rail. This is the amount you need to cut.

If it is more than 2 inches long, divide it in half to cut off 1/2 of the excess width on each side. If it’s smaller, you can cut it all off on one side.

  • Measure the handrail and make a mark on one end or a mark on each end where you will cut.
  • Take out the stiffeners that are at the end of the rail. These are the pieces of metal that hold the handrail in a square position.
  • Cut the handrail according to the gum markings. If the metal bends when you cut it, bend it back into place when you finish cutting. Insert the stiffeners back into the ends.

Finishing the louvers

Align the strips so that they are stacked evenly. Make the ends flush. Include the bottom rail, even if it is thicker than the slats.

Wrap a rubber band tightly around the louvers at each end to keep them flat.

  • Measure as you did in the first section to determine how much to cut from the louvers. Unlike railing cuts, always cut off 1/2 of the measurement from each end of the louver, no matter how small the cut is. This is to ensure that the strings that control the louvers remain evenly spaced on each side after the cut is complete. Apply painter’s tape to the mowing line of the cut, as in step one, so that the louvers will not break during the cutting process. Add the cut fishing line to the tape.
  • Place the strips on the table saw so that the blade is at the mowing line of the cut on the painter’s tape. Use a saw with fine teeth designed for finished wood. If there is metal on the louvers, use a carbide blade. Cut the blinds, moving them slowly and carefully. Consider the bottom slat when cutting. Even though it is thicker, it can be cut with a saw.
  • Remove the tape and elastic bands. If uneven edges are left, sand them with fine-grit sandpaper 150.
