Can I Shorten The Length Of Venetian Blinds?

Sometimes when we purchase things, we end up with something that doesn’t quite fit right. One of those things may be the blinds we just bought. They were the right fit for the width, but maybe they are too long and so there is too much blind gathered at the bottom blocking the ability to fully enjoy the window. However, you are able to shorten the blind’s length so that it fits your window better.

Things you will need:

  • The too long blinds
  • Scissors
  • Measuring tape
  • Chair or stool (to reach the top of the blinds)
  • Screwdriver
  • Tweezers
  • Pen and paper


First of all, you will want to be sure that you have the right measurements. It is important that you don’t take off too much and be left with blinds that are now too short. So, while the blinds are still up in the window let them down past the window, so you can determine how much excess there is. Count how many slats there are after the window ledge and write it down on your paper. Also, use the measuring tape and find the length of the window and write it down. This will help you to be sure of a more accurate length.

Next, you will need to remove the blinds. Be sure to exercise caution if you are using a chair or stool to reach the top of the blinds. Determine what type of screwdriver you need by looking at the screws. Once down, lay they blinds flat on the floor and unscrew the ends where the strings are. Undo the knot and begin to remove the excess slats. Be sure to look at the paper where you wrote how many you need to take off and then measure the blinds once those have been removed to be sure you didn’t take off too many or too little. Once you have the desired slats removed, reattach the base rail using the tweezers (if needed) to pull the strings back through. Cut any access string off and tie a knot at the end so that the base rail doesn’t fall off.

Lastly, re-install the blinds and test them to be sure that you reattached everything correctly and that the length is good. You will want to be sure that the adjusting cord isn’t pulled until you have everything leveled off or it may cause them to become crooked. Just put the bottom part of the blinds on the window ledge so you can determine that you tied off each string evenly. If you find that a string is too long, it is an easy fix to untie the know and knot it up further. If a string is too short, you may end up having to take the blinds down and remeasure everything so you don’t end up with crooked blinds. In the end, you can always call a professional like Cover Your Windows to help you with the shortening of your blinds.
