Why Adjusting Cordless Blinds Matters

Shortening cordless blinds isn’t just about aesthetics. Ill-fitted blinds can interfere with smooth operation, look awkward, and even pose safety risks, especially in homes with children or pets. Fortunately, modifying cordless window blinds is easier than it might seem—no need to replace them or settle for a poor fit. With the right tools and a step-by-step approach, you can resize cordless blinds to suit your windows perfectly.

Step 1: Gather Your Tools and Prepare the Workspace

Step 1: Gather Your Tools and Prepare the Workspace

Before starting the process of shortening cordless blinds, ensure you have the necessary tools on hand:


  • Measuring tape
  • Pencil or marker
  • Screwdriver
  • Sharp scissors or a utility knife
  • Lighter or fabric glue (optional, for cord adjustment)
  • Clean, flat surface for working

Measuring Your Blinds for Precision

The first step to resizing cordless blinds is taking accurate measurements. Fully extend the blinds and measure both the window frame and the blinds. Remember, it’s better to cut too little than too much—leave a small margin for error.

Step 2: Disassemble the Cordless Blinds for Modification

Step 2: Disassemble the Cordless Blinds for Modification

To modify cordless window blinds safely and effectively, you’ll need to disassemble parts of the blind mechanism.



  1. Remove the Bottom Rail and Slats
    Lay your blinds flat on a surface. Locate the bottom rail and use a screwdriver to carefully remove it. Most cordless blinds have small plugs at the bottom, which hold the cords in place. Gently pry these out to release the tension.
  2. Count and Remove Excess Slats
    Decide how many slats to remove based on your window measurement. Remove them one at a time to avoid damaging the blinds. Keep the extra slats for future repairs or adjustments.
  3. Secure the Cord
    After removing the extra slats, retie the cord and ensure it’s taut. If necessary, use a lighter or glue to seal the ends and prevent fraying.

Step 3: Reassemble and Test the Blinds

Once you’ve adjusted the length, it’s time to put the blinds back together.



  1. Reattach the Bottom Rail
    Thread the cord back through the bottom rail and secure it using the plugs you removed earlier. Double-check that everything is symmetrical for a neat appearance.
  2. Test the Functionality
    Hang the blinds back on the window and test their operation. Ensure they raise and lower smoothly. If you encounter resistance, check for misaligned slats or overtightened cords.
  3. Make Final Adjustments
    Trim any excess cord or material and tidy up th
    e edges. This ensures a polished, professional finish.
