Why you might need to shorten electric blinds
Electric blinds are a sleek, modern solution that brings comfort and convenience to your home or office. Whether you’ve moved them to a new window or found that they extend slightly too far, adjusting the length can improve their appearance and ensure smooth operation. Because they contain motors and wiring, however, shortening them requires precision and care.
Before you begin
Electric blinds operate using a motorised roller or tension system, often controlled by a remote or smart device. Shortening these blinds isn’t as simple as trimming fabric — you’ll be working around electrical components and need to maintain the correct tension for safe use. Before attempting any changes, fully lower the blind and measure the excess length.
If your blind includes integrated wiring, a cassette housing, or built-in sensors, it’s strongly recommended to contact professionals such as Electric blinds with fitting service before attempting modifications.

Step-by-step guide to shortening electric blinds
- Disconnect the power: Unplug or turn off the power supply to avoid accidental activation. For hardwired systems, switch off the circuit at the mains.
- Remove the blind from its brackets: Carefully lift the blind out of the mounting brackets while supporting the roller to prevent strain on the motor.
- Expose the fabric: Unroll the blind fully on a flat surface to see how much needs to be removed.
- Detach the bottom bar: Slide or unclip the weighted bar from the hem pocket.
- Mark and trim the fabric: Measure the new desired length and use a sharp blade or scissors to cut the fabric evenly, leaving a small allowance (about 2 cm) for reattaching the bar.
- Refit the bottom bar: Slide it back into place and check that it’s straight and secure.
- Reinstall and test: Refit the blind to its brackets, reconnect the power, and test the motor to ensure the fabric rolls smoothly to the new length.
Common issues and troubleshooting
If the blind stops short or rolls unevenly, recalibrate the motor limits according to the manufacturer’s instructions. For systems with smart controls, re-pair the remote or app after adjustment. Uneven rolling usually means the fabric isn’t aligned perfectly on the roller — unroll and refit it carefully.
Because electric blinds vary in design, complex systems should only be adjusted by professionals offering Electric blinds with fitting service to prevent electrical damage or motor failure.
