Double roller blinds — also called dual or day and night blinds — are a clever two-in-one solution that combines light-filtering and blackout fabrics on separate rollers. But if your blinds are too long, they can appear bulky, roll unevenly, or bunch at the bottom. Shortening them ensures both layers align perfectly and operate smoothly, maintaining their modern, streamlined look.
Before you begin
Because double roller blinds feature two separate fabric rolls housed within a single bracket, you’ll need to adjust both fabrics to keep the drop consistent. Begin by fully lowering each blind to assess how much needs to be removed. Measure carefully — leaving a 1–2 cm gap above the sill for clearance.
If your blinds have a cassette or motorised control, or you’re unsure how to remove them safely, it’s best to contact experts such as Double roller blinds with fitting service before making any adjustments.
Step-by-step guide to shortening double roller blinds
- Remove the blind from its brackets: Carefully lift the double roller unit out of its mounting clips, supporting both rollers evenly.
- Unroll both fabrics completely: Lay the blinds flat on a clean surface, with each fabric extended to its full drop.
- Remove the bottom bars: Slide or unclip the weighted bars from the lower hems of both blinds.
- Measure and mark the new length: Decide on the desired length and mark a straight cutting line for each fabric, leaving a small allowance (1–2 cm) to reattach the bottom bars.
- Trim the fabrics: Use a sharp pair of scissors or a rotary cutter to cut both fabrics cleanly and evenly. For blackout layers, take care not to damage the coated surface.
- Reattach the bottom bars: Slide or clip them back into place, ensuring the edges align perfectly.
- Reinstall and test: Refit the blind unit onto the brackets and test both rollers, checking that they move freely and stop at the correct point.
Common issues and troubleshooting
If one layer appears longer than the other, recheck your measurements — both fabrics must match exactly. Uneven rolling often means the fabric isn’t centered properly on the roller; unroll and realign if needed. For blinds with spring mechanisms, avoid overwinding, as this can affect the tension.
Should your blinds have enclosed cassettes or electronic components, a professional adjustment from Double roller blinds with fitting service is strongly recommended to maintain balance and prevent damage.
