Measuring for roller blinds side by side with cord pull

Roller blinds side by side are a great option for wide windows. On our cord pull blinds the fabric runs the full width of the blind, so the two blinds can hang close together. However, as they are made from natural materials and roll up by the cord, they may roll slightly unevenly and shift from side to side so there needs to be a small gap between each blind. This is part of their natural character.
Step 1 – Measure the width

Using a metal tape measure, measure the full width of the recess at the top, the middle and the bottom of the window. Make a note of the smallest measurement.

Step 2 – Calculate the width of each blind

Deduct 2cm from the smallest width for clearance in the recess. Then deduct a further 1cm for each gap between the blinds, so they can be rolled up and down separately without touching. Two blinds have one gap, three blinds have two gaps, and so on. Divide the result by the number of blinds to get the finished width of each blind. If your window has a central frame or mullion, or you would like blinds of different widths, simply split the total width the way you prefer. Just remember to deduct the 2cm and 1cm for each gap first.

Example with two blinds:
183cm – 2cm – 1cm = 180cm ÷ 2 = Finished width of each blind is 90cm

Example with three blinds:
274cm – 2cm – 2cm = 270cm ÷ 3 = Finished width of each blind is 90cm

Step 3 – Measure the drop

Measure the drop from the top of the recess to the window sill on both the left and the right side. Make a note of the smallest measurement and use it for both blinds, so they hang evenly. Add at least 10cm so the fabric always has a roll at the top. This gives the blind weight and stability and makes it easier to roll up and down.

Example:
140cm + 10cm = Finished blind height 150cm

Step 4 – Choose the cord placement

We recommend placing the cord pull on the outer side of each blind (left blind: cord on the left, right blind: cord on the right). This keeps the cords from hanging together in the middle and makes each blind easy to reach.

Step 5 – Ordering the roller blinds

Enter the final width and height measurements taken from step 2 and 3, and choose the cord placement, when ordering the roller blind on our website.

Please double-check all measurements before placing your order to ensure a perfect fit!
