How to measure for double roller blinds: Inside recess

To fit your double roller blind inside the window recess, follow these instructions. Don’t worry about making any deductions. When you choose recess as your installation method, we make the necessary deductions to ensure your blind fits neatly, without the blind or fittings scraping against the wall, and the slats and bottom rail will hang beautifully without dragging on the window sill.

Step 1

Measure the Width

Measure the width of your window recess in three places, top middle and bottom. Use the smallest measurement as your width.

Step 2

Measure the Drop

Measure the drop of your window recess in three places, top middle and bottom. Use the smallest measurement as your drop.

Step 3

Enter your Measurements

Go to your chosen product, enter your width and drop measurements, select Inside Recess as your sizing option.

Deductions

We will make a small deduction to the width of your blind when you select Inside Recess to accommodate the brackets.

Important Notes

Factor in Obstructions

If you have obstructions within your recess e.g. tiles, measure between these two points and use this as your width measurement.

 

Check your Recess Depth

Ensure you have at least 10.5cm clearance between the front of your window recess and the edge of any obstruction.

How to measure for double roller blinds: Exact size

To fit your double roller blind outside the window recess, follow these instructions. Your blind will be made exactly to the size you give us. As per the instructions, you’ll add extra width and drop to the window space so your double roller blinds overlap the recessed space neatly.

Step 1

Measure the Width

Decide how much overlap you want your blind to have on each side of your window recess. Measure this width.

Step 2

Measure the Drop

Measure the drop from where you want the top of the blind to start, and the bottom to finish. This is your drop measurement.

Step 3

Enter your Measurements

Go to your chosen product, enter your width and drop measurements, select Exact Size as your sizing option.

Note

We will not make any deductions to your measurements when you select the Exact size option.

Important Notes

Left and Right Overlap

We recommend your blind overlaps the window recess by at least 5cm on each side (10cm overall). You will eliminate more light the more the blind overlaps the recess.

 

Top Overlap

We recommend your blind overlaps the top of the window recess by at least 7cm.

 

Bottom Overlap

If your window sill protrudes more than 5cm, you should stop your blind at this point. Be aware of obstructions such as radiators when measuring your drop.

Recommened Split Point

If you have a vertical window mullion or door frame, we'd suggest using this as your split point. Alternatively use the centre of the window you’re covering.

 

Blind Gap

There will be a small gap between the blinds to accommodate the brackets. The gap will be determined by how close you install the central brackets.

If you have any obstructions within your recess such as tiles, measure between this and your split point mark, use this as your width measurement.

 

Bottom Overlap

Be aware of obstructions such as radiators when measuring your drop. If your window sill protrudes more than 5cm, you should stop your blind at this point.

By combining these two layers, double roller blinds offer flexibility, enabling homeowners to adjust their window coverings to suit their specific lighting and privacy preferences.
