Expert Guide: How To Measure For Window Blinds
Use our simple step by step guides and videos to find out how to measure your standard windows, angled bay windows and boxed bay windows. Measuring yourself couldn’t be easier, takes just minutes and will save you money!
All our blinds are made with a 5mm manufacturing tolerance (width & drop), this tolerance is separate to the deduction made for a recess size product.
Standard Window
If you want your window blind to fit inside, or to hang outside the window recess use our simple step by step guides and videos below to find out how.
Recess Size
Inside Window Recess
This is the measurement you need to make if the blind needs to fit inside the window recess. Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement.
We will make any necessary deductions to ensure the blind fits neatly within the recess of the window.
For roller blinds we only require you to measure the top width of your recess and provide this when placing your order.
Please note that the actual fabric will be approximately 3-4cm narrower than the recess width depending on the blind ordered.
We don’t recommend roller blinds for bay windows, as the fabric is narrower than the full blind width (by around 3–4 cm). This creates gaps between blinds in a bay, reducing privacy and light control. For a better fit, consider alternative blind styles.
Our fabric experts recommend when ordering a blackout blind, you fit this outside the window recess using the ‘exact’ blind measurement thus ensuring as much external light as possible is blocked out.
The headrail is included in the drop of the blind therefore the louvres will be shorter than the drop.
Exact Size
Outside Window Recess
An exact size blind is also known as ‘pin width’ or ‘finished blind width’. This is the measurement you need to make if the blind needs to hang outside the recess overlapping the window. Decide how much you wish to overlap the recess at each side, we recommend at least 7.5cm at each side as well as the top and bottom so as to minimise as much external light as possible.
Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement. We will not make any deductions from the measurements provided.
Please note this width includes the mechanism of the blind and is not the width of the cloth.
The headrail is included in the drop of the blind therefore the louvres will be shorter than the drop.
Fench Doors
If you want your window blind to fit inside, or to hang outside the window recess use our simple step by step guides and videos below to find out how.
Recess Size
Inside Window Recess
This is the measurement you need to make if the blind needs to fit inside the recess where your door sits. Measure the width wall to wall, then the drop from the top of the recess to the floor. Repeat this in three different positions ensuring you provide us with the smallest measurement.
We will make any necessary deductions to ensure the blind fits neatly within the recess.
Top Tip: Remember to ensure you check for any incompatibilities between your door type and chosen blind (for example if your door opens inward).
