If you have an awkwardly-shaped window then measuring it up to fit a blind can pose a real problem. Recess and bay windows can be particularly problematic, and that’s why expert fitters at Wooden Blinds Direct have designed some useful guides for you to follow. You’ll be able use them to measure your own windows, without the need for hiring a professional.
When fitting a blind to the average recess window, there are two main methods to follow. If fitting the blind in the recess of the window and not the outside, then you’ll need to use a recess fit. To do this, three separate measurements need to be taken of the height of the recess, and three for the width, as shown in this diagram:
You then need to take off around 1.5cm from the width of the smallest measurement, to account for clearance. Don’t take anything off the height unless you’re measuring for a vertical blind, in which case we recommend deducting around 2cm.
When fitting a blind for a recess window you can also measure an outer fit of the recess. To do this you simply need to take measurements of the areas to be covered by the blinds, as shown in the following diagram.
If you’re fitting vertical blinds then you should allow for clearance by taking off about 2cm.
Bay windows can prove an especially tricky shape to measure, because you can sometimes end up with blinds that don’t fit together well and overlap. You’ll need to decide which bay window blind style you’d like to fit before measuring, because there are three to choose from, as described below.
Type A: Full front
Full front blinds tend to be the most popular choice. This method should be used when you need maximum coverage of a front window, to prevent people from looking into your house or simply to keep out sunlight. Small gaps between the front and side blinds are usually obscured by the window frame.
You’ll first need to measure the recess where the blind is to be fitted, as the recess size may vary from top to bottom, by following the recess fit guide above – and taking off around 1.5cm from the width and height for clearance.
As each side recess might be a little different, you should measure each individually, using the recess fit guide above. You’ll then need to deduct the depth of the front blind from the width of each side, as well as taking around 3cm off for clearance and to prevent the blinds from overlapping.
Type B: full sides
This method should be used when you want maximum coverage of your side windows. Again, follow the recess fit guide when measuring for the front blind, and deduct around 1.5cm from the width and height for clearance – as well as taking off twice the depth of the blinds that are being used for the side windows.
Again, side recesses should be measured individually and 1.5cm deducted for clearance and to prevent overlapping.
Type C: symmetrical corners
This method should be used when you do not want your blinds to overlap in the corners, and give you a more symmetrical look. As before, the window frame will usually obscure any small gaps between the front and side blinds.
Follow the recess fit guide and measure the recess, deducting around 1.5cm for clearance from the width and height, as well as twice the depth of the blinds you’re using for the side windows.
Measure each side recess individually using the recess fit guide, and deduct the depth of each from each side of the side blinds – as well as a further 1.5 cm for clearance, to ensure the blinds don’t overlap.
