This blind can be custom made to fit your window. Simply measure your window and order the next size up closest to your measurements. We will contact you by phone within one working day and your blind will be completed within 7 days after that. To measure up for blinds: Use a metal tape measure and make a note of your measurements to the nearest millimetre. For a blind inside a window recess: Make sure the recess your blind is going into is not obstructed in any way, so that the blind can hang freely when pulled down. Measure the total width and length from C to D (see image 5 above). As shown, do this in several places to allow for any slight variation for irregularity in your windows, then make a note of the narrowest measurement. For a blind outside a window recess: Decide how far you want the fabric to overlap at each side. Measure the installation height (see image 5). This will be from the height at which you intend to fit the headrail to the floor. Size restrictions: Minimum width 41cm. 0% APR Representative: If you buy this product in our shops, it's eligible for Interest Free Credit , which is available when you spend £1000 or more on selected home products.
