Window Blinds Measuring Guide

All our blinds can be fitted into the face of your window frame, wall or into the top of the lintel. This gives you complete control over the fitting of your new blind.

There are generally two fitting options for your new window blind, recess or exact. The exceptions to this are our ranges of blinds for Velux and Fakro windows (these are made to fit the window size exactly, we simply require the window code) and our range of blinds for tilt and turn windows where all you need to do is measure the visible glass size.

Recess: This is the measurement you need to take if you want your blind to fit inside the window recess. Measure the full width and height of the recess [the size of the hole if you like] and we will make the appropriate deductions to ensure a perfect fit.

Exact: This is the measurement you need to take if you want your blind to hang outside the recess overlapping the window. In this case we will make the blind to your specified size with no deductions.

Width: Measure the inside width of the window recess at the top, middle and bottom. Use the narrowest width measurement.

Drop: Measure the height of the window at the left, centre and right. Use the shortest height measurement

Standard sizes specially designed to enable you to easily trim the width and adjust the drop if needed. Simply measure your window recess and order the next size up you can then trim the blind to your required size.

On our made to measure service simply enter your measurements, specify recess fitting, and we will make the appropriate deductions for you to ensure a perfect fit.

Width: Measure the exact width of the area you would like the blind to overlap. To minimize light leakage we recommend that the blind overlaps the window recess by at least 50mm each side. In the case of roller blinds, the fabric will be approximately 35mm less than the overall measurement so don't forget to add this on if you are looking to achieve a specific fabric coverage.

Drop: When measuring the height take into account the required space for the mounting brackets, a flat surface of a minimum 50mm is required. Measure from the top of where you would like the blind to start to the bottom of where you like the blind to stop. The overlap at the bottom of the blind is a matter of personal choice but please take into account obstacles such as radiators.

Standard sizes specially designed to enable you to easily trim the width and adjust the drop if needed. Simply measure where you would like the blind to fit and order the next size up, you can then trim the blind to your required size. If you can be flexible on the amount of overlap in many cases you will not need to trim the blind.

On our made to measure service simply enter your measurements, specify exact fitting, and we will supply the blind at that size with no deductions.
