Before starting, decide whether you want your blinds in the recess or outside the window.
For a neat fit that blocks out the light choose to fit your blinds inside the recess. For windows that are not straight or have lots of obstructions choose to fit your blinds outside the recess. This way you will be sure of a perfect fit for your blind.
Blinds inside the recess – Recess measurement
Width – Measure the inside width of the window at the top middle and bottom. Use the narrowest width measurement.
Height – Measure the height of the window at the left, centre and right. Use the shortest height measurement to the nearest millimetre
Blinds outside the recess – Exact measurements
Width – To minimize light leakage it’s recommended that the blind overlaps the window recess by least 50mm each side.
Height – When measuring the height take into account the required space for the mounting bracket, a flat surface of a minimum 70mm is advisable.
Things to Remember
Always use a steel tape measure for accuracy
Measure in centimeters and round each measurement to the nearest 0.1cm.
Measure all windows, even those that appear to be the same width and height.
Remember to specify ‘Recess’ or ‘Exact’ size
Look out for any obstructions such as window handles, tiles, dado rails etc and take their position into account if necessary.
Measure twice to avoid a costly mistake.
