Measuring for your new blinds is really straightforward, just see the guide below. We recommend that you use a steel tape measure for accuracy. Decide the fitting position of the blind, within the recess [recess] or outside the recess [exact].
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 longest height measurement.
[Outside the window opening, overlapping the window recess] 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.
