● Measurement must be accurate.
● Always measure the width first and write it down before measuring the drop.
● Measure the drop and write it down.
● Now re-check your width and drop measurements.
The blind hangs outside the window opening and covers an area larger than the window itself.
Measure the width you require to cover. Add 50mm past either side of the window opening for greater privacy.
Measure the drop you require to cover. Add 50mm past top and bottom for greater privacy - or to the top of the sill or to the floor. Measure three-drop measurements, left side, the middle and the right side and only, write down the smallest measurement of the three. This is to ensure that the window is not out of square.
Only supply exact measurements in millimeters. The factory will make allowances to ensure a proper fit.
The blind hangs inside the window frame and covers the window opening exactly.
Measure the exact width and again measure at three points on the window top, middle and bottom portion to ensure that the window is not out of square. But only write down the smallest measurement.
Measure the exact drop measurements at three points on the window, left side, middle and right side. But only write down the smallest measurement.
This is a guide on how to measure for a roller blind with obstructions inside the window recess; these could be either tiles or a dado rail.
Take the measurement 'Width' at the narrowest point inside the obstructions using a metal tape measure.
Because the fabric of a roller blind is 34mm smaller than the overall width of the blind (this is because the overall width of the blind includes the end sets and the brackets). Add 20mm onto measurement 'Width' so that when the 34mm allowance is made for the end sets and the brackets, the fabric will be approx 14mm narrower than measurement 'A', allowing the fabric to freely clear the obstruction.

Allowances and Deductions for Window Blinds.
Inside Recess Size :
When manufacturing the blind we deduct a standard 10mm on the width of the blind so that the blind will operate freely (except for roller blinds).
The deduction we make to the height of the blind is dependant on the type of blind you have chosen. The deduction for vertical blinds will be 12mm on the drop in order for the blind to operate perfectly.
For venetian blinds however the deduction on the height will be between 20-40mm to allow for movement and free slat operation
Exact Blind Size :
When choosing this option your blind will be manufactured to the exact dimensions you have ordered. Check that when measuring this option you make any allowances for things that could impede the operation of your blind when fitted such as door/window handles etc.
Also note that there is a standard tolerance of up to 5mm during the manufacturing process
