Measure the width
To fit your blind inside the recess:
If ordering a blind to fit inside the recess, measure the width of the recess in 3 different positions and supply the smallest width and we will make the necessary allowances for you by deducting 0.5cm.
Please note any protrusions (such as tiles and wooden rails) and take the smallest width and drop measurement.
To fit your blind outside the recess:
Simply measure where you would like the blind to sit and supply that measurement. No allowance will be made and the dimensions supplied will include head rail and brackets.
We recommend that a blind does not extend more than 10cm either side of the window and approximately 10cm above and below. If the window ledge protrudes out we suggest that the blind sits just above or on the sill once closed.
