Fitting Roman Blinds Outside the Reveal.
Step One. Decide on your preferred blind position. The top of the blind usually looks best at 10cm above the recess. For the hem position, blinds usually fall 5-15cm below the sill (or to the sill if the sill projects).
Measure the length between the top of the blind and the hem position. This is the finished length (measure in several places to find the length that best suits).
Step Two. Measure the recess width. Now decide how much the blind is to overhang beyond the recess either side and add this to your recess width (usually at least 5cm to each side, check for obstructions). This gives your finished width.
Step Three. Decide if you would like the Chain on the left or right or the blind.
Fitting Roman Blinds Inside the Recess.
Step One. Measure the length from the top of the recess to the sill in several places as your window may not be square, and choose the length that best suits. This is the finished length of your blind.
Step Two. Measure the width of the recess at its narrowest point. Subtract 1cm from the reveal width; allowing for a 5mm clearance to each side. This gives your finished width.
Note: Complete blackout will not be achieved.
Step Three. Decide if you would like the chain to the left or right of the blind.
Tip: Ensure that the blind is far enough away from the window handles to prevent obstruction. You may need to fix the blind to the top of the recess.
