For Fitting inside the Window Reveal
1. Measure the length from the top of the reveal 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.
2. Measure the width of the reveal 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.
3. Choose a mechanism and to which side this will hang.
Ensure that the blind is far enough away from the window handles to prevent obstruction. You may need to fix the blind to the ceiling of the reveal.
