Measuring for Woven Wood Blinds:
Please note: You should always use a metal tape measure
RECESS
GIve us the tight measurement and we will make the allowances

Width = A - B
Measure accross the top, middle and bottom and give us the narrowest width.
If you have tiles halfway down measure between the tiles.
Drop = C - D
OUTSIDE RECESS
This is the actual size you want the blind to be made

Width = E - F
Overlap the recess by approximately 25mm to 50mm either side to suite your requirements IE: allowing for any obstructions.
Drop = G - H
Measure 75mm approximately above the recess to the point where you want the Blind to finish.
