How do I measure up for my blind?

Inside the recess

Use a steel tape, never a cloth dressmakers tape. Measure both sides for the depth, giving us the lesser of the two measurements, and measure the top and the bottom (window recesses are not always uniform) again, state the lesser dimension. It is easiest if you state the actual recess size and do not deduct anything.
However, if you prefer, you can make deductions and state that your order is actual blind size. Watch out for projections into the space the blind needs, such as tiling features, dado rails, window handles etc.

Outside the recess

Use a steel tape, never a cloth dressmakers tape. Measure the window and decide by how much you wish the blind to overlap at the sides, top and bottom. State the size and state that it is actual blind size outside recess fitting. You might find the window ledge obstructs the smooth operation of the blind. Either use a batten to bring the blind away from the wall surface so it misses the ledge, or stop the blinds drop at the ledge, if visually this is going to look OK.

Fitting

Full fitting instructions, screws and brackets are provided. You will need some standard DIY kit, such as screwdriver, plus drill and rawlplugs if you are drilling into masonry.
