Please measure the inside width of your window frame across the top of the frame, and the inside height of the window frame. Measure your window frames twice to ensure that you get the same result each time and to ensure it is accurate.
Provide us exact measurements to the nearest millimetre and do not make any deductions to allow for brackets, as we will do this once the order is placed.
For blinds that are being installed on the outside of the window frame (external fit), take the measuements from where you want the brackets to be fixed. Please contact us if you are unsure.
