Your window blinds are specifically made to your required measurements to suit your individual installation. To allow the blind to operate correctly you need to decide if it is a recess or exact situation.
Recess: Specify this if you require your blind to fit inside a window recess ,we will make the blind about 12mm smaller than the sizes you provide, this is to allow the blind to function correctly within in recess space.
Exact: This is where you require the blind to hang outside of the window recess, we will make the blind to the exact sizes you provide. As a general rule we recommend at least a 50mm overlap to all sides, this gives a good privacy coverage.
