3. Clearly indicate which measurment is the width and which is the height.

4. Do NOT take deductions for an inside mount. The factory takes those allowances. You need to provide your exact window size.

5. You need to provide the exact overall blind size needed for an outside mount.

Inside or Outside Mount :

Decide if you want to mount the blind inside the window or outside on the wall or moulding. For an inside mount, the window opening must have enough unobstructed depth to allow mounting. Important: For a flush inside mount check that you have enough depth and make sure you request the valances be made the same width as blind since they are normally made an inch or two wider. We recommend inside mounts when possible as it provides a cleaner look. An outside mount can make a window appear larger or hide a window. When using a inside mount, we make a size deduction allowing for operating clearance for the blind. We will deduct up to 1/4" from each side ( vertical blinds require a height deduction of 1/4"). The deduction is made to allow the blind not to rub or scratch your window frame. With an outside mount, your blind will be made at the exact size you specify. You should add to the opening measurement for overlap and mounting brackets. Read product specific measuring instructions before ordering.
