How to measure blinds
For windows with a depth of 2 inches 1/2 or more, BLINDS ON SALE EXPRESS recommends opting for an inside installation.
Also, no matter the size of your window, its frame must be a minimum of 2 inches 1/2 deep. Otherwise, the housings of your blinds will not be properly recessed into your window.
To properly determine the dimensions of your window, you need to measure the width at the top of the inner window frame as accurately as possible (see illustration).
Don’t subtract any inches! We automatically deduct ⅛” (for each side) from the measurement provided in order to leave space for the mechanism.
The blind fabric will be 1 ¼” less than the measured width in order to keep a small space on each side.
If your patio door is double, you need to measure the total width of your patio doors.
Then select a blind for each panel (one chain on the right, one chain on the left).
For patio doors with 3 or 4 panels, please contact us by email, we will be able to assist you with your order.
Don’t subtract any inches, we’ll do it for you!
