Measuring Instructions for Cordless Blackout Top Down Bottom Up Single Cellular Shades

Let's make sure you have what you need!  

1. A metal tape measure
2. Pen and paper to record all measurements
3. Check if you have sufficient depth: Measure inside the window opening from the front to the back of the opening where the blind would mount. The depth must be at least 1 3/8”. To have a flush mount (fully recessed) the depth must be at least 2 1/8”. If your depth is not sufficient please see our outside mount instructions

How to Measure

1. Let's start with the Width:
   • Inside of the window opening/frame measure from left to right at the top of the opening, the middle of the opening, and then the bottom of the opening. Write down all 3 measurements and circle the narrowest. If rounding is necessary, round down to the nearest 1/8”.  That is your ordering width.
2. Now, let's do the Height:
   • Inside of the window opening/frame measure from the top of the opening to the bottom of the opening/sill on the left-hand side, the middle, and on the right-hand side. Write down all 3 measurements and circle the tallest. That is your ordering height.

Note: The factory will make the necessary deduction of approximately 3/8" to your Width to account for movement in the window opening and to ensure that the valance will fit. No deductions will be made to your Height.

Before you start measuring, decide whether you will mount on the window trim or above the window trim. Perhaps you are measuring for a door mount? We have instructions for that too! Please note that you must have 1" of flat space to mount the bracket on the trim. If you do not have sufficient space, you will need to mount to the side of your trim or above your trim.
