Measuring Instructions for Deluxe Blackout Fabric Roller Shades

Let's make sure an inside mount will work for your window!  Using a metal tape measure, first check if you have sufficient depth:

• Measure inside the window opening from the back of the window to the front of the opening where the shade would mount. To mount the brackets, the depth at the top of the window must be at least 2 1/4" for shades without a cassette valance and 2 5/8" for shades with a cassette valance. To have a flush mount (meaning the shade is fully recessed in the window opening) the depth must be at least 3" without a cassette valance and 3 1/2" for shades with a cassette valance. If your depth is not sufficient for mounting the brackets, please see our outside mount instructions or consider a different product.

How to Measure:

Let's start with the Width:

• Measure inside of the window opening/frame from left to right at the top of the opening to the nearest 1/8". If rounding is necessary, round down to the nearest 1/8".  That is your ordering width.

Now, let's do the Height:

• Measure the inside of the window opening/frame from the top of the opening to the bottom of the opening/sill to the nearest 1/8" in three places: 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: Always provide us with the actual measurement of the window opening. We will make the necessary deduction of approximately 1/8" to the width of the top of the shade to accommodate the installation brackets. 

The fabric portion of the shade will be approximately 1" – 1 1/2" narrower than the ordered width (up to 3/4" gap on each side between the window opening and the edge of the fabric). When maximum light blocking is needed, consider an outside mount or an alternate product. 

No deductions will be made to the ordered height. 

Before you start measuring, decide where above your window opening you want to mount your shade. You will need at least 1 1/2" of flat vertical space above the window to mount the brackets for shades without a cassette valance, or at least 2" for shades with a cassette valance. Follow the directions below for where you'd like to install your shade.

If you do not have sufficient vertical space for mounting the brackets, please see our inside mount instructions or consider a different product.

Your ordered width will be the "tip to tip" measurement, which is the widest part of the top of the shade including the brackets and cassette valance (if applicable). The fabric portion of the shade will be approximately 1" – 1 1/2" narrower than the ordered width (up to 3/4" on each side. If you wish to have the fabric cover a specific width, we recommend ordering slightly wider – just ensure that you have enough horizontal space to mount the shade.
