Measuring Guidelines



Please keep in mind we cannot accept returns based upon incorrect measurements. We recommend hiring a window treatment installer to help measure and install your Designs By Spirit custom printed window blinds. If you need assistance, we can help you find a certified installer in your area.


If you choose to submit your own window measurements, please follow our measuring guidelines using a steel measuring tape. Do Not make deductions, we will make the necessary deductions when manufacturing your Designs By Spirit custom printed window blinds.

If you are measuring for more than one window, please record your measurements beginning with the furthest left window facing your windows. Please double-check your measurements before submitting and be sure not to transpose your width/height specifications. If you need assistance, please call 208.304.3839 (8am to 6pm, Monday thru Friday, PST).

​Inside Mount

Width: Start your measurements at the depth where your brackets will be installed and measure your window’s width at the top, middle, and bottom of opening edge to edge. Record the narrowest of the 3 width measurements to the nearest 1/8".


Height: Measure your inside mount window height edge to edge in 3 places: left, middle and right. Record the tallest of the 3 height measurements to the nearest 1/8".

Outside Mount

An outside mount can be adjusted for irregular sizes and is a good choice if your window opening has no recess or if the window is out of square. For outside mount measurements, determine how wide you want the blind, allowing for the mounting brackets and measure to the nearest 1/8 inch.
