Our step-by-step instructions make it easy to take accurate measurements and get the right fit.
For a beautiful framed look
Measure to the nearest 1⁄8 in. between inside surfaces of window frame; at the top, middle, and bottom. Record the narrowest width of the three.
Measure to the nearest 1⁄8 in. from inside surface at top of window to top of sill; at the left, middle, and right. Record the tallest height of the three.
Measure exact depth of window casing making note of any obstacles i.e. handles, tracks or cranks that could interfere with the blind or shade function. Use the shortest depth.
For increased light control and privacy
Measure to the nearest 1⁄8 in. between outermost points where shade is to be placed. Measurement should overlap each side of window frame by at least 1 1⁄2 in.
Measure to the nearest 1⁄8 in. from where top of shade will be located to top of sill, or measure to point of shade reach if no sill.
