How To Measure for Inside-Mount Window Blinds
With or without draperies, window blinds offer light control, privacy, and beauty to any room. It's critical to measure accurately for inside-mount blinds. We'll tell you how.
Time Required: Varied
For an "inside mount blind" you must determine if there's enough room to install a blind and its heading in the window opening. If the edge of the window is flush with the wall, you'll need to use an "outside mount" blind.
Measure the width of the window opening in 3 places--at the top, in the middle, and along the bottom edge or sill. Use the measurement to within 1/8 inch. You'll use the narrowest of these three measurements for your inside-mount blind width.
Measure the height of the window opening in 3 different places--along the left side, in the middle, and along the right side. Use the measurement to within 1/8 inch. You'll use the longest of these measurements for your inside-mount blind length.
Always measure to the nearest 1/8 of an inch. Do not round the measurement up or down.
When writing the measurement, list the width first, then the height. The proper measurement would be "width X height."
If you are not sure about how to make accurate measurements, you'll want to pay to have someone from the blind company come to your home to measure.
If you provide your own measurements, you'll be responsible if the blinds do not fit. Blinds are custom items and must be perfect to look right.
