How to Measure for Window Blinds

Horizontal Blinds - Outside Mount

Outside Mount

Outside Mount Example

The mounting brackets sit outside or on top of the window frame. With this mount, the shades or blinds cover the window frame as well as the window. The outside mount is often chosen to hide an unattractive window or create the illusion of a larger window.

Measuring for the Outside Mount

Inside Mount Example
  1. Measure the width across the window where you want the blind to cover. You can typically add 4 to 6 inches (2 to 3 inches on each side) to the actual width of the window to ensure that the sunlight doesn’t peak through the ends and to improve insulation. Record the measurement. (Caution: if you add an excessive amount to each side, creating a shade much longer than the window’s width, your shade or blind may appear overly large when the shade is raised and the window frame beneath can be seen.)
  2. Measure the height of the window where you want the blind to cover. Record the tallest measurement.
  3. Record your measurement as WIDTH × HEIGHT.
  4. The factory will not take any deductions from your measurements. Deductions are only taken for inside mounts. Your blinds/shades will arrive with the exact measurements you provide.
  5. Blinds stack at the top. If you do not want the blinds to obstruct your view when fully stacked, allow enough room above the window for the stacking. Stacking information is found on each product page.
  6. Double check your measurements! There are no refunds or returns based on incorrectly measured, recorded or conveyed measurements.
