How to Measure for Window Blinds

Vertical Blinds - Outside Mount

Outside Mount

Outside Mount Example

The mounting brackets sit outside and above the window. With this mount, the shades or blinds cover the window frame as well as the window. The outside mount is often chosen to help ensure there is no light gap at either side of the window.

Measuring for the Outside Mount

Inside Mount Example
  1. Measure the width across the window where you want the blind to cover. We recommend you add 4 inches on each side of the window opening to prevent a light gap. Record the measurement.
  2. Measure the opening’s height. Add enough to the height so that the mounting brackets will clear any window frame or trim. The height you provide will include the height of the headrail. If you plan to have your window treatment hang down to the floor, allow at least 1/2" clearance on the bottom for proper operation.
  3. Record your measurement as WIDTH × HEIGHT.
  4. The factory will not take any deductions from or adjustments to your measurements. Deductions are only taken for inside mounts. Your vertical blinds will arrive with the exact measurements you provide.
  5. Double check your measurements! There are no refunds or returns based on incorrectly measured, recorded or conveyed measurements.
