How to Measure Light Filtering Single Cellular Shades

Inside Mount

  • Mounted within the window frame
  • Provides a clean, built-in look
  • Great way to leave attractive woodwork exposed
  • Minimum depth required for inside mount: 1 1/4"
  • Depth required for inside flush mount: 2"
  • Minimum flat space required for outside mount: 1"
  • If window frame isn't deep enough, please select outside mount

Outside Mount

  • Great option when there is not enough depth for an inside mount
  • Mounted to the wall, ceiling or molding surface surrounding the window
  • Often used to make the window appear larger or to hide a less attractive window or door
  • No minimum depth requirement
  • Minimum flat surface (on wall, ceiling, or frame) required for secure mount: 3/4" for standard and top down/bottom up; 1/2" for continuous loop, deluxe cordless and cordless Top Down/Bottom Up. Be sure to take into account the flat mounting surface area when measuring the area you want to cover with your shade. The factory will make the fabric width of your shade to the width ordered. The headrail width will be 1/4" wider than the width ordered. The factory will make the height of your shade to the height ordered (including the headrail at the top of your shade).

Measuring for Inside Mount

STEP 1: Measure the inside width at 3 locations - the top, middle and bottom. Record the smallest of the 3 measurements. This is your ordering width. We will make the necessary deductions (approx. 3/8" to 1/2").

STEP 2: Measure the height at 3 locations - the left side, middle and right side. Record the largest of the 3 measurements. This is your ordering height.

Measuring for Outside Mount

STEP 1: Measure the width of the area you wish to cover. If space allows we recommend adding 2-3" (1-1 1/2" each side) to this measurement to help eliminate light seepage. This is your ordering width. The factory will make the fabric width of your shade to the width ordered. The headrail width will be 1/4" wider than the width ordered.

STEP 2: Measure the height of the area you wish to cover. This is your ordering height. Be sure to take into account the flat mounting surface (listed above) needed when measuring the area you want to cover with your shade. The factory will make the height of your shade to the height ordered. Generally 3" - 4" added to the height of your opening (including molding or framework you wish to cover) will allow you room to mount above the window frame.
