How to Measure
Let’s make sure an inside mount will work for your cellular shades!
Using a metal tape measure, first check your inside mounting depth. Depth is measured from the window glass/back of the opening to the front edge where the brackets will sit.
Minimum inside depth (bracket mounting):
• 3/8" Single Cell: at least 1"
• 5/8" Single Cell: at least 1 3/16"
Depth required for a flush (fully recessed) mount:
• 3/8" Single Cell: 1 11/16"
• 5/8" Single Cell: 2 1/8"
If your depth is not sufficient, please use our outside mount instructions. If space is limited, extension brackets can be purchased separately for installation.
How to Measure:
Let’s start with the Width:
- Measure the inside of the window opening from left to right at the top to the nearest 1/8". If rounding is necessary, round down to the nearest 1/8". That is your ordering width.
Now, let’s do the Height:
- Measure from the top inside of the opening to the bottom sill to the nearest 1/8" in three places: left, middle, and right. Write down all 3 and circle the tallest. That is your ordering height.
Note: Always provide the actual window opening measurements. For inside mounts, we may make a small deduction to help ensure smooth operation and bracket clearance.
Before you start, decide where you want to mount your cellular shades (above the opening, above the trim, on the trim, or on a door).
You’ll need a flat surface for the brackets:
Minimum wall surface (Outside Mount):
• 3/8" Single Cell: 1 3/4"
• 5/8" Single Cell: 1 7/16"
If space is limited, extension brackets can be purchased separately for installation.
Your ordered width is typically the widest part of the headrail/cassette (tip-to-tip). For the best light control and appearance, we recommend ordering wider than the glass/opening.
Above the Window (No Trim) ›
Width:
Decide how much coverage you want around the opening. We recommend extending the shade 2"–4" on each side for better light control.
Measure left to right including your desired extra space — that is your ordering width.
Height:
Measure from where the top of the shade will be mounted down to where you want the bottom of the shade to reach. If you have a protruding sill, measure to the top of the sill (or to your preferred stopping point). That is your ordering height.
Above the Trim ›
Width:
We recommend extending the shade 2"–3" past each side of the window opening for a cleaner look and improved light control.
Measure left to right including the extra space — that is your ordering width.
Height:
Measure from where the top will be mounted down to your desired bottom point. If you prefer, you can measure to the bottom of the trim; for protruding sills, measure to the top of the sill. That is your ordering height.
Note: If your trim is thick and you need extra clearance, use shims or consider extension brackets.
On The Trim ›
Width:
We don't normally recommend mounting cellular shades directly on the trim unless your window configuration doesn't allow for other placements. Your ordering width must fit within your trim width.
Measure outer edge to outer edge of the trim at the top — that is your ordering width.
Height:
Measure from the top of the trim to the bottom of the trim (or to the top of the sill if you have a protruding sill). That is your ordering height.
Door Mount ›
Width:
Measure left to right from the outside edge of the glass trim to the other outside edge. If space allows, order the shade 2"–4" wider for better light control.
Height:
Measure from where you want the top mounted down to where you want the bottom of the shade to stop. That is your ordering height.
