How To Measure Vertical Cellular Shades

Everything you need to correctly measure for vertical cellular shades

Getting Started

Tips before you get started:

Use a steel tape measure for the most accurate measurements
If you’re considering an Inside Mount, make sure your window has enough depth to accommodate it
Always measure width (left to right) first and height (top to bottom) second
Record all measurements to the closest 1/8”, making sure to clearly identify which is your height and which is your width—it is very common to get them mixed up

Tools you will need:

Inside mount vertical cellular shades will hang entirely within the window frame

Outside mount vertical cellular shades will hang outside your window opening, overlapping the edges

We recommend outside mount for patio doors and sliding doors
Minimizes light gaps, giving you better light control and privacy
For an outside mount, be sure to allow for the height of the vertical shade's headrail in your measurement

Note: Inside mount shades will have a small deduction automatically applied by the manufacturer, to ensure proper fit.

Width

Measure at the depth within the frame where you’ll install your brackets
Measure width at the top, center and bottom of your window opening, from edge to edge
Record the smallest measurement of the three to the closest 1/8”

Height

Note: Outside mount shades will have no deductions taken at the factory. They will be made according to your exact measurements.

Width

Measure the area you want to cover (how far you want the shade to overlap the window opening); we recommend 1 ½” on both sides
Record your measurement

Height

Determine where you want the top of your shade to be and mark the spot
Measure the height from the spot you marked to the top of the window sill. If there is no sill, measure below the window opening to your desired length
