How To Measure Fabric Blinds

Everything you need to correctly measure for fabric blinds

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 fabric blinds will hang entirely within the window frame

Outside mount fabric blinds will hang outside your window opening, overlapping the edges

We recommend outside mount for out-of-square windows, and for windows with minimal mounting depth or obstructions within the frame
Minimizes light gaps, giving you better light control and privacy

Note: Inside mount blinds 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 blinds 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 blind to overlap the window opening); we recommend 1 ½” on both sides
Record your measurement

Height

Determine where you want the top of your blind 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
