How to Measure for Cellular Shades
Get step-by-step guidance on measuring your windows for Kurlax Cellular Shades—whether you choose an inside or outside mount, we make it simple.
Inside Mount: 3 Easy Steps to Measure
A precise measurement is the key to a perfect fit. Inside mount motorized cellular shades sit inside your window frame for a clean, built-in look.
Step 1: Measure Window Recess Depth
Recess depth: >= 1 1/2" (3.8 cm)
Measure the flat mounting area and use the smallest depth if measurements vary.
With Solar Panel: Recess depth >= 2 3/8" (6 cm).
If the recess depth is less than 2 3/8" (6.07 cm), the headrail will extend beyond the recess.
Watch for Obstructions
Common obstructions inside the window recess may include:
- Window handles
- Latches or locks
- Winder mechanisms or cranks
Measure with Obstacles
Recess Depth: Front edge → back of recess.
Obstruction Depth: Back of recess → front of obstruction.
Clear Depth: Recess Depth − Obstruction Depth
- Without Solar Panel: > 1 1/2" (3.8 cm)
- With Solar Panel: > 2 3/8" (6 cm).
Step 2: Measure Window Width
Measure the Top, Middle, and Bottom.
Use the smallest measurement.
No deductions needed—we’ll adjust the width during production.
Step 3: Measure Window Height
Measure the Left, Middle, and Right.
Use the smallest measurement.
No deductions needed
Outside Mount: 3 Simple Steps
An outside mount fully covers the window and can block more light. This is ideal if you want maximum privacy or light control.
Step 1: Measure the Space Above the Window
Measure the distance from the top of the window frame to the ceiling.
Minimum height: 1" (2.5 cm)
If there is less than 1" of space, consider ceiling mounting instead.
Window Frame Projection
If your window frame protrudes from the wall and you plan to mount the shade to the wall, Extension Brackets may be required. Please include the projection depth of the window frame in your order notes so we can provide the appropriate brackets.
Step 2: Measure Width
Measure the window opening at 3 points: top, middle, and bottom. Use the widest measurement, then add 2–3 inches (5–7.5 cm) for the shade width.
Step 3: Measure Height
Measure the window opening at 3 points: left, middle, and right. Use the tallest measurement, then add 2–3 inches (5–7.5 cm) for the shade height.
Avoid These Common Measuring Mistakes
- Fabric tape: Use a standard steel measuring tape instead of a fabric one for accurate results.
- Glass-only measurement: Measure the full window recess, not just the glass area.
- Self deductions: Don’t make your own size deductions — we’ll adjust during production.
- Missed obstructions: Always check for handles, locks, or trim before taking final measurements.
- Angled measurements: Always measure straight along the window recess, not at an angle.
- Bent tape: Keep the measuring tape flat and straight for precise readings.
