Blind Measurement Guidelines

Measuring your windows correctly is the first step to ensuring your custom blinds fit perfectly. With accurate measurements, your window treatments will look clean, elegant, and professionally installed.

Inside Recess or Outside Recess: Your First Decision.

Before you grab a tape measure, you need to choose your mounting style. Each offers distinct benefits and suits different windows and needs.

How to Measure

Before You Measure

Tip: If you’re unsure which mount to choose, measure for both options before making a decision.

Step1
Decide on Inside Recess or Outside Recess first
Step2
Use a metal tape measure (not cloth or soft tape)
Step3
Measure to the nearest 1/8 inch. Do not round up
Step4
Always write measurements as Width × Drop

Inside Recess (Recess Fitting)

Window Depth : Minimum 2.8" required.
Window Width : Measure the inside window width at the top, middle, and bottom. Use the smallest measurement.
Window Height: Measure the inside window height at the left, center, and right. Use the largest measurement.
Order Width = Window Width - 1/8"
Order Height ≥ Window Height (For Zebra Blinds: Order Height = Window Height)
