Accurate numbers are the foundation of any window covering project because they determine how well the product will fit and operate. When the measurements are correct, you avoid gaps, improve privacy, and get a cleaner finished look. This guide explains how to measure a window for blinds and shutters in a clear and practical way. With the right steps, you can plan your budget, compare options, and move forward with confidence.
Why Accurate Measurements Matter
Correct measurements are the key to a custom fit. If the numbers are off, your blinds or shutters may leave gaps, not close well, or reduce privacy.
Different windows need different approaches:
- Shallow windows often need coverings that mount outside the frame.
- Casement windows are deeper and allow for inside mounts.
- Egress windows are even deeper, offering more options.
Pro Tip: Always check window depth before you choose a style. It can change what product works best.

How to Measure Inside the Window Frame
Inside mounts sit within the frame for a clean look. To measure:
- Measure width at the top, middle, and bottom.
- Measure height on the left, center, and right sides.
- Record the smallest numbers for each.
This shows if the frame is uneven. Using the smallest numbers ensures a snug fit.
Key Takeaway: Always use the smallest measurement for inside mounts.
How to Measure Outside the Window Frame
Outside mounts cover more space and can make windows look bigger. They are also a good option if the window frame is not even.
- Measure the width and height of the area you want to cover.
- Add a few inches to block more light and improve privacy.
Outside mounts are ideal for shallow windows or if you want a bold frame look.
Setting a Budget With Measurements
With accurate numbers, you can get fair quotes and plan your spending. Measuring helps you:
- Compare blinds and shutters by size and price
- Plan room by room or for the whole house
- Choose products that meet your needs without guesswork
Pro Tip: Start with a simple range based on your window sizes. This keeps your project on track.
