Window shades are a great way to add style and privacy to any room. But before you buy them, you need to know the right way to measure your windows. A perfect fit makes your home look better and helps your shades work the right way. In this guide, you’ll learn how to measure window shades easily, even if you’re doing it for the first time.
Types of Window Shades
Before you start measuring, you should know what kind of window shades you want. Each type may need a slightly different measurement.
Here are some popular types:
- Roller shades – These are smooth and simple. They roll up and down.
- Roman shades – These fold neatly when raised.
- Cellular shades – Also called honeycomb shades, they help with insulation.
- Blackout shades – These block out most or all light. Great for bedrooms.
- Zebra shades – These give you both light control and privacy with their striped design.
Different shades may hang or sit in your window differently. That’s why the type matters when measuring.
Inside Mount vs. Outside Mount
Window shades can be mounted two ways:
- Inside mount: The shades fit inside the window frame. This gives a clean, built-in look.
- Outside mount: The shades sit outside the window frame. This works better if your window frame is too shallow or uneven.
Knowing how you want to mount your shades will change how you measure your windows.
Tools You’ll Need
Here’s what you’ll need to measure for window shades:
- A metal measuring tape (not a cloth one)
- A pencil and notepad
- A step stool or ladder (for tall windows)
Measuring your windows the right way means your shades will fit just right and look amazing.
How to Measure Inside Mount Window Shades
Follow these steps to measure inside your window frame:
- Measure the width at the top, middle, and bottom of your window.
- Use the smallest number.
- Measure the height on the left, center, and right side.
- Use the largest number.
- Check the depth of the window frame to make sure it can hold the shade.
Write down your numbers and don’t round them. Even small changes matter. Accurate window measurement helps you avoid gaps that let in light or make shades look off.
How to Measure Outside Mount Window Shades
Here’s how to measure for shades that go outside the window frame:
- Measure the width of the window and add 2–3 inches on each side.
- This gives you better coverage and privacy.
- Measure the height from the top of where you’ll mount the shade to where you want it to stop.
- Add extra inches if you want full coverage.
This method is great if your window frame is shallow or has obstructions like handles or cranks.
Common Mistakes to Avoid
Many people make simple mistakes when measuring window shades. Avoid these:
- Using a fabric tape – Use a metal measuring tape for accuracy.
- Rounding measurements – Always use exact numbers.
- Measuring only once – Double-check to be sure.
- Forgetting obstacles – Watch out for locks, cranks, or trim.
When you take your time and measure carefully, you avoid buying the wrong size.
When to Call a Professional
You may want help if:
- You have arched, bay, or oddly shaped windows
- You want motorized shades
- You’re buying layered window treatments
A professional can make sure your custom window treatments are done right the first time.
Final Tips Before Ordering
Before you place your order:
- Double-check all measurements.
- Know your mounting type (inside or outside).
- Choose a shade that fits your needs (like blackout shades for bedrooms).
- Make sure your window frame is deep enough for an inside mount.
When in doubt, reach out to the store for help. Many companies offer free measuring services.
