How to Measure a Window for Blinds


Choosing the right blinds for your windows can greatly enhance the aesthetics and functionality of any room. However, to ensure a perfect fit, it is crucial to measure your windows accurately. This article will guide you through the process of measuring your windows for blinds in a few easy steps.


1. Why is it important to measure windows for blinds?

Measuring your windows accurately ensures that the blinds fit perfectly, allowing for proper light control and privacy. Ill-fitting blinds may not only look unattractive but can also affect their functionality.

2. What tools do I need to measure my windows?

Measuring tape, a pencil, and a notepad are the basic tools you’ll need. Additionally, having a step ladder or stool can be helpful if your windows are located higher up.

3. How do I measure for inside mount blinds?

Inside mount blinds are installed within the window frame. Start by measuring the width at the top, middle, and bottom of the window. Take the smallest measurement and write it down. Next, measure the height at the left, center, and right side of the window, and again, record the smallest measurement.

4. How do I measure for outside mount blinds?

Outside mount blinds are installed outside the window frame, either on the wall or above the window. Measure the width from the outermost points where you want the blinds to hang. Add a few inches on each side to ensure proper coverage. For the height, measure from the desired top position to the bottom of the window or beyond, depending on your preference.

5. What if my windows are not perfectly square?

If your windows are not perfectly square, it is recommended to measure the width and height in multiple places and use the smallest measurement. This ensures that the blinds fit properly and operate smoothly.

6. Do I need to consider any obstructions or handles?

Yes, it is important to consider any obstructions such as window handles, locks, or trim when measuring your windows. Make sure to measure around them or take them into account when determining the width and height.

7. Should I measure each window individually?

Yes, it is advisable to measure each window individually, even if they appear to be the same size. Windows can vary slightly in size, especially in older homes, so measuring each window ensures a precise fit.

8. Can I measure for blinds on my own, or should I seek professional help?

Measuring for blinds can be done on your own with the right tools and guidance. However, if you are unsure or have complex window configurations, seeking professional help can ensure accurate measurements and a hassle-free installation.

9. Any additional tips for measuring windows?

Always double-check your measurements before purchasing blinds. It is also a good idea to take note of any special requirements or preferences, such as blackout blinds or cordless options, to ensure you select the right blinds for your needs.


Measuring your windows accurately is a crucial first step in choosing the perfect blinds. By following these simple guidelines and taking accurate measurements, you can ensure that your blinds fit perfectly and enhance the overall look of your space.
