How To Measure Windows For Shades?

Before we delve into the specific steps of how to measure windows for shades, let’s understand why measuring your windows for shades is essential. Proper measurements guarantee that your shades will fit precisely, function effectively, and enhance the aesthetics of your room.

Steps to Measure Windows for Shades

Let’s now go into the specifics of evaluating your windows for shades. We’ll break the process down into simple steps and cover both interior and outdoor mounting.

Get Your Tools Ready:

Before you begin, make sure you have the necessary tools on hand. You’ll need a tape measure, pencil, and a notepad or smartphone to record measurements.

Inside-Mount Shades:

To measure for inside-mount shades, follow these steps:

  • a. Measure the width of the window frame from inside to inside. Take three measurements: at the top, middle, and bottom. Record the narrowest width.
  • b. Measure the height from the top of the frame to the windowsill. Again, record the shortest measurement.

Outside-Mount Shades:

If you’re opting for outside-mount shades, the process is slightly different:

  • a. Measure the width from the outside edge of the frame to the outside edge on both sides of the window. Take three measurements and record the widest width.
  • b. Measure the height from the top of the frame to where you want the shade to end. Record the desired height.

Recording Measurements:

Accurate recording is crucial. Make sure you note down all measurements clearly, and consider taking a photo of your window to help visualize the placement of the shades.

Tips and Considerations

Measuring for shades isn’t just about numbers; it involves various factors and considerations. Here, we’ll delve into essential tips and considerations to ensure your shades look and function their best.

  • Window Shape and Style: Discuss how different window shapes and styles can impact measurements, including irregularly shaped windows.
  • Window Treatment Type: Explain how the type of shade you choose (e.g., roller, cellular, Roman) may require specific measurement considerations.
  • Accuracy Matters: Emphasize that precision is key in measurements, and making assumptions about window dimensions can lead to fitting issues.
  • Consulting with Professionals: Highlight scenarios where seeking assistance from window treatment experts might be the best course of action.

Common Mistakes to Avoid

In this section, we’ll cover some common mistakes that people make when measuring windows for shades and why it’s crucial to avoid them.

  • Not Double-Checking Measurements: Explain the consequences of relying on single measurements and why double-checking is essential.
  • Neglecting Frame Depth: Discuss the importance of measuring the depth of the window frame, which is often overlooked but critical for proper installation.

What Is Standard Size Window Shade?

Standard window shades come in various sizes to fit common window dimensions. However, keep in mind that not all windows are standard, so precise measurements are often necessary for a perfect fit.

How Much Wider Should Shades Be Than The Window?

For inside-mount shades, it’s essential to measure the width accurately and provide the manufacturer with the exact measurement. Manufacturers will typically make slight adjustments to ensure a proper fit. For outside-mount shades, adding an extra 2 to 3 inches on each side is a common practice to ensure full coverage and light blockage.

How To Measure For Roller Shades?

Measuring for roller shades follows the same general principles as mentioned above. Ensure you measure the width and height accurately, and note any specific guidelines provided by the manufacturer for roller shade measurements.

Is It Better To Close Shades Up Or Down?

The direction in which you close your shades depends on your specific preferences and needs. Closing them upward can provide more privacy while still allowing some natural light to filter through. Closing them downward blocks more light and provides greater room darkening.


Measuring windows for shades is a fundamental step in ensuring your window treatments fit perfectly and function as intended. Accurate measurements, consideration of window type and treatment, and avoidance of common mistakes are key to achieving the desired results. By following how to measure windows for shades guidelines, you’ll be well on your way to enhancing the beauty and functionality of your windows with perfectly fitted shades.
