Accurately Measuring Your Windows for Treatments

Choosing the right window treatments can transform any room, adding style, privacy, and light control. However, the key to a perfect fit lies in accurate measurements. Whether you’re installing blinds, shades, or curtains, knowing how to measure your windows correctly is essential. This guide will walk you through the process, ensuring your window treatments look professional and function flawlessly.

How to Measure Windows for Treatments: Essential Tips

Measuring windows might seem straightforward, but small errors can lead to treatments that don’t fit well or function properly. Here’s how to get it right:

• Use a steel tape measure for accuracy.

• Measure width and height separately for inside mount or outside mount options.

• Record measurements in inches to match most product specifications.

• Measure each window individually even if they look identical.

• Double-check your numbers before ordering.

  
  

Inside Mount vs. Outside Mount

Before measuring, decide if you want an inside mount (treatment fits inside the window frame) or an outside mount (treatment covers the window and some wall space). This choice affects how you measure.

• Inside Mount: Measure the exact width and height inside the window frame.

• Outside Mount: Measure the area you want to cover, usually wider and taller than the window frame.

  
  

Step-by-Step Measuring Process

1. Width Measurement

2. For inside mount, measure the width at the top, middle, and bottom of the window frame.

3. Use the narrowest measurement to ensure the treatment fits.

4. Height Measurement

5. Measure from the top inside edge of the frame to the sill or bottom edge.

6. For outside mount, measure from where you want the treatment to start to where you want it to end.

7. Depth Measurement

9. Check the window frame depth to ensure your treatment will fit inside without obstruction.

What Size Curtains Do I Need for a 72 Inch Window?

When you have a 72-inch wide window, selecting the right curtain size is crucial for both aesthetics and functionality. Curtains should be wider than the window to allow for fullness and proper coverage.

Calculating Curtain Width

• Fullness Factor: Curtains typically require 1.5 to 3 times the width of the window for a rich, gathered look.

• For a 72-inch window:

- Minimum width = 72 inches x 1.5 = 108 inches total curtain width.

- Maximum width = 72 inches x 3 = 216 inches total curtain width.

You can divide this width between two panels or more, depending on your style preference.

Curtain Length Options

• Sill length: Curtains end at the window sill.

• Below sill: Curtains extend a few inches below the sill.

• Floor length: Curtains reach the floor, ideal for a formal look.

• Puddling: Curtains extend onto the floor for a dramatic effect.

  
  

Measure from the curtain rod to your desired length point.

Curtain Rod Placement

• Mount the rod 4-6 inches above the window frame to create the illusion of height.

• Extend the rod 3-6 inches beyond each side of the window to allow curtains to be pulled fully open without blocking the window.

Tips for Measuring Odd-Shaped or Large Windows

• For bay or bow windows, measure each individual window section.

• Take multiple measurements and note any irregularities.
