How to Measure Windows for Drapery: Step-by-Step Video Guide

To measure windows for perfectly fitting drapery, start by gathering a steel tape measure, a notepad, and a pencil. Begin with the width: measure across the top, middle, and bottom of the window, noting the widest measurement. Next, measure the height from the top of the window to the sill, recording the longest measurement. For outside-mounted drapery, add extra inches to your measurements for added coverage and aesthetic appeal. Accurately measuring your windows is crucial to ensure that your drapery fits perfectly and enhances the overall look of your space.

Tools You’ll Need

Tools For Measuring Curtains

Before you begin, gather these essential tools:

  • Measuring Tape: A retractable steel tape is ideal for accuracy.
  • Step Ladder: Necessary for reaching higher windows.
  • Notepad and Pen: For jotting down measurements.
  • Metal Ruler: For checking the straightness of window frames.

Having these tools on hand ensures you’re well-prepared to measure your windows accurately.

Step-by-Step Guide to Measuring Windows

Measuring the width of your window correctly is crucial for ensuring your drapery fits perfectly. Here’s how to do it:

  1. Inside Mounts: Measure the inside width of the window frame at the top, middle, and bottom. Use the narrowest measurement.
  2. Outside Mounts: Measure the width you want the drapery to cover, typically extending beyond the window frame to create a fuller look.

Measuring Length

The length of your drapery can dramatically affect the look of your room. Here’s how to measure it:

  1. Different Drapery Styles: Measure from the top of the window frame (or the point where the rod will be mounted) to the desired length. For floor-length drapery, measure to just above the floor. For sill-length, measure to just below the sill.
  2. Considerations for Drapery Length: Take into account whether you want your drapery to puddle on the floor or hang just above it. This decision will affect your measurements.

Using Everyday Objects for Measurement

If you don’t have a measuring tape, you can still get accurate measurements using everyday objects:

  1. Standard Sheet of Paper: Use an 8.5 x 11-inch sheet of paper. Mark off each length and add them up.
  2. Ruler or Yardstick: A ruler or yardstick can be a handy alternative. Measure in sections and record each measurement.
  3. String or Yarn: Wrap string or yarn around the window dimensions, then measure the string with a standard ruler.

Tips for Ensuring Accuracy

  • Double-Check Measurements: Verify your measurements with multiple objects to ensure consistency.
  • Avoid Common Pitfalls: Be mindful of stretching the string or misaligning the ruler, as these can lead to inaccuracies.

Measuring for Drapery Rods and Hardware

Measuring For Drapery Rods and Hardware

Accurate measurement for drapery rods and hardware is essential for a perfect fit. Here’s how to do it:

  1. Positioning: Decide where you want the rod to be mounted. Higher mounts can make windows appear taller.
  2. Measuring for Rods: Measure the width of the window plus the desired overhang for the rod. This overhang allows the drapery to fully cover the window when closed.
  3. Brackets and Hardware: Ensure you account for the space needed for brackets and any additional hardware.

Special Considerations for Different Window Types

Measuring for Bay Windows

Bay Window Measurement

Bay windows add a unique architectural element to your space but can be tricky to measure. Here’s a step-by-step guide:



  1. Measure Each Section: Measure the width and height of each individual section of the bay window.
  2. Angled Sections: Measure the angles where the windows meet. This ensures the drapery fits the entire bay window area accurately.

Measuring for Arched and Specialty Windows

Arched Window Measurement

Arched and specialty windows can be beautiful focal points. Here’s how to measure them:

  1. Measure the Widest Part: Measure the width at the widest part of the arch.
  2. Measure the Height: Measure from the base to the highest point of the arch.
  3. Custom Solutions: Consider custom drapery options to fit the unique shape perfectly.

Common Mistakes to Avoid

Avoid these common measurement mistakes to ensure your drapery fits perfectly:

  1. Not Double-Checking Measurements: Always verify your measurements. One mistake can lead to ill-fitting drapery.
  2. Ignoring Hardware Space: Don’t forget to account for the space needed for drapery rods and brackets.
  3. Incorrect Mount Type Measurements: Ensure you differentiate between inside and outside mount measurements for accuracy.

Custom vs. Ready-Made Drapery Measurements

Understanding the differences in measurement techniques for custom and ready-made drapery can help you decide which option is best:

  1. Custom Measurements: Tailored to your specific window dimensions, ensuring a perfect fit. Ideal for unique window shapes or sizes.
  2. Ready-Made Measurements: Follow standard sizes. Convenient but may not fit perfectly if your windows are not standard sizes.
