Measuring Roller Blinds Like A Pro

Published June 18, 2024

Measuring for roller blinds is a crucial step to ensure a perfect fit. Accurate measurements can make the difference between blinds that enhance the aesthetics of your space and ones that fall short. In this comprehensive guide, we will walk you through the process of measuring the width and drop of your window recess, ensuring you achieve the best results for your roller blinds.

Importance of Accurate Measurements

Accurate measurements ensure that your roller blinds fit seamlessly within your window recess. Poorly fitted blinds can result in light leakage, reduced privacy, and an overall unsatisfactory appearance. By following these measurement steps, you can avoid these issues and enjoy the full benefits of your roller blinds.

Tools You Will Need

  • Measuring tape (preferably metal for accuracy)
  • Pencil and paper
  • Step stool or ladder (if necessary)

How to Measure the Width of the Window Recess

Measure at the Top

Begin by measuring the width of the window recess at the top. Place your measuring tape inside the recess and measure from one side to the other. Write down this measurement.

Measure at the Middle

Next, measure the width at the middle of the window recess. This ensures that you account for any variations in the width. Again, record this measurement.

Measure at the Bottom

Finally, measure the width at the bottom of the window recess. Write down this measurement as well.

Determine the Narrowest Width

Compare the three measurements you have taken (top, middle, and bottom). Use the narrowest measurement for the width of your roller blinds. This ensures that the blinds will fit within the narrowest part of the recess, preventing any gaps.

How to Measure the Drop of the Window Recess

Measure from the Top to the Sill

Measure the drop of the window recess by placing your measuring tape at the top of the recess and measuring down to the windowsill. Record this measurement.

Consider Multiple Points

To ensure accuracy, measure the drop at several points across the width of the window recess (left, centre, and right). This accounts for any variations in height.

Determine the Longest Drop

Compare the measurements you have taken and use the longest measurement for the drop of your roller blinds. This ensures that the blinds will cover the entire height of the recess, providing full coverage.

Practical Tips for Measuring Roller Blinds

  • Always double-check your measurements: To avoid mistakes, measure twice and write down each measurement clearly.
  • Measure in millimetres: Using millimetres can provide more precise measurements than centimetres or inches.
  • Account for obstructions: Be mindful of any handles or obstructions within the window recess that may affect the fitting of the blinds.


By following these detailed steps, you can measure your window recess accurately, ensuring that your roller blinds fit perfectly. Accurate measurements not only enhance the look of your space but also improve the functionality of your blinds, providing better light control and privacy.
