How to measure for Blinds

Step 1: Decide on Fitting Style

Choose whether you want the blinds to fit inside the window recess (inside mount) or outside the window recess (outside mount).

Step 2: Gather Tools

You will need a metal tape measure, a notepad, and a pen.

Step 3: Measuring Inside the Window Recess (Inside Mount)

  1. Measure the width of the window recess at the top, middle, and bottom. Write down the measurements in millimeters (mm) and use the smallest width.
  2. Measure the height of the window recess on the left, middle, and right. Write down the measurements in millimeters (mm) and use the smallest height.

Step 4: Measuring Outside the Window Recess (Outside Mount)

  1. Measure the exact width you want the blinds to cover, including any extra overlap. Measure at the top, middle, and bottom, and use the largest width.
  2. Measure the exact height you want the blinds to cover, including any extra overlap. Measure at the left, middle, and right, and use the largest height.
