How to measure correctly

Measuring instructions for different installation variants with a rectangular window shape

As our pleated and honeycomb blinds are individually made to measure, we need measurement details that are as accurate as possible. Regardless of the type of installation, attention must be paid to the following points:

  • Take measurement at multiple points
    Measure the height and especially the width at multiple points. Especially when installing directly in front of the glass (on the glazing bead), it is possible, for example, for the width at the top, in the middle and at the bottom to vary slightly. In this case take the narrowest width as the measurement.
  • Measure each window individually
    At first sight many windows appear to have identical measurements. Nevertheless, take the time to measure all windows individually – especially when installing directly in front of the glass.
  • Use a metal tape measure to measure up
    From our experience the most suitable aid to use for measuring up is a metal tape measure. However, a ruler / folding rule is similarly well suited to the task. Sewing tape measures made of flexible material can, on the other hand, lead to small inaccuracies.
  • Ordering dimensions = the dimensions of the pleated blind
    Please note: the measurements given when placing the order are the measurements of the finished pleated blind. The pleated blind units are made with millimetre precision based on the figures you provide, without any deductions being made in our production operation. Especially where installation is to be directly in front of the glass, you should ensure that the measurements you provide are not too wide.


The width and height must be determined differently depending on the type of installation. Please measure as carefully as possible and always state the measurements from inside to outside.
