Use a steel tape
A rigid steel tape is far more accurate than fabric — accuracy down to the millimetre is what we need.
How to Measure
Accurate measurements are the difference between a window that's framed and one that's perfect. Choose your product below for our printable, illustrated measuring guide.
Pick your mount
Decide between inside (recess) and outside (face) mount before you start. The numbers differ.
Measure three times
For width, measure top, middle and bottom. Use the narrowest. For drop, measure both ends.
Record in millimetres
All Riva products are made to the nearest millimetre. Note inside vs outside next to each figure.
