I always thought that there is no norm for standard sizes of windows
there are standard sizes. In Germany the base grid measure for masonry is
12,5cm (based on one standard brick 24x11.5x7.1cm (Normalformat)), openings are
+1cm. These are raw measures.
Just as doors come in standard sizes, so too do windows.
You can read the reasons why things come in standard sizes here

Of course you can get non standard sized windows and doors.. but they
cost more.
For firms supplying standard windows and there sizes see;
