Coverage width in cms

Measure the flat width between two rod supports(brackets). Please don’t consider the pleat. The extra pleat calculation & consumption we will take care.
If it’s for track, same like above. Please provide us one end to other end of track as width measurement. Follow same for both American pleat & Eyelet Curtains.
 
For eg: If the entered width is 130cms, we will be providing 2 curtains of 65cms each in American pleat. Here the pleats will be fixed.

If the entered width is 130cms, we will be providing 2 curtains of 130cms each in Eyelet Curtains. Here the curtains will be flat.

Basically the coverage of both the pleats will be same.
