Hopefully this is a quick question
When measuring an English saddle's seat size from the button to the center of the cantle, do you include the entire button in the measurement?
I always assumed it was to the middle of the button, but when I tried measuring the Wintec Dressage Pro that I've been borrowing for several years, the tape measure ended up reading 16.75" in the middle of the button. So, if the measurement includes the button, it would be 17". If you don't include the button it would be 16.5". If you are supposed to measure to the middle of the button maybe something's wrong with the saddle?
