The duty cycle is measured as a percentage of the total period of the square wave. You can also describe this as time between the rising edge and the falling edge of the square wave. I don't think that "the total length between 2 leading edges" was concise enough.

I'm sure there're other threads that explain the fundamentals of PWM, PPM, and whatever else.
