My digital piano has a separate pedal block that can be placed at any distance from the keyboard. However I think makes a lot of sense to position it in a standard way, how it is typically positioned. As it tends to slide, I am now screwing it to the floor and need to know the recommended location.

What is a typical standard distance of the piano pedal block, measured from the front of the white keys to the tip, or root, of the pedals?
