About bridge & tailpiece measurements:
String spread is the distance between the centers of the outer strings on a bridge or tailpiece.
Saddle radius determines the arc formed by all the individual saddle heights, and is similar to the measurement of a fretboard.
Stud/post spacing is the distance between the centers of the mounting posts of a bridge or 'stop' tailpiece.
