String spacing is the distance between the strings......that would be perpendicular to your measurement for scale length. Not all guitars have the same "spacing" between strings and that can through one off.....especially when using the thumb and fingers for picking.

String spacing is a common term on the pedal steel and lap steel forums. My custom lap steels have the EXACT same scale length (24") and EXACT same string space (3/8") between strings......so I have no problems moving from one to the other.
