Most manufacturers do it that way but not everyone does.isnt the measures taken by the 12th fret?
"Factory string setting for standard tuning starts at the bass side 2/32" (1.59 mm) to 5/64" (1.98 mm) and the treble side is 3/64" (1.19 mm) to 2/32" (1.59 mm) measured from the 12th fret to the bottom of the strings."
