The measurement is taken from the outside of each peg. ATA Specs say that a bow should be properly braced with a string that measures 3â³ shorter than the bow. So if a bow is 60â³ is should be braced properly with a string measuring 57â³ under 100 lbs of tension after 20 seconds. Bowstrings for bows of less than 40 lbs should be measured in the same manner, using 50 lbs of tension.
