How do I determine what size glove is right for me?

ASTM D120 section 8.2 provides the measurements of the diameter of
the palm for manufacturers, measured at the midpoint of the palm, plus or minus 1⁄2”. Measure your hand by wrapping the tape all the way around your palm at the point shown to the right. This would equate to the probable size of glove to select. Personal preference for tightness and finger length will ultimately determine the size that you are most comfortable wearing.  Please see the attached glove sizing guide below.
