Proportionality of body — McCallum's formula

Expert methodist John McCallum created this formula. It's based on the wrist girth:

  1. 6.5 waist girth is a chest girth.
  2. Waist girth equals 70% of the chest.
  3. 53% of the chest equal to hip girth.
  4. Neck is equal to 37% of chest girth.
  5. Biceps are equal to 36% of chest girth.
  6. Lower leg is equal to 34%.
  7. Forearm girth is equal to 29% of chest girth.

This formula isn't correct for everyone because it suggests that the wrist's size strongly depends on the size of other human bones.
