Shoulder-to-waist ratio: a simple “V-taper” metric

The shoulder-to-waist ratio compares your shoulder circumference (or shoulder width proxy) to your waist circumference:

Shoulder-to-waist ratio = shoulders ÷ waist

It’s not a health diagnosis. It’s a way to track proportions when your goal is a more pronounced upper-body “V”.

How to measure (to avoid fake progress)

Consistency matters more than the exact spot:

  • Shoulders: measure around the widest part of the shoulders/upper torso (repeat the same placement).

  • Waist: pick a consistent point (navel or narrowest) and stick to it.

  • Tape snug, not tight; measure after normal exhale.

How to use the ratio

Track it as a trend:

  • Re-measure weekly or every 2 weeks
  • Use the same time of day and similar conditions
