What is the shoulder-to-waist ratio?
The shoulder-to-waist ratio divides shoulder circumference by waist circumference. Values around 1.6 for men and 1.4 for women correspond to what researchers call the "Adonis Index" — an aesthetic reference based on the golden ratio applied to the human body.

This index does not measure health, but visual proportion. It is widely used by bodybuilders and fitness enthusiasts to track the evolution of a V-taper physique. Learn more

Measurement History

Understand your
body proportion

The science and aesthetics behind SymScore.

The Adonis Index

The "Adonis Index" concept relates shoulder circumference to waist circumference, seeking the proportion that Renaissance artists and ancient Greeks associated with the ideal male body. For women, the focus is similar — shoulders slightly wider than the waist.

The golden ratio in the body

The ratio φ (phi) ≈ 1.618 appears in many natural proportions. When applied to the human body, it suggests that shoulders ~1.6× wider than the waist (men) create a visual perception of greater attractiveness and strength. For women, ~1.4× is the most cited reference.

These values are classic aesthetic references, not medical rules.

How to measure correctly

Shoulders: Measure around the widest point of the shoulders, passing over the lateral deltoids, with arms relaxed at your sides.

Waist: Measure around the narrowest point of the torso, usually above the navel, without holding your breath.

  • Calculated scores and history
  • Preferences such as unit (cm/in) and gender selection

This data is stored exclusively in your browser's localStorage and never transmitted to our servers.

Automatically collected information:

  • Basic analytics data such as page views, device type, and browser (collected anonymously)

Important: SymScore does not provide medical advice, diagnosis, or treatment. The scores and measurements generated by this app are for aesthetic and informational purposes only. Always consult a qualified healthcare professional before making decisions about your physical health or fitness.

The shoulder-to-waist ratio and Adonis Index are aesthetic references, not clinical standards. Individual body composition, health, and fitness cannot be accurately assessed through these measurements alone.
