Ideal Body Proportions Calculator

Classical aesthetic targets from Steve Reeves and the Greek ideal, calculated from your wrist circumference and height.

Classical body proportions (the "Grecian ideal") target a shoulder-to-waist ratio of 1.618 (golden ratio), arms ≈ neck, calves ≈ arms, and chest ≈ thigh × 2. These are aesthetic frameworks, not health requirements.

Steve Reeves "Classic Physique" proportions

  • Arms = Neck = Calves
  • Chest = Pelvis × 1.65
  • Waist = 70% of pelvis
  • Thighs = Pelvis × 0.85

The Adonis Index (shoulder : waist)

A shoulder-to-waist ratio of 1.618 (φ, the golden ratio) is the most-cited "ideal." Reeves himself sat at ~1.62. For most men, 1.5 is achievable; 1.6+ is rare and requires both lean build and developed delts.

Frequently asked questions

Are these proportions actually achievable?
For most people, the upper-body ratios (especially the 1.618 shoulder-to-waist) require both leanness and substantial lateral delt + lat development. Steve Reeves trained for decades on a high-volume program to reach his numbers.
Should I train to hit these proportions?
They're a useful framework if aesthetics are your goal, they describe what looks balanced. They're not health requirements. Health depends on body composition (body fat, lean mass) and cardiovascular fitness, not ratios.
