Body Type Calculator

Body type analysis combines skeletal frame size with distribution of weight to suggest training and nutrition approaches — not to label you permanently, but to personalize starting points. This calculator uses three complementary methods depending on sex.

Frame size compares wrist circumference to height. Women with wrist ÷ height below 0.093 have a small frame; 0.093–0.10 is medium; above 0.10 is large. Men use thresholds 0.095 and 0.105. Frame size influences healthy weight ranges and ideal-weight formulas.

For women, bust, waist, and hip measurements classify body shape: hourglass (balanced bust/hips, narrow waist), pear (hips wider than bust), apple (weight around midsection), rectangle (similar measurements), or inverted triangle (broader shoulders/bust). Percent-difference rules compare circumferences relative to each other.

For men, BMI plus estimated body fat % suggests somatotype: ectomorph (lean, hard to gain), mesomorph (athletic, builds muscle easily), or endomorph (stores fat more readily). Each type includes tailored exercise and nutrition guidance — higher surplus for ectomorphs, balanced macros for mesomorphs, and calorie control with cardio emphasis for endomorphs.

Body shape and somatotype shift with training, diet, and age. Use results as orientation, not destiny. Pair with body fat and BMI calculators for fuller context.
