Ideal Weight Calculator

Compare Devine, Robinson, Miller, and Hamwi adult reference estimates, plus their transparent arithmetic average. These height-and-sex formulas do not measure health, body composition, ethnicity, disability, age, or personal goals. Calculate it clearly with Figur.

How the ideal weight calculator works

Compare Devine, Robinson, Miller, and Hamwi adult reference estimates, plus their transparent arithmetic average. These height-and-sex formulas do not measure health, body composition, ethnicity, disability, age, or personal goals.

Method and assumptions

Figur converts adult height to inches above 5 feet and reports Devine, Robinson, Miller, and Hamwi formulas; it also shows their unweighted arithmetic average.

  • The formulas apply from a 5-foot baseline, and Figur does not extrapolate them below that height.
  • They are historical height-and-sex references, not measures of health or body composition and not a clinical target.
  • The displayed average gives all four formulas equal weight and does not imply clinical consensus.

Worked example

An adult woman is 165 cm tall.

The four-formula average is 57.7 kg, with every individual estimate shown.

Frequently asked questions

Why are there several estimates?

The formulas use different historical assumptions, so they give different reference weights. The average is not a clinical target.

Why is height under 5 feet rejected?

These four formulas are conventionally defined from a 5-foot baseline. This calculator does not extrapolate them below that baseline.
