About the Ideal Weight Calculator

The Ideal Weight Calculator estimates a healthy body weight range for your profile. Enter your height, age, gender, and body frame to see target weight figures you can compare at a glance.

The calculator applies several established formulas, including the Devine formula, the Robinson formula, and the Hamwi formula. Each formula starts from height and adjusts for gender, and the calculator also factors in age and body frame size to refine the estimate. Compare all results side by side instead of relying on a single number. For personal health decisions, consider consulting a healthcare professional.

  • Select your gender and enter your height in feet and inches or centimeters.
  • Enter your age and choose a body frame size: small, medium, or large.
  • Review the results table and use the range of values as your reference.
