How to Use Our Ideal Weight Calculator

What should you weigh? It is a common question without a single answer, but our Ideal Weight Calculator gives you a well-researched range based on multiple medical formulas.

Entering Your Details

  • Height -- Your standing height in feet/inches or centimeters.
  • Gender -- Male and female formulas differ due to typical body composition differences.
  • Frame Size -- Small, medium, or large. If unsure, measure your wrist circumference: under 6.5 inches (women) or under 7 inches (men) suggests a small frame.

What You Get

The calculator provides results from several respected formulas:

  • Devine Formula -- Widely used in pharmacology for drug dosing
  • Robinson Formula -- Modified version of the Devine formula
  • Miller Formula -- Generally produces a lower target weight
  • Hamwi Formula -- Often used in clinical nutrition

Each formula produces a slightly different number. The range across all formulas gives you a realistic target zone rather than a single "perfect" weight.

Keeping Perspective

Ideal weight formulas do not account for muscle mass, bone density, or individual body composition. An athlete with significant muscle may weigh more than the calculated ideal and be perfectly healthy. Use these numbers as a general guide, not an absolute target.

The most important weight-related health indicator is the trend over time and how you feel, not a specific number on the scale.
