Ideal Weight Calculator
Devine, Robinson and Miller formulas compared.
Three established formulas — the truth is usually a range, not a single number.
How to Use
- Choose units.
- Select gender and enter your height.
- Compare the Devine, Robinson and Miller estimates.
Calculation Method
All three formulas use height above 5 ft (60 in):
- Devine: men 50 + 2.3·(in over 60); women 45.5 + 2.3·(in over 60) kg
- Robinson: men 52 + 1.9·…; women 49 + 1.7·… kg
- Miller: men 56.2 + 1.41·…; women 53.1 + 1.36·… kg
Treat the spread as a healthy target range, not a single number.
