About this calculator

Devine's 1974 formula was designed to dose medications, not to set beauty targets — yet it became the classic 'ideal body weight'. Treat its output as one anchor inside the broader healthy-BMI band shown beside it.

Formula

Devine: M = 50 + 2.3×(inches over 5 ft); F = 45.5 + 2.3×(inches over 5 ft).
Health metrics are informational estimates and are not a medical diagnosis.

Frequently Asked Questions

Which number should I target?

Aim anywhere inside the healthy BMI range where you feel strong and blood markers look good — not the single Devine figure.

Do formulas differ?

Robinson/Hammond/Miller variants tweak coefficients slightly; all land within a few kilograms of each other for common heights.
