Ideal Weight Range
Ideal body weight can be estimated using several well-known formulas. All are based on height and gender.
Metric formulas (height in cm): Convert cm to inches first: inches = cm / 2.54, then apply the formulas below using inches over 60 (5 feet).
Imperial formulas (height in inches):
Devine Formula (1974):
- Male:
50 + 2.3 × (height in inches - 60)kg - Female:
45.5 + 2.3 × (height in inches - 60)kg
Robinson Formula (1983):
- Male:
52 + 1.9 × (height in inches - 60)kg - Female:
49 + 1.7 × (height in inches - 60)kg
Miller Formula (1983):
- Male:
56.2 + 1.41 × (height in inches - 60)kg - Female:
