Devine formula at common heights
| Height | Men | Women |
|---|---|---|
| 5 ft 0 in (152.4 cm) | 50.0 kg | 45.5 kg |
| 5 ft 4 in (162.6 cm) | 59.2 kg | 54.7 kg |
| 5 ft 8 in (172.7 cm) | 68.4 kg | 63.9 kg |
| 6 ft 0 in (182.9 cm) | 77.6 kg | 73.1 kg |
How it is calculated
50 kg + 2.3 kg × (height in inches − 60)
45.5 kg + 2.3 kg × (height in inches − 60)
BMI 18.5–24.9 (WHO) or 18.5–22.9 (Asian Indian) × height (m)²
The Devine formula was published in 1974 to estimate drug doses, not as a fitness target, and it takes no account of frame size or muscle. It is only defined from 5 ft (152.4 cm) upwards.
For everyday use, the healthy BMI range is the better guide: any weight inside it is considered healthy for your height.
