Paediatric weight estimate (APLS)

1-5 years: 2 × age + 8. 6-12 years: 3 × age + 7.

Age

years

Estimated weight

16 kg

Formula

2 * age + 8 + older * (age - 1)

Notes

Infants < 12 months: (0.5 × age in months) + 4. Tick 'Age 6-12 years' for older children (formula becomes 3 × age + 7). Use measured weight or a length-based tape (Broselow) when available; Indian children are often lighter than these UK-derived estimates.
