One of the first details parents often hear after birth is how much their baby weighs. While every baby is different, understanding average birth weight can help provide reassurance.
Here are 5 essential facts about average baby birth weight in the UK.
1. The average birth weight in the UK
Most babies born in the UK weigh between 3.3kg and 3.5kg (around 7lb 4oz to 7lb 11oz).
2. Birth weight varies naturally
Genetics, gestational age, and whether it’s a first baby can all influence weight.
3. Babies can be healthy at many weights
Being slightly above or below average does not automatically indicate a problem.
4. Weight is closely monitored after birth
It’s normal for babies to lose a small amount of weight in the first few days. Health professionals monitor this carefully.

5. Growth over time matters most
Steady growth, feeding, and alertness are more important than the number on the scales at birth.
