Baby Weight & Height Chart (0-5 Years): Tracking Normal Growth
Every new parent asks the same question sooner or later: is my baby growing at a healthy rate? Weight and height aren't just numbers — they're one of the clearest indicators of a child's overall nutrition and health. This guide walks through average weight and height by age, based on WHO (World Health Organization) growth standards, and explains when a check-up is worth scheduling.
At birth
A full-term baby typically weighs between 2.5 kg and 3.5 kg, with a length of roughly 45-55 cm. It's normal for weight to dip slightly in the first few days (up to 5-10%) — this usually recovers within two weeks.
0-12 months: the first year
- 3 months: weight starts approaching double the birth weight
- 6 months: average weight 7-8 kg, height 65-67 cm
- 12 months: average weight 9-10 kg, height 74-76 cm — roughly triple the birth weight
Growth is fastest during this stage, which is why pediatricians track weight and height at nearly every monthly visit.
1-5 years: toddler to preschooler
- 2 years: average weight 12-13 kg, height 85-88 cm
- 3 years: average weight 14-15 kg, height 94-97 cm
- 4 years: average weight 16-17 kg, height 100-103 cm
- 5 years: average weight 18-19 kg, height 108-110 cm
Growth slows down somewhat during this period but should remain steady. Every child's pattern varies a bit based on genetics, nutrition, and health — so treat these numbers as a guideline, not a strict rule.
When to see a doctor
If your child's weight or height plateaus for 2-3 months, or falls well below the growth chart (below the 3rd percentile), it's worth consulting a pediatrician. Regular growth monitoring helps catch nutrition gaps, hormonal issues, or other concerns early.
Tips to support healthy growth
- An age-appropriate, balanced diet — protein, iron, calcium, and vitamins
- Exclusive breastfeeding for the first 6 months, then continued alongside solids
- A consistent sleep schedule — growth hormone is released mostly during sleep
- Outdoor play and physical activity
- Timely vaccinations and regular check-ups
