📊 Baby Growth Percentile Calculator
Check your baby's weight & height against WHO growth charts — free & instant
Quick Answer
Any weight or height between the 3rd and 97th percentile on WHO growth charts is medically normal for Indian babies. What matters more than the exact percentile is that your baby tracks consistently along their own curve over multiple check-ups. IAP and WHO use the same MGRS reference charts for all Indian children aged 0–5 years.

⚕️ Medical Disclaimer: This calculator uses WHO Multicentre Growth Reference Study (MGRS) data and is for informational purposes only. Growth percentiles are a screening tool — they do not diagnose any condition. A single measurement is less important than your baby's growth trend over time. Always discuss your baby's growth with a qualified paediatrician.
Frequently Asked Questions
What is a healthy percentile for my baby?
Any percentile between the 3rd and 97th is within the normal range according to WHO and the Indian Academy of Pediatrics (IAP). There is no single "ideal" percentile — a baby consistently at the 15th percentile who tracks along that curve is growing perfectly. Concern arises when a baby crosses two major percentile bands downward over time.
My baby is small — should I be worried?
Not necessarily. Genetics plays a large role — small parents often have small babies. What matters most is the growth trend across multiple measurements. If your baby is feeding well, active, reaching developmental milestones, and tracking their own percentile curve, they are likely healthy. Talk to your paediatrician if you notice a significant drop across percentile lines.
How often should I weigh my baby?
The IAP recommends weight checks at every vaccination visit — at birth, 6 weeks, 10 weeks, 14 weeks, 6 months, 9 months, 12 months, 15 months, 18 months, and 24 months. Between visits, weigh your baby if you have concerns about feeding or illness.
Which growth chart does India follow?
India follows the WHO Multicentre Growth Reference Study (MGRS) charts, endorsed by the Indian Academy of Pediatrics (IAP). These charts were built from data on healthy breastfed babies from 6 countries including India, Brazil, Ghana, Norway, Oman, and USA.
👩⚕️ What Paediatricians Say About Baby Growth
According to IAP guidelines, Indian paediatricians use WHO Multicentre Growth Reference Study (MGRS) charts for children aged 0–5 years. A single low reading is far less significant than a consistent downward crossing of two major percentile lines.
- Breastfed babies often track slightly below formula-fed babies in weight — this is normal and expected per WHO charts
- Head circumference growth is a critical early neurological indicator — IAP measures it at every visit in the first year
- Concern arises when a baby consistently falls below the 3rd percentile or crosses two major lines downward over 2+ visits
- A single illness causing temporary weight loss does not indicate a growth disorder
