Enter an age and measurement to see the percentile.
An estimate from a single measurement, not medical advice. Percentiles are most meaningful plotted over time by your pediatrician — always go by their assessment of your baby’s growth.
About growth percentiles
What is a growth percentile?
A percentile compares your baby to other babies the same age and sex. If your baby’s weight is in the 60th percentile, they weigh more than about 60 out of 100 babies that age. It’s a position on a curve, not a grade — the 20th percentile is just as healthy as the 80th.
Which growth charts does this use?
It uses the WHO Child Growth Standards (0–5 years), the same reference many pediatricians use for babies and the exact tables built into the Plumi app. It covers weight, length/height, and head circumference for boys and girls.
What percentile is “normal”?
There’s no single right number — healthy babies sit all across the chart, from the 3rd to the 97th percentile. What pediatricians watch most is the trend over time: babies tend to follow their own curve. A sudden jump or drop across percentiles is worth a conversation, a steady low or high curve usually isn’t.
Is this a diagnosis?
No. This is an estimate from a single measurement, and home scales and tape measures aren’t exact. Your pediatrician plots growth over time on a proper chart — always rely on their assessment.
Calm days, gently remembered.
