13 year old girl — height and weight
Percentiles from the IAP 2015 revised growth charts. These describe a population; they do not assess a child.

What the wall chart shows at 13 years
138.2–165.9cm
Ninety-four healthy girls in every hundred at 13 years measure somewhere inside that band — a spread of 27.7 cm. The median sits at 152.2 cm, and the median weight at 43.6 kg. Being anywhere in the shaded channel is the ordinary case, not a finding.
What this page cannot tell you is where one particular child belongs on it, or what a position means for them. That reading needs several visits plotted together, the parents' heights, and a paediatrician.
How a measurement becomes a percentile
- Take the child's age in completed years and their sex. Both change the curve, so a chart read against the wrong one is simply the wrong chart.
- Open the reference built for that age band: the WHO 2006 standards to five years, the IAP 2015 revision from five to eighteen. This page uses IAP సవరించిన ఎదుగుదల చార్టులు, 2015 సవరణ.
- Read the height across the row for that age. The published percentile columns are the answer; the value between two columns is not computed here, because interpolating a growth curve produces a figure that appears in no reference.
- Place the reading inside the 3rd–97th channel drawn above. The position is a rank in a population — nothing more is claimed by it.
- Repeat at the next visit. The line joining the readings is the measurement that matters clinically; a single dot is not.
percentile = rank of this height among 100 girls aged 13 years (published IAP 2015 table value — never interpolated)

What these numbers mean
The 50th percentile is the middle of the reference population, not a target to reach. Half of all healthy girls at 13 years measure below it. A child on the 3rd percentile and a child on the 97th percentile are both, on this evidence alone, growing normally.
What a paediatrician actually reads is the shape of the line over time. Children settle onto their own channel and then follow it, and it is a change in that channel — not its height on the page — that prompts a closer look. Two measurements a year apart, plotted, carry more information than any single number compared with this table.
If you are worried about your child's growth, take the measurements to a paediatrician rather than to a website. That is not a disclaimer for our benefit; it is genuinely the only way to read these numbers properly.

Questions parents ask at this age
What is the average height of a 13-year-old girl?
The median (50th percentile) height for a 13-year-old girl in the IAP 2015 revised growth charts is 152.2 cm. Half of healthy girls that age measure above that and half below. The 3rd to 97th range is 138.2 cm to 165.9 cm — which is how wide "normal" genuinely is at this age.
What is the average weight of a 13-year-old girl?
The median weight is 43.6 kg, with the 3rd to 97th percentile range running from 28.9 kg to 67.1 kg. Weight varies more than height does at every age, and it responds to a recent illness or a growth spurt far more quickly.
My girl is below the 50th percentile — is that a problem?
No. Half of all healthy children are below the 50th percentile; that is what a median is. Growth is assessed by whether a child is following their own curve consistently over time, together with parental heights, feeding and general development. A paediatrician reading a plotted chart can tell you that. A single measurement compared to a table cannot.
Which chart is this from?
IAP 2015 revised growth charts. The Indian Academy of Pediatrics published these revised charts in 2015 from measurements of contemporary Indian children, and they are the recommended reference for Indian children aged 5 to 18.
Percentile values reproduced without modification from the IAP 2015 revised growth charts (2015 revision); transcription last checked JUL 2026. General information only — not medical advice. Growth varies enormously between healthy individuals; a single measurement means little. Discuss any concern about a child's growth with a paediatrician.
