Child Growth Chart ஐ எப்படி கணக்கிடுவது
Child Growth Chart என்றால் என்ன?
A child growth percentile calculator plots a child’s height, weight, and head circumference against WHO (0–2 years) or CDC (2–20 years) growth curves. A child at the 50th percentile is exactly average; the 75th percentile means they are larger than 75% of children the same age and sex.
சூத்திரம்
Percentile = Position on WHO/CDC growth curve for age and sex
- H
- Height/Length (in or cm) — Child’s measured height or recumbent length
- W
- Weight (lbs or kg) — Child’s weight
- HC
- Head Circumference (in or cm) — Circumference of child’s head at widest point
- P
- Percentile (%) — Position on growth curve relative to same-age peers
படிப்படியான வழிகாட்டி
- 1Measure the child’s height, weight, and/or head circumference accurately
- 2Plot the measurement on the appropriate growth chart for age and sex
- 3Identify the percentile by seeing which curve the measurement falls on
- 4Track percentiles over time — consistent tracking along a curve is more important than any single reading

தவிர்க்க வேண்டிய பொதுவான தவறுகள்
- ✕Using CDC charts for children under 2 (WHO charts are recommended for 0–2 years)
- ✕Panicking about a single measurement instead of tracking the trend over multiple visits
- ✕Comparing siblings — each child has their own growth pattern
அடிக்கடி கேட்கப்படும் கேள்விகள்
What percentile is considered normal?
Any percentile from 3rd to 97th is generally considered within the normal range. What matters more is whether the child consistently follows their own growth curve over time.
When should I worry about growth?
Consult a pediatrician if a child crosses two or more major percentile lines (e.g., drops from 75th to 25th), falls below the 3rd percentile, or has a significant discrepancy between height and weight percentiles.
