🌱 Child growth
Plot your child on the official WHO growth charts from birth to 19: z-score, percentile and nutrition classification, with every measurement saved to trace the growth path.
Curves P3 · P15 · P50 · P85 · P97 per WHO. Saved measurements join into your child's growth path.
Enter birth date, weight and height to get weight-for-age, height-for-age and BMI-for-age at once, and see the dot land among the P3–P97 curves.
⚠️ Educational reference, not a substitute for a paediatric or nutrition consultation. Data: the official WHO LMS tables — Child Growth Standards (2006) for 0–60 months, joined with the Growth Reference (2007) for 5–19 years. Each index covers exactly the span WHO published, no extrapolation: weight-for-age 0–10 years (WHO drops it afterwards because puberty skews weight — BMI-for-age takes over), height-for-age 0–19, BMI-for-age 5–19. Length is measured lying down through month 24, standing height afterwards (the standard already accounts for the −0.7 cm difference). Classification per WHO: weight-for-age below −2 SD = underweight, below −3 SD = severe; height-for-age below −2 SD = stunting; BMI-for-age above +1 SD = overweight, above +2 SD = obese, below −2 SD = thin.
