WHO growth charts are standardized tools developed by the World Health Organization to track child growth and development. They show how children of the same age and gender typically grow in weight and height, helping parents and doctors identify if a child is growing normally.
Growth percentiles indicate where your child falls compared to other children of the same age and gender. For example, if your child is in the 50th percentile for weight, they weigh more than 50% of children their age and less than the other 50%. Percentiles between the 25th and 75th are typically considered normal.
While growth patterns vary, you should consult your pediatrician if your child consistently falls below the 3rd percentile or above the 97th percentile, or if there's a sudden change in their growth pattern. Remember that healthy children come in all sizes, and one measurement doesn't tell the whole story.
For infants, growth is typically tracked at each pediatric visit (usually monthly for the first 6 months, then less frequently). You can track growth at home monthly or whenever you're curious about your child's development. Consistent tracking helps identify growth patterns over time.
WHO growth charts are based on data from healthy, well-nourished children from diverse ethnic backgrounds around the world. They represent optimal growth under ideal conditions. However, individual children may naturally grow at different rates, and factors like genetics, nutrition, and health conditions can influence growth.
Length is measured with the child lying down (typically for children under 2 years), while height is measured standing up (for children 2 years and older). Our calculator automatically uses the appropriate measurement type based on your child's age.
