Every child grows at their own pace, and healthy growth is influenced by genetics, nutrition, physical activity, sleep, and overall health. One of the tools healthcare professionals use to monitor a child's growth is the Body Mass Index (BMI).
Body Mass Index (BMI) is a calculation based on a child's height and weight. Rather than using a fixed number, children's BMI is compared with growth charts to determine whether they are within a healthy range for their age and sex. BMI is only a screening tool and should always be interpreted by a healthcare professional along with the child's overall growth, development, and medical history. This guide shows factors that affect a child's BMI.

Consult a healthcare professional if your child:
| BMI Percentile | Weight Category | What It Means |
|---|---|---|
| Below 5th percentile | Underweight | May indicate the child needs medical or nutritional evaluation. |
| 5th to Below 85th percentile | Healthy Weight | Considered a healthy BMI range for most children based on age and sex. |
| 85th to Below 95th percentile | Overweight | The child may be at increased risk of weight-related health problems. |
| 95th percentile and Above | Obesity | A healthcare provider should evaluate the child's growth and overall health to recommend appropriate care. |
A healthy BMI for children depends on their age and sex. Healthcare providers use a Children's BMI Chart to compare your child's BMI with others of the same age and gender. A BMI between the 5th and 85th percentile is generally considered a healthy range.
Unlike adults, children's bodies are constantly growing and developing. Their BMI changes with age and differs between boys and girls, so pediatricians use age- and sex-specific growth charts instead of fixed BMI ranges.
BMI is a useful screening tool but not a complete measure of health. It helps identify potential weight concerns, but factors such as diet, physical activity, genetics, growth patterns, and overall health should also be considered.
Children aged 6–17 years should aim for at least 60 minutes of moderate to vigorous physical activity every day. Activities like running, cycling, swimming, dancing, and outdoor games help support healthy growth and maintain a healthy weight.
Avoid putting your child on a restrictive diet unless advised by a healthcare professional. Instead, encourage balanced meals, healthy snacks, regular physical activity, and positive eating habits to support healthy growth.
You should consult a healthcare provider if your child's weight changes rapidly, their BMI falls outside the healthy percentile range, or you notice concerns such as poor growth, low energy, breathing difficulties, or other health problems.
If your child's weight is significantly above or below the recommended range, or if there are underlying medical concerns, a pediatrician can assess your child's growth and recommend appropriate treatment or refer you to a pediatric dietitian or specialist if needed.
