The development of your beloved child is always a parent’s top concern. How do you know if your baby girl is growing up healthy and meeting standards? My Auris will help you answer this question with the WHO standard height and weight chart specifically for girls, making it easy for you to monitor and provide comprehensive health care for your child.
Standard Height and Weight Chart for Children
According to the World Health Organization (WHO), children’s height and weight vary by age and gender. To help parents easily monitor their child’s development, this article will guide you on how to consult the standard index chart for both boys and girls.
The chart consists of 3 columns: Boys, Age in months, Girls. When consulting, parents should cross-reference the “Age in months” row with the appropriate gender column to find their child’s standard measurements.
- TB (Average): The child is developing normally according to the standard.
- Above +2SD: The child may be overweight or obese (if considering weight) or very tall (if considering height).
- Below -2SD: The child is at risk of malnutrition, underweight, or stunting.
Below is a detailed table of children’s height and weight by age.

Average Height and Weight of Children
The physical development of young children is a remarkable journey, with significant changes in average height and average weight at each stage. Understanding these indicators helps parents effectively monitor their child’s height and weight growth.
Newborns: Right from birth, newborns have an average height of about 49.5 cm and an average weight of about 3.175 kg. These are foundational indicators for future development.
Children aged 12-24 months: Entering this stage, children undergo noticeable physical changes. Most babies will grow an additional 10-12 cm in height and gain about 2.27 kg in weight. Children also become stronger and more active.
Children aged 2-5 years: In the following years, from 2 to 5 years old, a child’s weight growth rate reaches about 1.996 kg per year. In terms of height growth, children grow about 8 cm between 2-3 years old and 7 cm between 3-4 years old. Notably, when children reach 24-30 months of age, their height often reaches half of their projected adult height.
Children aged 5-8 years: This stage marks stable development in average height and average weight. Children typically grow about 5-8 cm in height per year and gain 2-3 kg in weight per year until they enter puberty.

The Most Accurate Way to Calculate BMI
To accurately assess the physical development of children aged 0-59 months, parents should monitor their child’s growth based on the standard height and weight charts recommended by the National Institute of Nutrition and WHO (World Health Organization). For children aged 5-18 years, using the BMI calculation method will provide more accurate results in assessing childhood malnutrition or childhood obesity.
BMI Formula for Children Aged 5-18:
- Child BMI = Weight (kg) / (Height (m) x Height (m))
After calculation, compare the results with the standard BMI chart by age to determine the child’s nutritional status and growth:
- Average BMI: The child is developing normally.
- SD (Standard Deviation) Index
- SD (Standard Deviation) Index > 2SD: The child is overweight and obese.
Standard BMI Chart by Age for Children:
| Age | Average BMI for Boys | Average BMI for Girls |
| 5 | 15.3 | 15.2 |
| 6 | 15.3 | 15.3 |
| 7 | 15.5 | 15.4 |
| 8 | 15.7 | 15.7 |
| 9 | 16.0 | 16.1 |
| 10 | 16.4 | 16.6 |
| 11 | 16.9 | 17.2 |
| 12 | 17.5 | 18.0 |
| 13 | 18.2 | 18.8 |
| 14 | 19.0 | 19.6 |
| 15 | 19.8 | 20.2 |
| 16 | 20.5 | 20.7 |
| 17 | 21.1 | 21.0 |
| 18 | 21.7 | 21.3 |
Factors Affecting Children’s Height and Weight
Children’s height and weight are matters of great concern for many parents. A child’s physical condition is influenced by many factors, from genetics to living environment and nutrition. This article will analyze 6 important factors impacting physical development, helping parents better understand how to care for their young children’s health and support them in achieving ideal height and weight.
Genetic Factors
Pediatric genetics plays a crucial role in determining height and weight. According to pediatric specialists, children inherit genetic traits from both parents, including blood type, body fat percentage, and weight. A study published in the American Journal of Human Biology also confirms this.

Nutrition and Living Environment Affect Physical Condition
In addition to genetic factors, nutrition for height development is extremely important. Research by the United Nations University in Tokyo, Japan, shows that the living environment, especially nutrition, significantly affects a child’s physical condition. Providing adequate nutrients, especially calcium, iron, folic acid, and DHA, helps children improve their height. Conversely, environmental pollution and harsh climates can lead to delayed development.
Chronic Illnesses and Physical Development
Chronic illnesses and childhood growth disorders are closely linked. Serious illnesses, disabilities, or surgeries can negatively impact physical condition. A study in the National Medical Association Journal in January 2000 indicated that children with chronic conditions, such as sickle cell anemia, are often shorter and lighter than healthy children.
Parental Care
A child’s physical and mental development largely depends on parental care. Research by the National Institute of Child Health and Human Development (USA) shows that the attention and care of parents and caregivers affect a child’s holistic development, from physical to emotional and behavioral aspects.

Maternal Health and Newborns
Maternal health during pregnancy and breastfeeding directly impacts a child’s development, including height and weight. Stress during pregnancy can negatively affect a child’s mental health, cognitive abilities, and motor skills. The mother’s diet, especially adequate supplementation with iron, folic acid, calcium, and DHA, is crucial for the development of the child’s musculoskeletal system and immune resistance.
Sports Training for Height Increase
Active movement and sports training play an important role in height and weight development. A sedentary lifestyle and late nights affect the musculoskeletal and nervous systems, while also reducing sleep quality. Sleep and bone development are closely linked. Deep and sufficient sleep helps increase bone density, supporting height growth. Encourage children to participate in sports such as basketball, swimming, cycling, volleyball, jump rope, etc. Physical activity also helps overweight children reach an ideal weight and prevents diseases like diabetes and heart disease.
Frequently Asked Questions About Girls’ Height and Weight
The physical development of girls is always a primary concern for parents. Below are some frequently asked questions about children’s height and weight, along with useful information to help parents better understand children’s physical condition and how to care for their young children’s health.
What is the Height and Weight of a 15-Year-Old Child?
The height of a 15-year-old girl typically ranges from 152.9 cm to 166.5 cm, with an average of 159.7 cm (according to statistics with a standard deviation of +/- 6.8 cm). However, these are just reference figures. The actual height of each girl depends on many factors: genetics, nutrition for height development, the living environment affecting physical condition, chronic illnesses and physical development, as well as parental care. Factors influencing height include pediatric genetics, nutrition (folic acid, DHA, calcium, iron), sleep and bone development, sports training for height increase, and environmental factors. Research from reputable organizations such as the National Institute of Child Health (USA), the American Journal of Human Biology, and the United Nations University in Tokyo, Japan, has highlighted the importance of these factors.
How much should a 4-year-old girl weigh?
The ideal weight for a 4-year-old girl typically ranges from 15 kg to 16.1 kg, corresponding to an average height of 100 cm to 102.7 cm. Maintaining weight within this range is crucial for a child’s healthy and balanced development. Parents should regularly monitor their child’s development to ensure she is within the ideal height and weight range for her age.
Height and weight are important indicators reflecting physical development that parents need to monitor. By referring to the standard height and weight charts and implementing a reasonable diet and exercise regimen, parents can help their child achieve ideal height and weight. If you have any questions about childhood growth disorders or need advice on pediatric health and nutrition, please contact a doctor or nutritionist for support.
