What is the average weight and height of an 11-year-old child?

What is the average weight and height of an 11-year-old child? How can we determine if a child’s height and growth rate meet the standards at the age of 11? We can learn more through the following article from Debametulam.com.

The growth rate of an 11-year-old’s height is quite impressive if they have three factors in place, including nutrition, exercise, and adequate sleep. With these factors met, height can increase by 8-10 cm each year. However, only some children can achieve this growth rate due to the gaps in their parents’ health programs. Doctorplus.vn’s article below provides tips to help children successfully increase their height. However, first, we need to determine the normal weight and height for an 11-year-old child.

What is the standard height for an 11-year-old child?

If an 11-year-old child meets the following height and weight standards, then they are considered acceptable.

  • Boys: 143.5 cm – 35.6 kg
  • Girls: 144.0 cm – 36.9 kg

The height and weight standards do not stop there; they will continue to develop in the coming years. If the nutritional requirements for eating, exercise, and sleep are scientifically met, these two indicators will change significantly and be compatible with each other to achieve a balanced body.

If your child is “almost there” with the standard numbers, parents need to develop a growth plan for their child to benefit from their potential growth during puberty. To achieve this, parents need to have basic knowledge about the time frame for height growth during puberty.


The important stages that affect height

During the development and growth of the body, the height of the body is divided into three main stages including the fetal stage, the first three years, and the puberty stage.

Fetal stage

The fetal stage is the stage where the height development of the baby depends on the nutrients from the mother’s body. If the mother has an active and healthy lifestyle, fulfills all requirements for a complete diet, adequate rest, good physical and mental health, then the baby will definitely reach maximum height (about 50 cm). On the contrary, the baby may be stunted or underweight, affecting the baby’s development.

The first three years of life

The first three years of life are one of the two most genetically developmental periods for a child. Adequate breastfeeding and nutrition during this time create conditions for the child to reach their highest weight and height potential.

Important milestones in a child’s weight and height development during the first three years should not be overlooked:

  • At one year old, the child is approximately 25cm taller and gains around 2.2kg in weight.
  • At two years old, the child grows 11-13cm taller and gains around 2.2kg in weight. The average height of a two-year-old girl is 85cm, and the average height of a two-year-old boy is 88cm.
  • At three years old, the child grows 5-6.2cm taller and gains an additional 2kg in weight.

From age three to puberty, the child’s weight and height development rate will not be significantly affected. This is also the best time for parents to establish healthy habits for their children to build a foundation for their overall physical and mental development.

The puberty stage

The puberty stage is the second stage where the body begins to develop strong genetic abilities and is in a position to overcome weaknesses from the previous stage. This is also the final stage to increase height for children, but if not carefully taken care of, not every method can help children grow taller.

The puberty stage is divided into 3 main stages corresponding to the speed of height growth:

  • The beginning of the stage
  • The period of accelerated growth (AGS)
  • End of the period

The AGS stage is the stage where the weight and height of children grow the most. The average height for boys increases about 10.3cm per year, while the average height for girls increases 9cm per year.

If children do not enter puberty early or late, the AGS stage begins at age 11 and reaches its peak at age 13 for boys. For girls, the peak of AGS will begin around age 9 and reach the highest point around age 11.

At age 11, if it’s a boy, this is the beginning of the AGS stage. If it’s a girl, it’s her peak. Therefore, building an appropriate height growth strategy for children to maximize their potential during puberty is extremely necessary.


An effective method to increase height for 11-year-old children

To ensure fast development in children, parents should prepare a plan that is suitable for their age. Below are three effective ways to increase height for 11-year-old children that parents can refer to.

Recording Growth Phases

Knowing the growth pattern of the entire population is crucial to ensuring that children have the physical support they need to develop. To achieve this, parents should:

  • Draw up a growth chart to monitor their child’s development
  • Schedule regular health check-ups

Creating a growth chart will help parents determine if their child’s height and growth rate are meeting the standards. Regular check-ups with a doctor will also help to monitor the child’s health status and enable parents to develop an appropriate plan for height growth during the child’s growth phases.

Developing a strategy to increase children’s height

To ensure that the strategy to increase children’s height is effective, it must be age-appropriate and fulfill three important nutrition factors including exercise and rest.

Ensure that your child’s diet provides enough energy

Nutrition is 3/4 of the important factors for height. To help children grow quickly, parents must provide adequate nutrition for their children through daily breakfast.

A typical meal that provides enough “ingredients” for bone lengthening should include protein, fat, sugar, starch, vitamins, and minerals. These nutrients are all abundant in natural foods. Note how to shop, select, prepare and preserve food to maintain the high nutrient content.

If your child is affected by the “passion” for carbonated drinks, soda, fast food, you can gradually reduce this behavior to avoid affecting the overall development of the body.

Encourage physical activity

20% of the chance of achieving normal height depends on a child’s body movements. Just 30 to 45 minutes of activity per day will allow children to increase their joint flexibility and strength. Additionally, this is an effective method to stimulate the body to produce growth hormones, which help increase height.

Guide children to choose activities or sports that significantly impact height, such as badminton, swimming, volleyball, yoga, etc. Furthermore, encouraging children to participate in school sports clubs will also provide the best conditions for them to have the opportunity to exercise their health throughout the day.

Your child should be taught about the importance of sleep.

Sleep is the main factor contributing to 25% of the height increase process and all height-increasing activities are performed during sleep. However, many parents do not realize the importance of this aspect. This is one of the reasons why a child may have difficulty growing up even though other aspects have been met. In addition, 8-9 hours and 10 pm are significant numbers that help children achieve normal height in the near future.

10 pm: The body enters deep sleep within an hour of falling asleep. 11 pm and 1 am are also the times when growth hormone reaches its peak.

8 to 9 hours: Each organ in our body will have its own framework to perform detoxification and ensure that the body is healthy enough to carry out activities that improve height.

Using growth-supporting products is one of the methods to help you enhance the absorption of nutrients, especially calcium – the most important nutrient necessary for bone structure. Some growth-supporting products also contain ingredients such as vitamin D, collagen, vitamin K, and amino acids, which may be beneficial for bone development.

To ensure that the child benefits from the products they use, parents must choose products that are appropriate for the child’s age and have the best nutritional ingredients, while buying products from a reputable company to ensure safety for the child. The health and happiness of children are the most important things.

Caring for the mental well-being of children

Changes in the psychological state of children at the age of 11 need to be particularly concerned by parents. A strong mental foundation will help children have the opportunity to develop physically, intellectually, and in height.

Parents can refer to the following advice to make it easier to “befriend” their children during this difficult time.


  • Share positive energy.
  • Help children understand healthy relationships.
  • Assist children in making their own choices.
  • However, it is still important to protect children’s privacy.
  • Educate children about sex.
  • Regular family activities take place.

At the age of 11, children are going through a significant stage of development. Parents must create the best possible conditions for their children to benefit the most during this puberty period. In addition to understanding the developmental situation and taking care of mental development, planning for height development through a proper diet, regular exercise, and sufficient sleep are important factors that parents should not overlook.
