The Average Height For 8-year-old

Measuring a child's height has long been a common practice to assess their general health and development. As caregivers, we constantly keep an eye on our children's growth, often pondering whether they are progressing as expected for their age. If you find yourself curious about what constitutes an average height for 8-year-olds, you've come to the right place. Join us as we explore this topic in the following discussion

How tall should an 8-year-old be?

According to the World Health Organization (WHO), the average height for an 8-year-old boy is around 4 feet 2 inches (128 centimeters), while for an 8-year-old girl, it is about 4 feet 1 inch (126 centimeters) [1, 2].

But note that these are just average heights for youngsters of this age. Some may be taller or shorter, and this is perfectly normal.


What factors affect height growth?

Genetics plays a significant role in determining a person’s height. If parents are tall, their kid is more likely to be tall. Also, nutrition, exercise, and sleep can affect height growth. Children who have a balanced and nutritious diet and engage in physical activities regularly might grow taller than those who do not. Moreover, getting enough sleep is essential for growth as the body produces growth hormones.

Is there anything else?

Hormones play an important role in growth and height. Hormones, like growth hormones, thyroid hormones, IGF-1, and sex hormones, are chemical messengers produced by glands in the body and transported through the bloodstream to target organs and tissues, where they stimulate various processes, including growth and development.

Some medical conditions might bring negative effects on height increase. For example, conditions that affect the thyroid gland, such as hypothyroidism, can lead to stunted growth. Turner syndrome and achondroplasia may also result in short stature.

What tips help 8-year-olds grow?


Ensure proper nutrition

Aside from genetics, nutrition is one of the most critical factors affecting height. Children who have a balanced diet that includes adequate amounts of protein, vitamins, and minerals are more likely to grow taller than those who do not.

  • Lean meat is an excellent source of protein since it provides the building blocks for the body to grow and develop. Add chicken, turkey, fish, and lean cuts of beef and pork into every meal to give your children enough protein as well as other essential nutrients, like iron and zinc, which are important for healthy blood and immune function.

  • Dairy products, such as milk, cheese, and yogurt, are rich in calcium and vitamin D essential for bone growth and development. Low-fat or fat-free dairy products are a good choice to limit excess fat intake.

  • Whole grains contain a high amount of fiber, vitamins, and minerals, which might promote healthy digestion and regular bowel movements. Whole wheat bread, brown rice, oatmeal, quinoa, and barley are good sources of whole grains you should not miss.

  • Fruits and vegetables are packed with essential nutrients and antioxidants for boosting immunity and supporting overall health. Encourage your children to eat a variety of colorful fruits and vegetables, including leafy greens, berries, citrus fruits, apples, carrots, broccoli, and sweet potatoes.

  • Nuts and seeds, such as almonds, walnuts, sunflower seeds, and chia seeds, include healthy fats, protein, and fiber. They can be added to meals or eaten as a snack, providing a nutritious boost to the diet.

  • Legumes are low in fat and calories and can be a healthy and filling addition to meals thanks to their great amount of protein, fiber, minerals, and vitamins. You easily find them in beans, lentils, and chickpeas.

Encourage regular physical activities

Exercise not only promotes healthy growth and development but also helps children maintain a healthy weight, strengthen their muscles and bones, and boost their mood and cognitive function. Check out some options that are suitable for 8-year-olds.

  • Running and jogging are excellent forms of cardiovascular exercises for building endurance and stamina. Encourage your children to run or jog around the block or in a local park for at least 20-30 minutes each day.

  • Jumping rope for 5 to 10 minutes at a time is helpful in improving coordination, balance, and agility.

  • Swimming is a low-impact exercise that your kids should join to strengthen their cardiovascular health, build strength and endurance, and boost their coordination and balance.

  • Cycling is also great for building leg muscles. Let your child ride their bike around the neighborhood or on local bike trails regularly.

  • Team sports, like soccer, basketball, and baseball, allow your children to develop their social skills, teamwork, and coordination while also getting active.

Get enough sleep


Sleep is essential for the overall health and well-being of 8-year-olds. During sleep, their body produces necessary growth hormones for supporting healthy growth. Children who get enough sleep are also better able to focus and concentrate, learn new information, and retain it over time.

Based on the National Sleep Foundation guidelines, kids at this age need between 9 and 11 hours of sleep each night [3]. But some may need more or less sleep to function at their best.

Get sunlight exposure

Embracing the natural gift of sunlight can be a transformative factor in nurturing a healthier and more vibrant life. Sunlight, beyond its luminous beauty, harbors an incredible treasure trove of benefits for the human body. Among its many virtues, it serves as an abundant source of vitamin D, a vital element that facilitates the efficient absorption of calcium, pivotal in the formation and maintenance of robust bones. Furthermore, it plays a pivotal role in regulating the production of growth hormones, an indispensable component of normal growth and development.

For our little ones, the effects of sunlight are even more profound. Children basking in its gentle embrace tend to display increased enthusiasm for physical activity and a sunnier disposition, fostering an environment conducive to their wholesome growth and development.

Nonetheless, it is crucial to strike a harmonious balance in sun exposure, as excessive amounts can lead to adverse health consequences, notably an elevated risk of skin damage and the dreaded specter of skin cancer. Thus, it is judicious to encourage outdoor activities during daylight hours, with a particular emphasis on the early morning or late afternoon when the sun's radiance is less intense. In addition, safeguarding your children's delicate skin with sunscreen boasting a high Sun Protection Factor (SPF) is paramount in ensuring their well-being amidst the sun's nurturing embrace.

Consider dietary supplements

If your precious little ones are fortunate enough to enjoy a diet that's rich in all the necessary nutrients, then the need for supplements is rendered obsolete. However, in cases where certain munchkins possess unique nutritional requirements, their trusted healthcare provider might come to the rescue with tailored recommendations for vitamin or mineral supplements. Consider, for instance, the scenario of children who shun dairy delights – they might find solace in a calcium supplement, a veritable elixir of bone health, ensuring their tender frames receive the nourishment they deserve.

Final word

It is essential to grasp the concept of average height as a vital metric for tracking your children's growth patterns. Furthermore, it's crucial not to overlook the valuable advice provided earlier, which can play a significant role in enabling them to reach their full potential in terms of height and lead a vibrant, healthy life in the years to come.
