What is the Average Height for a 14 Year Old Boy and Girl? (Age 1-10, 11, 12, 13, 14, 15 Height and Weight)

What is the Average Height and Weight for a Boy and Girl According to Age?

When do boys and girls stop growing, what is the average height and weight for your child’s age, and how tall will your child likely be? Get the answers here.

Growth isn’t just about getting taller or heavier—it’s about how your body develops over time. A child’s brain grows fast in the first five years, reaching 90% of its adult size. Different body parts grow at different rates too; for example, the head is nearly fully grown by age 1. As kids grow, their bodies become more balanced, and by around 16-18 years old, most of their growth is done as their bones stop growing.

Doctors use growth charts to check if a child is growing normally. Here’s a look at average height and weight ranges of children in the US, based on data from the CDC.gov in inches (You can see the numbers in centimeters and kilogram below that chart):

When Do Boys Stop Growing?

Boys typically stop growing between the ages of 16 and 18, although growth can continue slightly into their early 20s in some cases. During puberty, which usually starts between the ages of 12 and 14, boys experience rapid growth spurts. These growth spurts are typically more intense and occur later than in girls. By around 18 years old, most boys will have reached their final adult height as the growth plates in their bones close. However, other factors like genetics, nutrition, and overall health can slightly influence when a boy stops growing.

When Do Girls Stop Growing?

Girls usually stop growing earlier than boys, typically around the age of 16. Most girls experience the majority of their growth during puberty, which generally begins between the ages of 10 and 12. Girls tend to reach their final height by the age of 16, or even earlier, as their growth plates in the bones close after their first menstrual period. Growth slows down significantly after this, with only minor increases in height occurring after the age of 14-16. Like boys, factors such as genetics and nutrition can affect the exact age at which growth stops.

This is the same chart as above but with inches and pounds on the Y-axis, instead of centimeters and kilogram.

Chart of Childrens’ Height According to Age – 5th, 50th and 95th Percentile.

On this chart, we have added the 5th and 95th percentile in boys’ and girls’ height for each age, to compare with the 50th percentile (median average).

How to read the chart:

• 5th Percentile: Boys in the 5th percentile are shorter than 95% of boys in their age group. Starting at around 73 cm at age 1, boys in this group steadily grow to about 171 cm by age 18. Their growth accelerates between ages 12 and 16, reflecting the typical onset of puberty.
• 50th Percentile: This represents the median or average height for boys. They start at about 76 cm at age 1 and grow to about 178 cm by age 18. Growth is relatively steady until puberty, with rapid height increases between ages 12 and 16. Growth slows considerably after age 16.
• 95th Percentile: Boys in the 95th percentile are taller than 95% of boys their age. These boys start at 80 cm at age 1 and reach about 185 cm by age 18. They experience the same rapid growth during puberty but begin from a higher base height.

Growth Spurts in Children.

Growth spurts are periods of rapid physical growth that occur in children, most notably during infancy and adolescence. During these phases, children can grow significantly in height over a short period of time. For girls, the biggest growth spurt typically occurs between ages 10 and 14, coinciding with the start of puberty. Boys tend to experience their growth spurt a bit later, usually between ages 12 and 16. Growth spurts are accompanied by an increase in appetite, changes in sleep patterns, and sometimes mood swings, as the body adapts to its rapid development.

How to Increase Height in Children with Nutrition.

While genetics play a significant role in determining height, proper nutrition is essential for ensuring that a child reaches their full growth potential. Nutrient-rich diets that are high in protein, calcium, vitamin D, and other essential vitamins and minerals can support healthy bone development and growth. Foods such as dairy products, lean meats, fish, eggs, fruits, and vegetables are important for supplying the body with the necessary nutrients for growth. Staying hydrated and maintaining a balanced diet can also help maximize a child’s height during their growth years. Additionally, adequate sleep and regular physical activity are crucial for overall growth.

How to Increase Height with Medicine.

There are no medicines that can significantly increase height once the growth plates in bones have closed, which typically happens by the end of puberty. However, in rare cases where a child is significantly shorter than expected due to a growth hormone deficiency, a doctor may prescribe growth hormone therapy. This treatment is only used for specific medical conditions and must be carefully monitored by a physician. It involves administering synthetic growth hormones to stimulate growth in children whose growth is delayed or stunted due to hormonal issues. It’s important to note that growth hormone therapy is not effective for children who do not have a hormone deficiency, and there are risks involved with its use.

Height Differences Based on Race and Ethnicity

Height can vary significantly depending on racial and ethnic backgrounds due to genetic and environmental factors. Here are some general observations:

• Caucasian (European/American) Children: Caucasian children in the U.S. and Europe tend to have slightly higher average heights compared to other ethnic groups. For example, boys and girls in Western countries like the U.S. and the Netherlands are generally taller than the global average.
• Asian Children: Children from East Asian countries such as Japan, China, and South Korea are typically shorter on average compared to their Western counterparts, although there has been a significant increase in height in recent decades due to improved nutrition and health standards. Southeast Asian children from countries like Indonesia, the Philippines, and Thailand tend to be on the shorter side as well.
• African and African American Children: Children of African descent often show higher rates of growth during their growth spurts. African American children, in particular, may experience earlier growth spurts compared to their Caucasian peers, leading to early height gains.
• Latino Children: Children from Latin American countries like Mexico, Brazil, and Argentina often have heights that vary by region and country. Factors such as nutrition, economic conditions, and health care access play a significant role. In some countries, children are slightly shorter than in Western Europe or North America, but this is changing with better living standards.
• Children from Nordic and Northern European Countries: Countries such as the Netherlands, Denmark, and Norway have some of the tallest populations in the world. Dutch children, for example, are consistently among the tallest globally. Nutrition and genetics play a key role in these countries’ height averages.

Height Differences Based on Country (Adults).

Average height varies not only by race but also by country, as factors like diet, healthcare access, and lifestyle play critical roles in growth. Some countries have populations that are notably taller or shorter than the global average:

• Netherlands: Dutch people are among the tallest in the world, with Dutch men averaging around 6 feet (183 cm) tall. Dutch women are also tall, averaging about 5 feet 7 inches (170 cm). The tall height of the Dutch is often attributed to high standards of living, quality healthcare, and nutrition.
• United States: In the U.S., the average height for men is around 5 feet 9 inches (175 cm) and for women, about 5 feet 4 inches (162 cm). Height in the U.S. varies significantly across different ethnic groups and socioeconomic classes.
• Japan: Historically, Japan had shorter average heights compared to Western countries, but in recent decades, Japanese children have grown significantly taller due to improvements in nutrition and healthcare. The average height for Japanese men is now around 5 feet 7 inches (170 cm), while women average 5 feet 2 inches (158 cm).
• India: Indian children are typically shorter on average compared to Western counterparts. Factors such as malnutrition, healthcare access, and socioeconomic conditions have affected average height. Indian men average around 5 feet 5 inches (165 cm), and women average around 5 feet (152 cm).
• Brazil: In Brazil, height is influenced by the diversity of the population, with averages around 5 feet 8 inches (173 cm) for men and 5 feet 4 inches (162 cm) for women. Improvements in nutrition and healthcare have also led to a gradual increase in height.
• South Korea: South Korea has seen dramatic changes in average height over the past several decades. Improved healthcare and a focus on balanced diets have contributed to a significant increase in average height, with men averaging around 5 feet 9 inches (175 cm) and women 5 feet 4 inches (162 cm).

Environmental and Economic Factors Affecting Height in Children.

In addition to genetics and race, environmental factors such as nutrition, healthcare, and living standards also play crucial roles in determining a child’s height. Children growing up in countries with access to high-quality healthcare, well-balanced diets, and a healthy lifestyle are more likely to reach their full height potential. Conversely, in areas with high rates of malnutrition, poor healthcare, and challenging living conditions, children may experience stunted growth.

Growth spurts and average height in children are influenced by a combination of race, genetics, environmental factors, and geography. Countries with improved living standards, healthcare, and nutrition generally see taller populations, while other regions may have shorter average heights due to various socio-economic factors.

How Tall Will I Be?

Determining a child’s future height can be estimated using the heights of the mother and father. While genetics play the biggest role in predicting height, other factors such as nutrition, health, and environment also influence growth. There are some general methods that can give you an estimate of a child’s potential adult height.

Mid-Parental Height Formula:

One of the most common ways to estimate a child’s height is the mid-parental height formula, which takes into account the heights of both parents. Here’s how it works:

For Boys:

• Add the mother’s height and the father’s height (in inches or centimeters).
• Add 5 inches (13 cm) to the total.
• Divide the result by 2.

For Girls:

• Add the mother’s height and the father’s height (in inches or centimeters).
• Subtract 5 inches (13 cm) from the total.
• Divide the result by 2.

Example:

• Father’s height: 6 feet (72 inches / 183 cm)
• Mother’s height: 5 feet 5 inches (65 inches / 165 cm)

For a boy:

• (72 + 65 + 5) / 2 = 71 inches (or about 180 cm)

For a girl:

• (72 + 65 – 5) / 2 = 66 inches (or about 168 cm)

So, the boy is estimated to be 71 inches (180 cm) tall, while the girl is estimated to be 66 inches (168 cm) tall.

Genetic Height Range.

Genetics usually determine about 60-80% of a child’s height, meaning the mid-parental height estimate will often be close but not always exact. Children may end up taller or shorter than predicted based on the influence of other genetic factors from grandparents or extended family members.

Other Factors That Influence Height.

While the mid-parental formula gives a rough estimate, other factors can significantly impact a child’s growth:

• Nutrition: A well-balanced diet rich in proteins, calcium, and vitamins can support a child’s growth. Malnutrition, particularly during important growth periods like puberty, can stunt growth.
• Sleep: Growth hormones are primarily released during sleep, so children who get adequate rest tend to grow more consistently.
• Exercise: Physical activity, particularly weight-bearing exercises, supports bone development and healthy growth.
• Health Conditions: Chronic illnesses, hormonal imbalances, and conditions like growth hormone deficiency can affect height. If a child has these conditions, medical intervention might be necessary to support normal growth.

Growth Percentiles and Monitoring.

A child’s growth chart is typically monitored by pediatricians to ensure they are following a normal growth pattern. If a child’s height deviates significantly from the predicted range or the average growth chart, a healthcare provider might look into potential causes or offer suggestions for ensuring healthy growth.

While genetics play the largest role in determining a child’s height, environmental factors like nutrition and overall health are important in helping a child reach their full height potential. The mid-parental height formula provides a useful estimate, but it’s important to remember that this is only an approximation, and children can vary widely in their final adult height.
