What’s the average height for a girl?

Medical professionals use various bodily measurements, including height, to gain valuable insights into an individual’s health and well-being. Anthropometry, a scientific discipline, explores variables like body mass index, skinfold thickness, weight, and height to understand human physical characteristics. Additionally, researchers analyze average height trends across populations to uncover vital information about the health and quality of life in specific regions. This article delves into the average height of women worldwide, shedding light on the numerous factors influencing their stature.

The Stagnant Growth of Average Height in the United States

Over the last two decades, the average height of American girls has seen minimal change. As of 2016, the typical American woman stands just under 5 feet 4 inches tall, with an average weight of 170.6 pounds. Interestingly, it appears that weight is increasing at a faster rate than height.

Research has revealed correlations between nutrition during infancy, childhood, and adolescence and the potential for greater height. Additionally, there is a connection between a population’s standard of living and its average height. But what lies behind the slow growth of average height among Americans?

Some argue that limited access to quality nutrition is a contributing factor, while others suggest that dietary choices, lacking essential nutrients, may be to blame. Some even attribute the stagnation in height to immigration from countries with shorter average stature. However, which of these hypotheses is accurate? What truly determines an individual’s or a population’s height growth? Join us on this exploration to uncover the intricate factors influencing height evolution in the United States.

What Determines Height?

Genes or DNA primarily determine an individual’s final adult height, with nearly 700 genes contributing to this outcome. However, genetics alone do not dictate height entirely. Environmental factors, including nutrition, sleep, exercise, and living conditions, also play significant roles in height growth. Inadequate nutrition, poor sleep, lack of physical activity, and an unhealthy living environment can hinder growth. Illness during childhood and poor nutrition, closely tied to living standards, can lead to stunted growth in populations. Thus, a country’s average height reflects its overall quality of life.

Average Height for Women Around the World

Determining the global average height for women is challenging due to various sampling methods, statistics, and reports used by different countries. Moreover, India and China’s large populations significantly influence global averages. While the United States has seen slowed growth rates, other parts of the world have not experienced such trends.

For instance, South Korea has witnessed significant height increases, with women gaining nearly eight inches on average. In contrast, the Polynesian island nation of Tuvalu has experienced minimal height growth, gaining less than an inch.

The tallest and shortest women in the world differ by approximately eight inches in height. Guatemala boasts the shortest average height for women at just under 4 feet 10 inches, followed closely by Bangladesh, the Philippines, and Nepal, where women’s heights average around 59.4 inches. In contrast, Latvia, Estonia, the Netherlands, and the Czech Republic have the tallest women, with an average height reaching 5 feet 6 inches, or 66 inches.

Average heights also vary within regions. South Asian countries, such as Bangladesh and Nepal, have among the shortest women, while Central Asian (Uzbekistan and Iran) and European women rank among the tallest globally.

Understanding the Average Height of a Girl by Age

The average height of girls changes as they age, reflecting their growth and development. The following table from a CDC chart in 2000 provides a median height for girls by age:

Age (years) The median height (inches and centimeters)
0 21 in. (53.7 cm)
1 29 in. (74 cm)
2 33.5 in. (85 cm)
3 37.1 in. (94 cm)
4 40 in. (101.6 cm)
5 42.5 in. (107.9 cm)
6 45.5 in. (115.5 cm)
7 47.7 in. (121.1 cm)
8 50.5 in. (128.2 cm)
9 52.5 in. (133.3 cm)
10 54.3 in. (138 cm)
11 56.7 in. (144 cm)
12 59.4 in. (151 cm)
13 61.8 in. (157 cm)
14 63.2 in. (160.5 cm)
15 63.8 in (162 cm)
16 64 in. (162.5 cm)
17 64 in. (163 cm)
18 64 in. (163 cm)

How to Promote Height Growth in Girls

In addition to genetics, several factors contribute to a girl’s height potential. Here are ways to optimize height growth:

  1. Get Enough Sleep: Adequate sleep, around 8 to 11 hours for teenagers, allows for the release of the human growth hormone, supporting growth.
  2. Eat Nutritious Food: A diet rich in calcium, protein, healthy fats, iron, and vitamin D maximizes growth potential. Nutritious foods promote healthy growth.
  3. Stay Active: Regular exercise can enhance height growth, as physical activity stimulates the release of growth hormones. Activities like jumping, stretching, and dancing are beneficial.
  4. Maintain Good Posture: Practicing good posture can create the illusion of increased height. Keeping shoulders back, head level, and feet shoulder-width apart helps maintain proper posture.
  5. Dress Wisely: Clothing choices can affect how tall you appear. Darker shades, vertical stripes, and clothing that shows off legs can create the illusion of height. High heels or platform shoes can add temporary height.
  6. Take Height-Increasing Supplements: Consult with a doctor for suitable supplements that provide essential nutrients like vitamin A, vitamin D, calcium, and potassium. Supplements should only be taken during growing years.


The average height for women varies worldwide, influenced by genetics, nutrition, environment, and living standards. Understanding these factors is essential for monitoring an individual’s growth and health. While genetics play a significant role, optimizing nutrition, sleep, exercise, and living conditions can promote healthy height growth. The average height for girls at different ages provides a reference for tracking development. Ultimately, height should be viewed as a reflection of overall well-being rather than a measure of an individual’s worth.
