This free height percentile calculator allows you to calculate how tall am I?, or determine whether your child's growth is on track. You can compute your child's height percentile, compare it with normal growth standards, and estimate the expected height for boys or girls using this online growth percentage calculator. Below, we explain every aspect of the height percentile calculator.

What is Height Percentile?

Height percentile measures how your height compares to others in the same age and gender group.

In simple terms, if you are in the 75th percentile for height, you are taller than 75% of people your age. Height percentiles are primarily based on CDC data in the United States, and they are commonly used for children and teens to track growth trends.

Median and Average Height for Men and Women

Height generally follows a normal distribution, with most people clustering around the average. The average and median heights for men and women are usually very similar.

Average and Median Height for Women

According to the Centers for Disease Control and Prevention (CDC), the average adult female height in the U.S. is approximately 5 feet 4 inches. A teenage girl can use this data to calculate her height percentile using an online height percentile calculator for girls.

Average and Median Height for Men

The age-adjusted average height for American men aged 20 years and older is about 5 feet 9 inches. Teenage boys can use a height percentile calculator for boys to compare their growth with these averages.

Average Height Data Sources

Height percentiles for children and infants are typically based on the World Health Organization (WHO) growth charts for newborns and children up to 24 months. For children older than 23 months and teenagers, the CDC Growth Charts, which are based on the U.S. NHANES population survey, are used. This means the United States is the default option in many percentile calculators.

For adults, data comes from national surveys of various countries, including the U.S., Canada, Mexico, most European countries, and others. Since genetic and environmental factors affect height, it is important to compare your height with the correct country-specific averages.

Height percentiles are calculated using worldwide average heights and standard deviations, as summarized in studies such as Jelenkovic et al., focusing on individuals born between 1980 and 1994. Note that sample biases and self-reported measurements may introduce minor inaccuracies.

This free height percentile calculator helps you determine how tall am I?, assess whether your child's growth is on track, and calculate height percentiles for boys or girls. You can also see what the expected height should be for normal growth. Below, we explain each aspect of the height percentile calculator.

Other Types of Percentiles

Besides height percentiles, there are many other types of percentiles used in statistics to determine the relative position of a number within a dataset. For such calculations, you can use a percentile calculator that performs these computations in seconds.

How to Calculate Age-Based Height Percentile

Tracking a child’s height percentile by age is a reliable way to monitor their growth. Boys and girls mature at different rates due to varying hormone levels and body structures. Here's how to calculate it:

Height changes with age and gender because of body structure and hormonal fluctuations during growth.
Children do not grow at a constant rate; there are periods of slower growth and sudden growth spurts.
Growth charts are designed to compare a child’s height with others of the same age and gender.
Height distribution charts are based on standardized data collected from thousands of children.
To find a child’s percentile: locate their age on the X-axis, height on the Y-axis, and see where it intersects the curve to determine the percentile.

You can also use an online growth percentile calculator to simplify this process. Once you know your child’s height percentile, you may also track weight growth using a baby weight percentile calculator.

Height Percentile Chart

Men typically grow taller than women. The table below shows height percentiles for U.S. adults and teenagers, verified by a height chart calculator:

Percentile	Male Height	Female Height
1%	5'1.54"	4'8.85"
10%	5'5.2"	5'0.04"
25%	5'7.01"	5'1.65"
50%	5'9.17"	5'3.58"
75%	5'11.02"	5'5.63"
90%	6'0.64"	5'6.97"
99%	6'3.57"	5'9.72"

The calculator can display results in feet/inches, meters, or centimeters.

Important Facts About Height Percentiles

When reviewing height charts, doctors consider the following growth patterns:

It is important that a child follows a consistent percentile line as they grow.
If results shift dramatically between percentile lines (e.g., from 75th–85th to 15th–25th percentile), consult a doctor.
If a child’s height moves outside the typical 3rd–97th percentile range, check whether this has been consistent. Sudden changes may require medical attention.

FAQs

What percentile is my height?

You can quickly calculate your height percentile using our online height-for-age calculator. This will tell you how your height compares with others of the same age and gender.

How does my height compare to others?

By comparing your height to the average in a specific country (like the United States), the calculator can show what percentage of the population you are taller than or shorter than.

Who is the tallest man?

The tallest living man is Sultan Kösen from Turkey, standing at 251 cm (8 ft 3 in). Historically, Robert Pershing Wadlow (1918–1940) was the tallest man ever recorded, at 272 cm (8 ft 11 in).

The tallest woman recorded in medical history was Zeng Jinlian from Hunan, China, who reached 248 cm (8 ft 1.5 in) and passed away at age 17.

What percentile is considered healthy for toddlers?

There is no single “ideal” percentile for toddlers. Healthy children can fall anywhere on the growth chart. For example, a baby in the 5th percentile can be just as healthy as one in the 95th percentile.

How often should my baby be weighed or measured?

General guidelines for tracking your child’s growth are as follows:

2 weeks to 6 months: measure once a month
6 months to 12 months: measure once every 2 months
12 months to 2 years: measure once every 3 months
2 years to 4 years: measure once every 6 months
5 years and older: measure once per year

Conclusion

Height percentiles are a useful way to determine whether a child or adult is unusually short or tall. They can also help identify potential growth-related issues. Endocrinologists, pediatricians, and genetic specialists can provide further guidance if needed. Using this online height percentile calculator, you can quickly determine the percentile for males and females, providing valuable insight into growth trends and patterns.
