Height Percentile Calculator

Use this height percentile calculator to calculate how tall or short you are relative to the general population or to people of the same gender, age, and country you are in. Child height percentiles are only available for U.S. citizens (based on CDC data). Newborns, toddlers and infants data is based off WHO's Child Growth Standards. The calculator supports feet and inches, as well as meters and centimeters.

Using the height percentile calculator

With the help of our height percentile calculator you can calculate what percentile of the population your height falls in, what percentage of people of the same gender, age & country are shorter or taller than you. The calculator can also be used for infants, toddlers and children, including newborn babies. The results from the calculator do not constitute health advice. Always consult a certified physician before taking any action related to your health or the health of your children.

To use the tool, first, select a biological sex (gender), then enter the current age of the person: type in whole years manually and select the number of months by rounding to the nearest whole month. For a newborn, enter zeroes in both years and months. Enter the person's height in feet and inches or in cm or meters. If doing this for your child or toddler, enter their age and height. Then select the country with whose population you want to compare the height. For adult men and women this should be the country they have spent most of their child and teenage years in, if you want a fair comparison. Finally, press "Calculate Height Percentile" to see which percentile the person falls in.

Data for infants and children up to 24 months is based on the World Health Organization Child Growth Standards[1]. Data for children older than 23 months and teenagers is from the United States NHANES population survey[2] used to compile the CDC Growth Charts and thus "United States" is the only option available in the country selector if you input an age in this range. Adult height data is from various sources, mostly national surveys of the respective countries: currently 116 of them, including the U.S., Canada, Mexico, most European countries, and others. Comparing your height to the correct country average is important since average height varies considerably between countries due to genetic and environmental factors.

How we calculate the height percentile

The assumption behind the calculator is that height in human populations follows an approximately normal distribution. Knowing the mean and standard deviation of a normal distribution means one can compute the cumulative distribution function and thus see where a particular measurement falls in terms of cutting out a certain percentage of the total distribution. Since standard deviation data is not available for all listed countries, we use estimates from neighboring countries. For other countries height data is only available for one gender - in such cases we estimated the height of the other using the average difference in the mean height of human males and females.

It should be noted that the further away from the population mean a given stature is, the larger the probability of an error due to sampling error in surveys.

Average height of United States citizens

Below we present average heights for males and females in different ages based on the US CDC growth charts with data gathered as a part of the U.S. NCHS National Health and Nutrition Examination Survey (2011-2014) [2].

Above is the average (mean) height comparison for U.S. citizens aged 0+, while below is the median height of U.S. citizens aged 0-20, again by gender (men, women).

As you can see, there is a clear trend for height to increase for both young boys and girls till about adulthood and then decrease slightly for both genders in the late adult years. Due to this later decrease we adjust the mean estimates slightly if your age is in the 70-79 or 80+ range. On the other hand, due to the rapid growth of baby boys and baby girls, as well as toddlers, we have more refined data for each month so that a more accurate percentile can be calculated.

Who is the tallest man?

According to Wikipedia the tallest living man is Sultan Kösen of Turkey with a stature of 251 cm (8 ft 3 in). In modern history, the tallest man was Robert Pershing Wadlow (1918–1940), from Illinois, US, who was 272 cm (8 ft 11 in) when he passed away.

Going further back the tallest woman in medical history appears to be Zeng Jinlian of Hunan, China, who stood at 248 cm (8 ft 1 1⁄2 in) when she died at the age of 17.

On the opposite side we have the shortest adult human on record: Chandra Bahadur Dangi of Nepal with a height of only 54.6 cm (1 ft 9 1⁄2 in).
