This height percentile calculator shows what percentile your height falls into by comparing it to the adult population using a normal distribution. Enter your height in feet and inches (or switch to centimeters), pick your sex and population, and you get an instant answer. For example, a US man who is 5 ft 10 in (177.8 cm) lands around the 63rd percentile, meaning he is taller than roughly 63 percent of US men. A US woman at 5 ft 4 in (162.6 cm) lands around the 55th percentile. The result also shows your z-score, the number of standard deviations you sit from the average, which is the actual statistic behind every percentile.
What is the Height Percentile Calculator?
Adult height follows a bell curve very closely, which is exactly why a height percentile calculator can be both simple and accurate. Within one sex and one country, most people cluster near an average, and the number of people gets smaller as you move toward the very short or very tall extremes. Two numbers describe that curve: the mean (the center) and the standard deviation (how spread out heights are). Once you know those, you can place any height on the curve and read off its percentile.
The percentile is just the share of the population you are taller than. If your height sits at the 63rd percentile, you are taller than about 63 percent of adults in that group and shorter than the other 37 percent. The 50th percentile is the median, which for a symmetric bell curve is also the average height. This is why answering what percentile is my height is more useful than comparing yourself to a single average number: the percentile tells you how you rank, not just whether you are above or below the middle. It also explains why a common question like is 5 ft 9 in tall for a man does not have a single yes or no answer. Against the US male average of 175.4 cm, 5 ft 9 in (175.3 cm) is almost exactly the 50th percentile, right in the middle, not tall and not short.
Behind the scenes the tool converts your height to a z-score, which measures how many standard deviations you are from the mean. A z-score of 0 is exactly average (the 50th percentile). A positive z-score means above average, a negative one means below average. Because roughly 68 percent of people fall within one standard deviation of the mean and about 95 percent within two, a z-score also tells you how unusual a height is: a z of +2 is taller than about 98 percent of the group, while a z of -2 is shorter than about 98 percent of it.
The averages matter because height varies a lot between populations, so height percentile by country is not a gimmick. US men average about 175.4 cm while the global male average is closer to 171 cm, so the same height ranks differently depending on which group you compare against. Dutch men, for comparison, average around 183.8 cm, the tallest national average recorded anywhere, while the shortest national male average sits around 158 cm in parts of Southeast Asia. That is why this calculator lets you choose United States or a global average, and separates male height percentile from female height percentile: mixing sexes or countries would give a misleading rank.
Height itself is driven mostly by genetics, with an estimated 80 percent of the variation between individuals coming from inherited factors, but nutrition, childhood health, and living standards shift the population average over time. That is called the secular trend in height: average heights in most countries rose noticeably across the 20th century as nutrition and healthcare improved, and in a few high-income countries the trend has since leveled off. It is one reason percentile figures are periodically re-based on newer survey data rather than fixed forever.
A few honest limits are worth stating. Real height data is not a perfect bell curve, it can be slightly skewed and it shifts over generations, so treat the percentile as a close estimate rather than an exact census figure. The figures here are adult values drawn from national survey data such as CDC NHANES, so they do not apply to children or teenagers, whose height must be read against age and sex specific growth charts. Used within those limits, though, the calculator gives a reliable, research grounded answer to how tall am I compared to others.
When to use it
- Answering the everyday question of what percentile is my height without hunting through survey PDFs.
- Comparing the same height against different groups using height percentile by country, for example US versus the global average.
- Checking a male height percentile or female height percentile separately, since the two distributions are quite different.
- Understanding your height z-score so you can see how many standard deviations from average you are.
- Settling friendly debates about who is tall or short within a specific population rather than a vague worldwide guess.
- Getting a quick sense of how tall you are compared to others before buying clothing, sports gear, or ergonomic equipment sized by height.
- Checking where a specific height, such as 5 ft 9 in or 6 ft, actually falls before assuming it counts as short or tall.
How to use the Height Percentile Calculator

Formula & method
Worked examples
A US man who is 5 ft 10 in tall wants his height percentile.
- Convert height to cm: (5 x 12 + 10) x 2.54 = 177.8 cm
- US male mean = 175.4 cm, SD = 7.4 cm
- z = (177.8 - 175.4) / 7.4 = 0.32
- percentile = CDF(0.32) x 100 = 62.7, which rounds to 63
Result: 63rd percentile: taller than about 63% of US men.
A US woman who is 5 ft 4 in tall checks her female height percentile.
- Convert height to cm: (5 x 12 + 4) x 2.54 = 162.6 cm
- US female mean = 161.7 cm, SD = 7.1 cm
- z = (162.6 - 161.7) / 7.1 = 0.13
- percentile = CDF(0.13) x 100 = 55.0, which rounds to 55
Result: 55th percentile: taller than about 55% of US women.
A man who is 6 ft 0 in tall compares against the global male average.
- Convert height to cm: (6 x 12) x 2.54 = 182.9 cm
- Global male mean = 171 cm, SD = 7.1 cm
- z = (182.9 - 171) / 7.1 = 1.68
- percentile = CDF(1.68) x 100 = 95.3, which rounds to 95
Result: 95th percentile worldwide: taller than about 95% of men globally.

Common mistakes to avoid
- Comparing against the wrong population. A height that is average in one country can be tall or short in another. Using height percentile by country matters: pick United States or the global average deliberately, because the same number gives different results against different means.
- Mixing male and female distributions. Men and women have different average heights and spreads, so a male height percentile and a female height percentile are not interchangeable. Always select the correct sex, or the rank will be off by a large margin.
- Using it for children or teenagers. These are adult figures. A growing child must be assessed on an age and sex specific pediatric growth chart, where percentiles are read against age. This tool would badly misrepresent a child.
- Treating the percentile as an exact census figure. Real height data is only approximately a bell curve and shifts over time as nutrition and living standards change, so the percentile is a close statistical estimate, not a precise count of every person alive today.
- Confusing percentile with percentage taller. Being in the 63rd percentile means you are taller than 63% of the group, not that you are 63% as tall as someone. The percentile is a rank, not a ratio of heights.
- Entering height in the wrong unit. Typing a centimeter value into the inches field, or vice versa, produces a wild z-score. Double check that the unit toggle matches the number you are entering.
Glossary
- Percentile
- The share of a population you rank above. The 63rd percentile means you are taller than about 63 percent of the group.
- Z-score
- How many standard deviations your height is from the mean. Zero is average, positive is above average, negative is below.
- Mean
- The average height of the chosen group, which for a symmetric bell curve is also the 50th percentile.
- Standard deviation (SD)
- A measure of how spread out heights are. Larger SD means more variation between the shortest and tallest people.
- Normal distribution
- The bell shaped curve that adult height follows closely, symmetric around the mean.
- CDF (cumulative distribution function)
- The function that turns a z-score into a percentile by giving the fraction of the curve below that point.
- Error function (erf)
- A mathematical function used to compute the normal CDF. This tool approximates it with Abramowitz and Stegun formula 7.1.26.
- Median
- The middle value, the 50th percentile. Half the population is taller and half is shorter.
- Secular trend in height
- The gradual rise in average population height across generations as nutrition, healthcare, and living standards improve, which is why height surveys are periodically updated.
Frequently asked questions
What percentile is my height?
Enter your height, sex, and population above and the height percentile calculator shows it instantly. The percentile is the percentage of that group you are taller than, computed from a normal distribution of adult heights.
What height percentile is 6 feet tall?
For US men (mean 175.4 cm, SD 7.4 cm), 6 ft 0 in (182.9 cm) is about the 84th percentile. Against the global male average it rises to roughly the 95th percentile, which shows why height percentile by country matters.
Is 5 ft 9 in tall for a man?
No, 5 ft 9 in (175.3 cm) is almost exactly average for a US man, sitting right around the 50th percentile. It only reads as "tall" when compared against a shorter national average, or as short when compared against a taller one like the Netherlands.
What is the average height percentile?
The average height sits at the 50th percentile, the median of the bell curve. For US men that is about 5 ft 9 in (175.4 cm) and for US women about 5 ft 4 in (161.7 cm).
How is the height percentile calculated?
The tool converts your height to a z-score, z = (height - mean) / SD, then applies the normal CDF, CDF(z) = 0.5 x (1 + erf(z / sqrt(2))), and multiplies by 100. That gives the percentage of people you are taller than.
What does my height z-score mean?
The height z-score is how many standard deviations you are from average. A z of +1 is taller than about 84 percent of the group, a z of -1 is taller than about 16 percent, and a z of 0 is exactly average.
Which country has the tallest average height?
The Netherlands has the tallest recorded national average, with men averaging around 183.8 cm and women around 170.4 cm. That is roughly 8 cm taller than the US male average, which is exactly why the same height can rank very differently depending on the country you compare against.
Is the male height percentile different from the female one?
Yes. Men and women have different means and spreads, so the calculator uses a separate curve for each sex. Selecting the wrong one gives a very inaccurate rank.
Can I use this for a child or teenager?
No. These are adult figures. Children and teens should be assessed on an age and sex specific pediatric growth chart from a pediatrician, because their expected height changes with age rather than staying fixed like an adult average.
How accurate is this height percentile calculator?
It is a close statistical estimate, not an exact census figure. Real height data is only approximately normal and shifts slowly over generations, but modelling it as a bell curve using survey means and standard deviations matches published percentile tables well for adults.
