Height Percentile Calculator
Find out what percentile your height falls in compared to your peers. Enter your height, gender, age, and country to see what percentage of people of the same sex and background are shorter or taller than you. Supports infants, children, teens, and adults. Works in feet and inches or centimeters.
How to Use This Calculator
Select your unit system, enter your height, choose your biological sex, enter your age in years and months, and select the country whose population you want to compare to — or leave it as The World for a global comparison. Press Calculate Height Percentile to see your result.
For children under 2 years old, the calculator automatically uses the WHO world reference and the country field is locked. For ages 2–19, it uses US CDC growth chart data and the country is locked to United States. For adults 20 and older, all countries are available.
How Height Percentile Is Calculated
Height in human populations follows an approximately normal (bell-curve) distribution. Given a known mean and standard deviation for a reference population, the cumulative distribution function (CDF) tells us what fraction of the population is shorter than a given height — that fraction, expressed as a percentage, is the percentile.
Percentile = CDF(height, mean, SD) × 100
Example — male, 5′ 10″ (177.8 cm), United States:
z = (177.8 − 175.4) ÷ 7.6 ≈ 0.316
Percentile ≈ 62.4th
A result of 62.4 means the person is taller than about 62% of US adult males and shorter than the remaining 38%.
Data Sources
The calculator uses three reference datasets depending on age:
| Age range | Data source | Country availability |
|---|---|---|
| 0–23 months | WHO Child Growth Standards | The World (locked) |
| 2–19 years | CDC NHANES 2011–2014 | United States (locked) |
| 20+ years | NCD-RisC 2020 + national surveys | 130+ countries |
Adult country data comes from the NCD Risk Factor Collaboration (2020) study covering the most recent birth cohort. Heights vary significantly by country due to genetic and environmental factors, so selecting the country where you spent your childhood gives the most meaningful comparison.
