Method and sources
One inch is exactly 2.54 cm, so inches = cm ÷ 2.54 and feet = inches ÷ 12. Display heights are rounded to the nearest half inch.
Percentiles use the CDC adult median and spread for each sex. Country comparisons use the 69 countries in this site's dataset, a subset of the roughly 200 in the full NCD-RisC release. See the methodology for details.
