Convert height units, view population percentile, and estimate child height percentiles
This height calculator converts between different height units — feet/inches and centimeters — and provides a simplified population percentile comparison. It can also estimate a child's height percentile based on age, helping parents and caregivers track growth trends. Understanding height distribution can be useful for medical assessments, clothing sizing, and general curiosity about where one stands relative to the broader population.
The percentile estimate uses a simplified model based on published CDC height distribution data for adults (separate by general population averages). For children, it references WHO growth standards by age. The calculator provides an approximate percentile, not a clinical diagnosis.
According to CDC data, the average adult male height in the US is approximately 5 ft 9 in (175 cm) and the average adult female height is approximately 5 ft 4 in (163 cm). These averages vary by age, ethnicity, and geographic region.
