Body Mass Index (BMI): Females, Age 20-29
What these numbers mean
A value around 25.5 kg/m² is typical (50th percentile) for females in this age group. Scores above about 31.6 kg/m² fall near the 75th percentile or higher, indicating above-average performance. Scores below about 22.2 kg/m² fall near the 25th percentile; about 75% of the reference population scored higher.
These percentiles reflect the US population, so the same BMI would usually rank at a higher percentile in leaner populations.

Body Mass Index (BMI) Percentile Chart (kg/m²)
These percentiles are from the US, which has one of the highest obesity rates globally. A BMI of 25.5 kg/m² would typically fall around the 75th to 85th percentile in countries where mean adult BMI is 23 to 24 (e.g. Japan or South Korea).
This percentile chart shows how common a value is, not whether it is healthy.
