Body Mass Index (BMI): Males, Age 40-49

What these numbers mean

A value around 28.9 kg/m² is typical (50th percentile) for males in this age group. Scores above about 33.5 kg/m² fall near the 75th percentile or higher, indicating above-average performance. Scores below about 25.7 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.

These percentiles are from the US, which has one of the highest obesity rates globally. A BMI of 28.9 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.
