BMI Comparison Tool

Compare your BMI with national and regional averages across the UK to understand where you stand in relation to different demographic groups.

Remember that BMI is just one measure of health. Individual health needs vary, and BMI comparisons should be used for context only, not as a definitive health assessment.

Understanding BMI Comparisons

What Do These Comparisons Mean?

Comparing your BMI with population averages provides context for your individual measurement. However, it’s important to remember:

Population averages don’t determine what’s healthy for you as an individual
Having a BMI that’s “better than average” doesn’t necessarily mean it’s optimal for health
BMI distribution varies significantly across different demographic groups
BMI is just one health metric and should be considered alongside other factors

The NHS recommends maintaining a BMI between 18.5 and 24.9 for most adults, regardless of what’s “average” in your demographic group.
