How is BMI Calculated?

It's straightforward: BMI = weight (kg) / [height (m)]². For example, at 1.60 m and 50 kg: 50 / (1.60)² = 19.5.

Results range from 16.5 to 40. Use the WHO-inspired table below to evaluate health risks and decide on next steps.

Interpreting Your Results

Now you can calculate your BMI with confidence! If you're in the normal range (18.5–25) but have stubborn areas like a belly or hips, swap snacking for targeted strength training—no diet needed.
