Common mistakes to avoid

  • Entering total inches in the feet field.
  • Using BMI to judge muscular athletes, where it overestimates fatness.
  • Comparing children’s BMI with adult categories.
  • Treating BMI as a diagnosis rather than a screening number.

💡 Practical tip: BMI does not distinguish muscle from fat — the waist-to-height ratio calculator is a useful companion measure.
