For most adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese. These thresholds apply to adults aged 18–65 and may vary by ethnicity. Children should use age-specific BMI percentile charts.
BMI is a useful screening tool but does not directly measure body fat, muscle mass, or fat distribution. For a more complete picture, combine BMI with your waist-to-height ratio, activity level, and blood markers. Always consult a healthcare professional for a full assessment.
BMI = weight (kg) ÷ height² (m²). This tool also uses the Deurenberg formula to estimate body fat percentage and the Devine formula for ideal weight range. All calculations run entirely in your browser — no data is sent to any server.
