Calculate your Body Mass Index and see what category it falls into.
Body Mass Index (BMI) is weight in kilograms divided by height in meters squared (kg/m²). It's a quick, rough measure of healthy weight relative to height. BMI does not distinguish muscle from fat — athletes often score "overweight" despite low body fat. Always consult a doctor for medical advice.
Underweight: < 18.5 — Normal: 18.5–24.9 — Overweight: 25–29.9 — Obese: 30+. Higher BMI is associated with increased risk of cardiovascular disease, type 2 diabetes, and other conditions.
BMI is a general screening measure based on height and weight. It doesn't distinguish muscle from fat, so it's less reliable for athletes, older adults, or people with unusual body composition.
Roughly 18.5–24.9 is classified as a healthy weight range for most adults; the tool shows exactly where your number falls against the underweight, healthy, overweight, and obese categories.
