What is a Healthy Weight?
A healthy weight is one associated with a lower risk of chronic disease — most commonly benchmarked by the BMI range of 18.5 to 24.9. Rather than chasing one exact number, this calculator shows the full healthy band for your height and where your current weight sits inside (or outside) it. For a single point-estimate target adjusted by body frame instead, see our ideal weight calculator, or check your BMI directly.
The Six Formulas Explained
BMI Range: Weight = BMI × Height(m)² for BMI 18.5–24.9Hamwi: Male 48.0kg + 2.7kg/in over 5ft · Female 45.5kg + 2.2kg/in over 5ftDevine: Male 50.0kg + 2.3kg/in over 5ft · Female 45.5kg + 2.3kg/in over 5ftRobinson: Male 52.0kg + 1.9kg/in over 5ft · Female 49.0kg + 1.7kg/in over 5ftMiller: Male 56.2kg + 1.41kg/in over 5ft · Female 53.1kg + 1.36kg/in over 5ftWHO Range: Same as the BMI Range above (18.5–24.9)Limitations: no formula perfectly fits every body. A muscular athlete can carry a “high” BMI while having very low body fat, and older adults who’ve lost muscle can read as normal-weight while carrying excess fat. Treat every number here as a guideline, not a strict target.
🥗
Sustainable Diet
A modest 300-500 kcal/day deficit produces steady, maintainable loss without the rebound risk of crash diets. Use our calorie calculator to find your number.
🏋️
Strength Training
Building muscle can hold the scale steady or even raise it slightly while body fat drops — track how clothes fit, not just the number.
🚶
Daily Movement
10,000 steps a day burns roughly 400-500 extra calories for most adults — often easier to sustain than structured cardio sessions.
📊
Track Weekly, Not Daily
Weigh yourself at the same time each week. Daily fluctuations of 1-3kg from water, food, and hormones can mask the real trend.
