Calculate your healthy weight range based on BMI, height, age, and gender. Get personalized health recommendations and track your weight goals with our free, accurate calculator.
To lose weight safely, create a calorie deficit of 500-750 calories per day through diet and exercise.
To maintain your current weight, consume calories equal to your TDEE with balanced nutrition.
To gain weight healthily, create a calorie surplus of 300-500 calories per day with strength training.
This calculator provides general health information based on established BMI guidelines from WHO and CDC. It is not a substitute for professional medical advice, diagnosis, or treatment. Individual health needs vary. Always consult with a qualified healthcare provider, registered dietitian, or certified nutritionist before making significant changes to your diet or exercise routine, especially if you have medical conditions, are pregnant, or taking medications.
Healthy weight is a weight range that minimizes health risks and promotes overall wellness. It's not a single number but a range based on your height, calculated using Body Mass Index (BMI). A healthy BMI for adults is between 18.5 and 24.9, which corresponds to a weight range that reduces risks of chronic diseases like heart disease, type 2 diabetes, hypertension, and certain cancers. Maintaining a healthy weight improves energy levels, mobility, mental health, and overall quality of life.
Healthy weight is calculated using the BMI formula: weight (kg) divided by height (m) squared. For a healthy BMI range of 18.5-24.9, we calculate the minimum weight (18.5 × height²) and maximum weight (24.9 × height²) to give you a personalized healthy weight range. This range accounts for individual variation while maintaining optimal health. For example, someone 170cm (5'7") tall has a healthy weight range of 53-72kg (117-159 lbs).
Maintaining a healthy weight is crucial for disease prevention and longevity. Being underweight increases risks of malnutrition, weakened immune system, osteoporosis, and fertility issues. Being overweight or obese raises risks of heart disease, stroke, type 2 diabetes, high blood pressure, sleep apnea, joint problems, and certain cancers. Studies show that maintaining a healthy weight can add years to your life and significantly improve quality of life. It's not just about appearance—it's about health, energy, and vitality.
Healthy weight is influenced by multiple factors beyond just height:
These terms are related but distinct. Healthy weight is a range based on BMI 18.5-24.9 that minimizes health risks. Ideal weight uses specific formulas (Robinson, Devine, etc.) to calculate a target weight based on height and gender. BMI is the calculation method (weight/height²) used to determine both. Healthy weight is broader and more flexible, ideal weight is more specific, and BMI is the measurement tool. All three are useful for different purposes—use healthy weight for general wellness goals.
While BMI and healthy weight ranges are useful screening tools, they have limitations. BMI doesn't distinguish between muscle and fat—bodybuilders and athletes with high muscle mass may have high BMI but low body fat and be perfectly healthy. BMI also doesn't account for fat distribution (belly fat is riskier than hip fat) or body composition. Pregnant women, elderly individuals, and those with certain medical conditions need different assessments. Use BMI as a starting point, but consider body fat percentage, waist circumference, and overall health markers for a complete picture.
Reaching your healthy weight requires sustainable lifestyle changes, not quick fixes:
Maintaining healthy weight is often harder than reaching it. Success requires permanent lifestyle changes, not temporary diets. Continue eating balanced meals, exercising regularly, and monitoring your weight monthly. Allow for 2-3kg (5 lbs) fluctuation—daily weight varies due to water retention, food intake, and hormones. Focus on how you feel, your energy levels, and fitness performance rather than obsessing over the scale. Build sustainable habits you can maintain for life. If you regain weight, address it early with small adjustments rather than waiting for significant gain.
While our calculator provides scientifically-based estimates, individual health needs vary. Consult a doctor, registered dietitian, or certified nutritionist if:
Weight is just one indicator of health. Consider these additional metrics for a complete picture:
BMI Guidelines: World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC)
BMR Formula: Mifflin-St Jeor Equation (validated by American Dietetic Association)
Weight Loss Recommendations: National Institute of Health (NIH) and Academy of Nutrition and Dietetics
Health Risk Data: Based on epidemiological studies from peer-reviewed medical journals
This calculator uses evidence-based formulas and guidelines from recognized health organizations. Information is regularly updated to reflect current medical consensus.
A healthy weight is a weight range that minimizes health risks and promotes overall wellness. It's typically defined by a BMI (Body Mass Index) between 18.5 and 24.9 for adults. However, healthy weight also depends on factors like muscle mass, bone density, age, gender, and body composition. This range helps reduce risks of chronic diseases like heart disease, diabetes, and hypertension.
Healthy weight is calculated using BMI (Body Mass Index) formula: weight (kg) / height (m)². A healthy BMI range is 18.5-24.9. For your height, we calculate the minimum weight (BMI 18.5 × height²) and maximum weight (BMI 24.9 × height²) to give you a healthy weight range. This range accounts for individual variation while maintaining optimal health.
A healthy BMI for adults is between 18.5 and 24.9. BMI below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese. However, BMI has limitations—it doesn't account for muscle mass, bone density, or body fat distribution. Athletes with high muscle mass may have high BMI but be perfectly healthy. Use BMI as a screening tool, not a definitive health measure.
Your healthy weight depends on your height and BMI. For example: 160cm (5'3") = 47-64kg (104-141 lbs), 170cm (5'7") = 53-72kg (117-159 lbs), 180cm (5'11") = 60-82kg (132-181 lbs). Use our calculator to find your personalized healthy weight range based on your specific height, age, and gender.
Healthy weight is influenced by multiple factors: height, age, gender, body frame size, muscle mass, bone density, genetics, metabolism, activity level, and overall health conditions. Men typically have higher healthy weights than women due to greater muscle mass. Older adults may have slightly different healthy ranges. Body composition (muscle vs. fat) is more important than weight alone.
