Ideal Body Weight Calculator
Calculate Your Healthy Weight Range Based on Scientific Formulas
Understanding Ideal Body Weight
The concept of ideal body weight dates back to the late 19th century when life insurance companies began analyzing mortality data in relation to body weight. However, it was Dr. G.J. Hamwi in 1964 who created the first widely-used formula for calculating ideal body weight during a diabetes conference. His simple calculation – 100 pounds for the first 5 feet of height plus 5 pounds for each additional inch for women (106 pounds + 6 pounds for men) – became the foundation for modern weight assessment.
Subsequently, other formulas were developed including the Devine formula (1974) which adjusted calculations for medication dosing, and the Robinson formula (1983) which refined these estimates. Today, ideal body weight calculations are used alongside BMI (Body Mass Index) to assess healthy weight ranges and potential health risks. These calculations help healthcare professionals determine appropriate weight goals for patients and identify potential weight-related health issues.
Understanding your ideal body weight provides valuable insight into your health status. While not a perfect measure, it serves as a practical starting point for setting realistic weight management goals. For instance, being significantly above your ideal weight range increases your risk for conditions like heart disease, diabetes, and hypertension. Conversely, being significantly underweight can indicate nutritional deficiencies or other health concerns.
Your ideal body weight can vary by up to 15% based on your body frame size? People with larger frames may have a higher ideal weight than those with smaller frames, even at the same height. This is why body frame assessment is an important part of weight evaluation!

Your Ideal Weight Analysis
What Your Results Mean:
Your ideal weight range of 60-68 kg corresponds to a BMI of 20-23, which falls within the healthy range recommended by the World Health Organization. Maintaining a weight in this range significantly reduces your risk for weight-related health conditions.
Interpretation Guide:
| BMI Category | BMI Range | Health Risk | Recommendation |
|---|---|---|---|
| Underweight | < 18.5 | High (Nutritional deficiency, osteoporosis) | Consult healthcare provider, focus on healthy weight gain |
| Normal | 18.5 – 24.9 | Lowest | Maintain current weight through balanced diet and exercise |
| Overweight | 25.0 – 29.9 | Increased (Heart disease, diabetes) | Moderate weight loss through diet and exercise |
| Obese I | 30.0 – 34.9 | High | Significant lifestyle changes, medical consultation |
| Obese II | 35.0 – 39.9 | Very High | Medical supervision for weight management |
Ideal Weight Reference (Adults)
| Height | Women (kg) | Men (kg) |
|---|---|---|
| 150 cm (4’11”) | 45.5 – 52.6 | 48.1 – 55.8 |
| 160 cm (5’3″) | 51.3 – 59.4 | 54.4 – 63.0 |
| 170 cm (5’7″) | 57.1 – 66.2 | 60.8 – 70.3 |
| 180 cm (5’11”) | 63.0 – 73.0 | 67.1 – 77.6 |
| 190 cm (6’3″) | 68.9 – 79.8 | 73.5 – 85.0 |
Healthy Weight Management Strategies
Based on your ideal weight calculation, we recommend the following approach to achieve and maintain a healthy weight:
Nutrition Plan
Adopt a balanced approach to eating that supports sustainable weight management:
- Portion control: Use smaller plates and be mindful of serving sizes to avoid overeating.
- Nutrient density: Focus on whole foods like vegetables, fruits, lean proteins, and whole grains.
- Hydration: Drink at least 2 liters of water daily, as thirst is often mistaken for hunger.
- Regular meals: Maintain consistent eating patterns to stabilize metabolism and energy levels.
Physical Activity Recommendations
Combine different types of exercise for optimal results:
- Aerobic exercise: 150 minutes per week of moderate-intensity activities like brisk walking or cycling.
- Strength training: 2 sessions weekly to build muscle mass and boost metabolism.
- Daily movement: Aim for 8,000-10,000 steps daily to increase non-exercise activity thermogenesis (NEAT).
- Flexibility and balance: Include activities like yoga or tai chi 2-3 times per week.
Lifestyle Factors
- Quality sleep: Aim for 7-9 hours nightly – poor sleep disrupts hunger hormones.
- Stress management: Practice mindfulness, meditation, or deep breathing techniques.
- Regular monitoring: Track your progress with our Weight Loss Planner tool.
- Professional guidance: Consult with a dietitian or healthcare provider for personalized advice.
