Calculate your ideal body weight using Hamwi, Devine, Robinson, and Miller formulas. Get your BMI-based healthy weight range optimized for Indian body types. Free and instant.
| Formula | Ideal Weight |

Each formula uses your height and gender to estimate an ideal body weight:
The BMI healthy range is calculated as 18.5 × height² to 24.9 × height². This gives the weight range where your BMI falls in the "normal" category. Use the range across all formulas as a general guide, not a strict target.
| BMI Range | Category | Health Risk |
|---|---|---|
| Below 18.5 | Underweight | Increased risk of malnutrition |
| 18.5 – 24.9 | Normal (Healthy) | Low risk |
| 25.0 – 29.9 | Overweight | Increased risk of heart disease |
| 30.0 – 34.9 | Obese (Class I) | High risk |
| 35.0 – 39.9 | Obese (Class II) | Very high risk |
| 40.0 and above | Obese (Class III) | Extremely high risk |
Indian body types tend to have higher body fat percentage at the same BMI compared to Western populations. Many doctors recommend a lower BMI range of 18-23 (instead of 18.5-24.9) for South Asians.
| Height | Healthy Range (BMI 18.5-24.9) | Indian Recommended (BMI 18-23) |
|---|---|---|
| 5'0" (152 cm) | 42.5 - 57.5 kg | 41.6 - 53.2 kg |
| 5'3" (160 cm) | 47.3 - 63.9 kg | 46.1 - 59.0 kg |
| 5'5" (165 cm) | 50.4 - 68.1 kg | 49.0 - 62.7 kg |
| 5'7" (170 cm) | 53.5 - 72.2 kg | 52.0 - 66.5 kg |
| 5'9" (175 cm) | 56.7 - 76.6 kg | 55.1 - 70.4 kg |
| 5'11" (180 cm) | 59.9 - 81.0 kg | 58.3 - 74.5 kg |
| 6'0" (183 cm) | 62.1 - 83.7 kg | 60.2 - 76.7 kg |

No single formula is perfect for everyone. The BMI-based range (18.5-24.9) is the most widely used. The range across all four formulas gives a more realistic healthy weight zone.
Each formula was developed from different populations and studies. Hamwi (1964), Devine (1974), Robinson (1983), and Miller (1983) all used slightly different methodologies. Use the range across all formulas.
No, these formulas do not distinguish between muscle and fat. Athletes and bodybuilders may weigh more than their "ideal" weight due to higher muscle mass. Focus on body composition, not just the number.
The BMI-based healthy range is the best guide. For example, at 170 cm: healthy range is 53.5-72.2 kg (BMI 18.5-24.9). Use this calculator to find your specific range.
No. These are estimates. Focus on how you feel, your energy levels, and overall health markers rather than hitting a specific number. A range is more useful than a single target.
For a 5'6" (168 cm) Indian male, the healthy weight range is approximately 52-70 kg (BMI 18.5-24.9). For Indian body types, many doctors recommend 50-65 kg (BMI 18-23) due to higher body fat at the same BMI compared to Western populations.
There is no India-specific formula. Use the standard Hamwi, Devine, Robinson, or Miller formulas. However, for Indian body types, aim for the lower end of the BMI healthy range (18-23 instead of 18.5-24.9) as South Asians tend to have higher body fat percentage at the same BMI.
The Hamwi formula: Men = 48 kg + 2.7 kg per inch over 5 feet. Women = 45.5 kg + 2.2 kg per inch over 5 feet. The BMI range: Weight = BMI × height². At 170 cm and BMI 22 (mid-normal): 22 × 1.70² = 63.6 kg.
"Ideal weight" is a single number from a formula (like Hamwi or Devine). "Healthy weight" is a range based on BMI (18.5-24.9). The healthy weight range is more practical because it accounts for individual variation in bone density, muscle mass, and body composition.
