Ideal Weight Calculator India
Find your ideal body weight using the Indian-adjusted formula — calibrated for smaller Indian frames, not Western averages. Compare with the Western target side by side.
Why Indian Ideal Weight Is Different
Western ideal weight formulas were developed on North American and European populations with larger average frame sizes. Indian adults have smaller skeletal frames on average — meaning the Indian target weight is typically 2–4 kg lower than what Western formulas suggest.

Understanding Your Ideal Weight Result
Ideal body weight is a reference range — the weight at which most people of your height, gender, and frame are statistically healthiest. It is not a target you must hit precisely, but a useful benchmark alongside BMI and waist circumference.
The Indian formula used here is the Modified Devine formula, adjusted for Indian body composition. It uses a base of 50 kg for men and 45.5 kg for women at 152.4 cm, adding 0.9 kg per centimetre above that baseline. Frame size adjusts the target by ±2.5 kg — smaller frames carry less bone mass.
Ideal weight is most useful when your actual weight is significantly above or below the range. If you are within or close to the range, focus on energy levels, fitness, and blood markers rather than the exact number on the scale.
Why Indian Ideal Weight Differs From Western Formulas
The Hamwi and original Devine formulas were developed on North American and European populations. Average Indian adults have smaller skeletal frames, lower bone density, and different fat-to-muscle ratios compared to Western populations of the same height, as documented in ICMR anthropometric reference data.
An Indian man at 170 cm with a medium frame has an Indian ideal weight of approximately 65–68 kg. The Western Hamwi formula suggests 67–70 kg for the same person — a 2–3 kg difference that is meaningful at the margins of healthy weight assessment.
Athletes and people with high muscle mass will appear to exceed these targets despite excellent health — ideal weight formulas cannot distinguish fat from muscle. Use our BMI Calculator alongside this tool for the Indian ICMR classification.
When to Speak With Your Doctor
Speak with your doctor if:
- Your weight is significantly above the ideal range — combined with a high Indian BMI (≥ 23), this warrants a metabolic health check including fasting glucose, HbA1c, and lipid profile.
- Your weight is significantly below the ideal range — unexplained weight loss or persistent underweight may signal nutritional deficiency, thyroid conditions, or other causes worth investigating.
- You are unable to maintain the range — a registered dietitian can create an Indian diet plan suited to your health goals without extreme restriction.
Your waist circumference is often a more meaningful indicator of metabolic risk than scale weight — Indian cutoffs are ≥ 90 cm for men and ≥ 80 cm for women. Check your Diabetes Risk using the IDRS which factors in waist size.
