Ideal Weight Science
Ideal Weight Calculator — Ideal Body Weight for Height Free
This free ideal weight calculator uses four established medical formulas — Devine, Hamwi, Robinson and Miller — to calculate your ideal body weight based on height and gender. It also provides Indian BMI-based ranges (18.5–22.9) as recommended by ICMR, which differ from Western healthy weight ranges. The Devine formula, the most widely used, was originally validated in clinical research published on NIH/PubMed.
There is no single "ideal weight" — different medical systems use different formulas developed for different purposes. The average of all four gives the most reliable estimate. Ideal weight for height varies by body frame, muscle mass and ethnicity. This calculator accounts for all three.
Ideal Weight for Women
The healthy weight calculator for women uses the Devine formula: 45.5 + 2.3 × (height in inches − 60). For a 160cm woman, this gives approximately 51.4 kg. The Robinson formula gives 53.5 kg. The average across all formulas is approximately 52–55 kg for medium frame. The ICMR Indian range for 160cm women is 47.4–58.8 kg (BMI 18.5–22.9).
Ideal Weight for Men
The ideal weight calculator for men uses the Devine formula: 50 + 2.3 × (height in inches − 60). For a 170cm Indian man, this gives approximately 63.5 kg. The average of all four formulas is typically 62–68 kg for medium frame. The ICMR Indian range for 170cm men is 53.5–66.2 kg (BMI 18.5–22.9).
Ideal Weight Chart
Ideal Weight Chart — What Should I Weigh for My Height?
The question what should I weigh is best answered by both medical formula ranges and Indian BMI-based ranges. Use the ideal weight calculator above for your personalised number, or reference this ideal weight chart for common heights:
| Height | Ideal Weight (Men) | Ideal Weight (Women) | Indian BMI Range |
|---|---|---|---|
| 155 cm | 50–56 kg | 46–52 kg | 44.4–55.0 kg |
| 160 cm | 54–60 kg | 49–55 kg | 47.4–58.7 kg |
| 165 cm | 57–63 kg | 52–58 kg | 50.4–62.5 kg |
| 170 cm | 60–67 kg | 55–61 kg | 53.5–66.3 kg |
| 175 cm | 63–70 kg | 58–64 kg | 56.7–70.3 kg |
| 180 cm | 67–74 kg | 62–68 kg | 59.9–74.3 kg |
These ranges assume a medium body frame. Small frames should aim for the lower end; large frames for the upper end. The ideal weight calculator kg above gives you a personalised result for your exact height and frame.
India Standards
Ideal Weight India — ICMR-Recommended Weight Range for Indians
Healthy Weight Calculator for Indians
The ideal weight for Indians differs from Western standards because South Asians develop metabolic complications at lower BMI values. The Indian Council of Medical Research (ICMR) recommends a BMI of 18.5–22.9 as the healthy range for Indians — compared to 18.5–24.9 in Western guidelines as per WHO Expert Consultation on Asian BMI cutoffs.
This means the healthy weight calculator result for Indians is typically 2–4 kg lower than for people of the same height from Western populations. A 170cm Indian man should aim for 53–66 kg rather than the 53–72 kg Western range. Use the ideal weight calculator kg above for your personalised number. For anyone outside India, this also functions as a normal weight calculator — the WHO BMI 18.5–24.9 range applies universally. For ideal weight women in India, the ICMR range gives a target approximately 3–5 kg lower than Western charts. For ideal weight men in India, the same applies — always use Indian cutoffs for accurate results.
- Indians accumulate visceral fat at lower BMI levels than Europeans
- Type 2 diabetes risk rises at BMI 23+ for Indians vs BMI 27+ for Europeans
- Cardiovascular risk is elevated at waist >90cm (men) and >80cm (women)
- ICMR recommends not exceeding BMI 22.9 for optimal metabolic health in Indians
Body Frame Size
Ideal Body Weight Calculator — Frame Size Adjustments Explained
The ideal body weight calculator gives different results based on your body frame (small, medium, large). Frame size is determined by wrist circumference relative to height — a rough but useful proxy for bone density and skeletal structure. People with larger frames naturally carry more lean mass and can healthily maintain a higher body weight.
Most medical formulas — including Devine, Hamwi, Robinson and Miller — were developed on Western populations. They may slightly underestimate ideal weight for large-framed Indians or overestimate for small-framed individuals. Use the formula range as a target zone rather than a precise number. Body composition — your muscle-to-fat ratio — matters more than hitting an exact weight figure.
