About Ideal Weight

There is no single "ideal" weight — healthy weight ranges vary by formula, body composition, age, and ethnicity. Our calculator shows results from four commonly used formulas: the BMI method (18.5–24.9 range), Devine formula (medical use), Robinson formula, and Miller formula.

For Indian and South Asian adults, some research suggests that health risks begin at lower BMI values (overweight at BMI 23+). Use these numbers as a general guide and consult a healthcare provider for personalised advice.

Frequently Asked Questions
For a 170 cm male, the healthy BMI range gives approximately 53–72 kg. The Devine formula suggests 67 kg, Robinson suggests 66 kg, and Miller suggests 63 kg. The average across formulas is around 63–67 kg.
No. Ideal weight varies by body frame size (small, medium, large), muscle mass, bone density, and age. Athletes may weigh more than the ideal range due to muscle while still being perfectly healthy.
For South Asians, many health organisations recommend targeting the lower end of the healthy BMI range (18.5–23) due to higher risk of metabolic disease at lower BMI values compared to Western populations.
