Ideal weight calculator

“How much should I weigh for my height?” is one of the most common health questions. This ideal weight calculator answers it two ways: the healthy weight range based on the BMI cut-offs used in India (18.5–22.9), and the four classic ideal body weight formulas doctors and dietitians use. Add your current weight to see how far you are from the range. Remember that a range — not one exact number — is the healthy goal.

How to use it

  1. Choose your sex and enter your height in centimetres.
  2. Optionally enter your weight to see the gap to the healthy range.

Example

A woman 160 cm (5 ft 3 in) tall has a healthy range of 47.4–58.6 kg by Indian BMI cut-offs. The formulas give between about 52.1 kg (Hamwi) and 57.2 kg (Miller) — all inside that range. At 65 kg she would be about 6.4 kg above it. Check your BMI and body fat with the BMI calculator and body fat calculator, and plan meals with thecalorie calculator.

Frequently asked questions

What is my ideal weight?
There is no single perfect number — a healthy range is more useful. For Indians and other Asians, a BMI of 18.5–22.9 is considered the healthy range (lower than the WHO global 18.5–24.9), because health risks such as diabetes start at lower BMIs in South Asians.
Why do the formulas give different answers?
Robinson, Miller, Devine and Hamwi were each created for different purposes (several originally for drug dosing) from different groups of people. Their spread shows that “ideal” is a range, not a point.
Do these formulas work for children?
No. They are for adults only. Children’s healthy weight is judged with growth charts and BMI-for-age percentiles — ask your paediatrician.
I’m muscular — does this apply to me?
Height-based formulas ignore muscle, so athletes and gym-goers may weigh more than the range while being lean and healthy. Body fat percentage and waist size are better guides for you.
