Ideal Weight Calculator

Find your healthy weight range and ideal weight for your height.

Last updated: 8 Aug 2026

Quick answer

A healthy weight is best seen as a range for your height (BMI 18.5–24.9). For example, at 170 cm the healthy range is about 53–72 kg. The Devine formula also gives a reference ideal: men 50 + 2.3 kg per inch over 5 ft; women 45.5 + 2.3 kg per inch. Enter your height above.

There is no single "perfect" weight, so this ideal weight calculator shows a healthy weight range for your height (based on the healthy BMI band of 18.5–24.9), alongside the classic Devine reference ideal weight.

How to find your ideal weight

  1. 1 Select your gender.
  2. 2 Enter your height in centimetres.
  3. 3 We compute the healthy range from the BMI band and the Devine ideal.
  4. 4 See your healthy weight range and reference ideal weight.

Frequently asked questions

What is a healthy weight for my height?
It is the weight range that keeps your BMI between 18.5 and 24.9. At 170 cm, for example, that is roughly 53–72 kg.
What is the Devine formula?
A clinical reference: ideal weight = 50 kg (men) or 45.5 kg (women) + 2.3 kg for every inch over 5 feet of height.
Is ideal weight the same as a goal weight?
Not necessarily — it is a healthy reference. Body composition, muscle mass and health markers matter too.
