Understanding BMI Ranges & Ideal Body Weight Definition

A BMI of between 20 and 25 is considered to be an ideal weight. The ideal body weight definition represents the optimal weight range for health outcomes based on your height. You can use this table to determine your acceptable weight range for your height (in cm), by finding the weight corresponding to a BMI level of 20 and 25. For example, if you are 160cm tall, your ideal weight range is between 51.2 and 64.0 kg, and you are obese if you are above 76.8 kg.

Ideal Body Weight Formula Explained

Our calculator uses the scientifically proven ideal body weight formula: BMI = weight(kg) / height(m)². For optimal health:
