Discover your healthy weight range using four popular scientific formulas. Understand how height, gender, and body frame contribute to your ideal weight.
Your Ideal Weight Range is
65.2 - 66.7 kg
(143.7 - 147.1 lbs)
Based on a healthy BMI of 18.5-24.9, your weight should be between 53.5 kg and 72.0 kg.
The concept of an "ideal weight" is a guide, not a strict rule. It provides a healthy and sustainable weight range based on your height, gender, and to some extent, your body frame. Using multiple formulas gives a more balanced view, as each was developed with slightly different assumptions. This calculator uses four of the most recognised formulas: Devine, Robinson, Miller, and Hamwi, to provide a comprehensive estimate.
These formulas were originally created by doctors and scientists to help with medical calculations, but they have become popular for general health assessment. They primarily use height as the main determinant, with adjustments for gender. For example, the Devine formula, one of the most popular, sets a base weight for a 5-foot tall person and adds a set amount for each additional inch. Our calculator also includes an adjustment for body frame size, which can account for differences in bone structure and natural build.
It is important to view these results in the context of your overall health. Factors like body composition (muscle vs. fat), lifestyle, and genetics all play a significant role. A healthy BMI range is also provided as a broader reference. For personalised advice, it is always best to consult a healthcare professional. For more insight into your body composition, consider using our Body Fat Percentage Calculator.
