Looking to lose a few pounds sustainably? Before starting any diet, determining your ideal height-to-weight ratio is essential. As nutrition experts recommend, this longstanding guideline—known as the Lorentz formula—offers a reliable starting point for healthy, effective weight management.
Calculate your target weight in seconds with this simple, trusted method.

For women, the formula is: Height in cm - 100 - (Height - 150) / 2.
Example: For a woman who is 1.60 meters (160 cm) tall: 160 - 100 - (160 - 150) / 2 = 160 - 100 - 10 / 2 = 55 kg.
For men, divide by 4 instead of 2.
Example: For a man who is 1.80 meters (180 cm) tall: 180 - 100 - (180 - 150) / 4 = 72.5 kg.

That's it—you now know how to quickly calculate your ideal weight based on your height using this expert-backed formula.
Simple and practical, right? No advanced math required.
With your target in hand, you can pursue a healthy weight without compromising well-being.
