Choose your gender and type in your height, then press Calculate. You will see your ideal weight from the Devine formula and the wider healthy range that corresponds to a BMI of 18.5–24.9.
Formula
Devine formula — Women: ideal weight = 45.5 kg + 2.3 kg for every inch over 5 feet. The healthy range is the weight that gives a BMI between 18.5 and 24.9 for your height.
Frequently asked questions
Is the Devine ideal weight the same as a healthy weight?
Not exactly. Devine gives one target number, while the healthy BMI range gives a band. Many people aim for the band rather than a single figure.
Does ideal weight depend on age or build?
The Devine formula only uses height and gender. Age, muscle mass and frame size also matter, which is why the healthy range is a more useful guide for most people.
What if I am very tall or short?
The formula works for most adult heights. If you are far outside the usual range, treat the result with extra caution and ask a professional.
