Ideal Weight Calculator

The concept of an ideal body weight has been used in medicine for decades to help determine drug dosages, assess nutritional status, and set health goals. This calculator uses the Devine formula, one of the most widely referenced equations, which estimates ideal weight based on height and sex.

The Devine Formula

For men, the formula is 50 kg + 2.3 kg for each inch over 5 feet. For women, it is 45.5 kg + 2.3 kg for each inch over 5 feet. This calculator converts your height from centimetres to inches automatically. Keep in mind that this formula was originally developed for pharmaceutical dosing and may not reflect the healthiest weight for every individual.

Beyond Ideal Weight

No single number can define the perfect weight for everyone. Body composition, muscle mass, bone density, and overall fitness all play important roles. A muscular person may weigh more than the Devine formula suggests yet be perfectly healthy. Use this result as one of several reference points, alongside BMI, waist circumference, and how you feel in your daily life. Consult a healthcare professional for personalised advice.

Frequently Asked Questions

How do you find your ideal weight?

You can check if you have a healthy weight for your height using a BMI calculator or by calculating your BMI with the formula: BMI = weight (kg) / heightยฒ (m). For example, a person weighing 65 kg and 1.75 m tall: 65 kg / (1.75 m x 1.75 m) = BMI 21.2.

What weight suits my height?

BMI is calculated based on height and weight. To find your BMI, multiply your height in metres by your height in metres and divide your weight in kg by that number. For example, if you weigh 70 kg and are 1.75 m tall: 70 kg / (1.75 m x 1.75 m) = 22.86, giving a BMI of 22.86.

Why does my weight fluctuate by 2 kg?

Body weight is not a static number. It depends heavily on what you have eaten, how much you have eaten, how often you use the bathroom, etc. A fluctuation of 3-4 kg may seem large but is by no means abnormal.

What is the difference between ideal weight and BMI?

Ideal weight is typically calculated using formulas like the Devine formula and gives a specific kilogram figure based on your height and sex. BMI, on the other hand, is a ratio comparing your actual weight to your height. BMI provides a range (e.g. 18.5-24.9 for normal weight), while ideal weight gives a single number. Both are indicative and should be supplemented with other health measures.
