Ideal Weight Calculator: How much should I weigh?
There many many ways to estimate your ideal weight. Please note that they are not 100% accurate, as there are a lot of factors influencing the data. For example, for people with a lot of muscle mass (and high lean body mass), their ideal weight will tend to be more than indicated by the results they obtain.
Our ideal body weight calculator uses four different formulas to find your ideal weight, as well as giving you your BMI . While the four formulas listed below give you only one number that you should be aiming for, BMI gives you a certain weight range you should be in.
For men, the ideal weight calculator uses the following equations:
- Robinson formula:
52 kg + 1.9 kg per every inch over 5 feet
- Miller formula:
56.2 kg + 1.41 kg per every inch over 5 feet
- Hamwi formula:
48.0 kg + 2.7 kg per every inch over 5 feet
- Devine formula:
50.0 kg + 2.3 kg per every inch over 5 feet
For women, the ideal weight calculator uses the following equations:
- Robinson formula:
49 kg + 1.7 kg per every inch over 5 feet
- Miller formula:
53.1 kg + 1.36 kg per every inch over 5 feet
- Hamwi formula:
45.5 kg + 2.2 kg per every inch over 5 feet
- Devine formula:
45.5 kg + 2.3 kg per every inch over 5 feet
Height weight chart and BMI
The last indicator of an individuals ideal weight is BMI, short for Body Mass Index. It is calculated according to BMI = weight/height²
. The optimal, healthy range for BMI is between 18.5 and 24.9. Our ideal weight calculator converts this back into weight, presenting to you the range of appropriate weights for your height.
You can also take a look at a height-weight chart that shows the ranges of underweight, normal and overweight for various heights:

Limitations of our IBW calculator
Remember that the values found with our ideal body weight calculator are not one hundred percent valid for all. As long as you are in the BMI normal weight range, you are fine – don’t go on a strict diet just to reach that specific number!
