# Ideal Weight Calculator

If you are really concerned about your health or your looks and want to know how much you should weigh, this ideal weight calculator is the tool for you. It will help you determine your ideal body weight based on your height and sex. Read on to learn the different formulas for calculating your IBW (ideal body weight) and how to interpret the results. We will also explain how to use the healthy weight chart, which is based on BMI.

## How much should I weight?

There many many ways to estimate somebodies ideal weight. Truth be told, none of them is perfectly accurate, as there are a lot of factors influencing it. 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!

Also, our IBW calculator is valid for adults only. Don't use it to find the proper weight range of kids - consult a specialist instead. Also, don't use it if you are pregnant. Use pregnancy weight gain calculator instead!
