Ideal Weight Calculator

Ideal weight calculator shows the ideal weight of a person of a certain height and sex.

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 for you. It will help you determine your ideal body weight basing 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 that bases on the BMI.

How much should I weight?

There many many ways to estimate the ideal weight. Truth be told, none of them is perfectly accurate, as there are a lot of factors influencing it. For example, people with a lot of muscle mass (and high lean body mass tend to weight more than indicated by the results you obtain.

Our ideal body weight calculator uses four different formulas to find the ideal weight alongside with the BMI estimation. While the four formulas listed below give you only one number that you should get as close to as possible, 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 ideal weight is BMI, the body mass index. It is calculated according to the formula BMI = weight/height². The most healthy range of BMI is between 18.5 and 24.9. Our ideal weight calculator finds the weight range appropriate 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 the use of 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.
