This ideal weight calculator determines how much you should weigh based on height, gender, and frame size. There are several different formulas used to calculate ideal weight. However, there is no one perfect formula, so this ideal weight calculator uses several popular formulas to allow for easy comparison (with the name of each formula in brackets).
Ideal Weight Calculator Instructions
- To determine your frame size use theframe size calculator.
- Select if you want to calculate your ideal weight in pounds (US units) or in kilograms (metric).
- Simply enter your gender, frame size, and height. Then click calculate. To make another calculation, click reset.

This calculator is for adults. There are different formulas to determine a healthy weight for children.
As with all methods of determining ideal weight, this weightcalculator provides only an estimate. Ideal weight based on frame size may fall outside the healthy BMI range for petite, small-framed women and large-framed men.
However, aim to stay within your healthy BMI range, or speak to your doctor about what is a healthy weight for you. Your healthcare provider will be able to assess your body composition and health more accurately, such as by measuring your body fat percentage.
How Much Should I Weigh?
The above ideal weight calculator and charts highlight how “ideal” body weight might vary between individuals based on the size of their frame. But frame size is not the only factor to consider when determining what a healthy weight is for you.
Each of us is built differently. While two people may have the same height, they may have a different body types, size frame, and body fat distribution.
This means a healthy weight for one person might not be the same as someone else’s, and that for the same height two people can have a different healthy weight zone.
Find out your body type
View ideal weight only as a general guideline. The point of this ideal weight calculator and these weight charts is to highlight that one size does not fit all. So don’t try to compare yourself with others and don’t follow very restrictive diets just to reach a certain number on the scale. You want to achieve the healthiest, happiest weight that is realistic for you.
This weight calculator considers frame size, gender,and height. However, in addition there are other important factors that affect ideal weight.
Body Shape. How your body fat is distributed affects how much you should weigh. That is because excess deep belly fat is associated with an increased risk of health conditions such as heart disease, high blood pressure, type 2 diabetes, stroke, and some cancers. It is possible to fall in the healthy weight BMI category, but have too much belly fat. 123
People with an apple body shape carry more fat around the abdomen, which is associated with a greater risk of heart disease and type 2 diabetes.45
People with a “pear shape” carry more weight on their hips and thighs, which is linked with a lower risk of heart disease.6

Body Composition. Another disadvantage in just using ideal weight is that does not consider body composition. In other words it does not differentiate between fat and muscle.7
For example, an athletic person with a lot of muscle could fall in the overweight BMI zone, such as Arnold Schwarzenegger or Dwayne “The Rock” Johnson. On the other hand, a person who is lightly muscled might fall in the healthy BMI weight category, but have unhealthy levels of body fat.891011
Looking just at body weight alone is limiting.Therefore, use body weight, as well as some of the methods below to help you determine how much you should weigh.121314
Ideal Weight Alternatives
Use this ideal weight calculator in conjunction with other with other ways of determininghow much you should weigh, such as:
- Waist-to-hip ratio calculator. Waist-to-hip ratio compares waist measurement to hip measurement, and is a measure body fat distribution. Too much belly fat is associated with greater health risks.
- Body fat percentage, which estimates your total body fat. If you can, get your body fat percentage measured professionally. Alternatively, use thebody fat calculatorto get an estimate now.

What are the Formulas for Finding Ideal Weight?
Ideal weight formulas were originally developed foruse by doctors to calculate drug dosages or determine nutritional needs. This calculator uses the following formulas:
- Robinson Formula (1983)15
Male: 52 kg + 1.9 kg per inch over 5 feet
Female: 49 kg + 1.7 kg per inch over 5 feet - Miller Formula (1983)16
Male: 56.2 kg + 1.41 kg per inch over 5 feet
Female: 53.1 kg + 1.36 kg per inch over 5 feet - Hamwi Formula (1964)17.1819
Male medium frame: 48.0 kg + 2.7 kg per inch over 5 feet
Female medium frame: 45.5 kg + 2.2 kg per inch over 5 feet
For a small frame subtract 10%, for a large body frame add 10%. - Devine Formula (1974)2021
Male medium frame: 50.0 kg + 2.3 kg per inch over 5 feet
Female medium frame: 45.5 kg + 2.3 kg per inch over 5 feet
For a small frame subtract 10%, for a large body frame add 10%.
Body Mass Index
Body mass index is a popular method with health professionals for determining a healthy weight range. A higher BMI is associated with a higher level of body fat. Research shows that a higher BMI is associated with negative health consequences.222324 BMI is calculated dividing a person’s weight in kg by their height squared.
BMI = kg/m2
According to the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) a healthy BMI range is defined as 18.5–24.9 for adult men and women.2526 From this you can determine what a healthy weight range is at a specific height.
BMI has been around for over 200 years and this definition of a healthy weight is largely based on populations of European descent. However, research increasingly shows that a healthy BMI can vary between ethnic groups.
A narrower BMI range of 18.5–22.9 was proposed by the WHO for the Asia-Pacific region, which has been adopted by several Asian countries including South Korea, Singapore, and India. 27282930 Since 2022, this BMI range has also been adopted in England for most people of Asian, African, and Middle Eastern decent. According to their recommendations, this is because people with a “South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean family background are prone to central adiposity and their cardiometabolic risk occurs at a lower BMI.”31 It has not been adopted by the CDC, but is sometimes used in the United States to determine healthy weight for Asian Americans.32
Calculate your BMI
When determining your ideal weight, it’s worth remembering the significant limitations of it. For example, such formulas are based on the data of a large group of people, and so are not specific to you. As such they can only provide a general estimate. Furthermore, there is no one perfect formula that considers all the factors that influence ideal weight. So any formula that attempts to calculate this will have a some limitations.

For an overview of how much you shouldweigh, see the tables below. The normal weight column of the left is based on the standard healthy BMI range of 18.5-24.9, while the column on the right is based on the narrower health BMI range of 18.5-22.9.
