What is the Ideal Weight Calculator for?
The Ideal Weight Calculator is a measurement instrument that is easy and convenient to use, helping to compute weights for various purposes.
Medical purposes
Ideal body weight formulas were initially invented for use in the medical field; thus, medical purposes are mentioned first. In the first stage of its appearance, IBW was mainly used to calculate drug dosages for patients. The origin and history of IBW have clearly expressed its roles in such aspects.
Sports
Bodyweight has a significant impact on the power, speed, or endurance of people who participate in sports competitions. Thus, IBW Calculator is also used for many sports involving weights or classifying athletes based on weights.
Normal use
In general, knowing your ideal weight can help you improve your health and life. When you know how much you should weigh, you can choose your suitable fitness and nutrition for a healthier body.
For your detailed view, the following sections will provide specific information about the parts of our Ideal Weight Calculator, namely, Units (Fundamental Factors), Formulas, and Healthy BMI Range.
Calculating your ideal weight is an important step towards maintaining good health. You can use the ideal weight calculator for 5’7 height to determine your healthy weight range and track your progress. This calculator takes into account your gender, height, and age to provide a personalized result that can help you make informed decisions about your diet, exercise, and overall lifestyle.
Fundamental factors for Ideal Weight
Normally, people usually judge that someone has an ideal body weight via his or her appealing visual appearance. However, IBW, emerging from medical purposes, is not really related to how somebody looks.
There are many matters that can affect the ideal body weight of someone. This part will offer information on the main factors contributing to the body’s ideal weight, which are used in forming our Ideal Weight Calculator.
Besides the under-listed factors, several other elements can also affect the ideal weight, such as muscle to fat ratio, health conditions, and so on.
Age
In principle, age does not affect the IBW of girls who are more than 14-15 years old or boys who passed the stage of 16-17, as most physical development stops after such stages. However, when people get old, there will be a decrease in lean mass muscle and an increase in fat mass. Furthermore, both males and females are said to respectively get a loss of 1.5 inches and 2 inches in height when reaching the age of 70.
Though we can reduce the above-mentioned impacts partly via persistently practicing good habits such as doing morning exercises, having good diets, or getting enough sleep…, we cannot eliminate the aging process. So, age is one of the factors considered when computing the ideal body weight.
Determining your ideal weight depends on various factors such as gender, height, age, and body type. As your age changes, your body composition and metabolism also change. Therefore, it’s essential to find your ideal weight concerning your age. 11-year-old boys and girls may have different ideal weights depending on their height and body type as compared to adults.
Gender
Due to several different characteristics in the body of males and females, gender becomes a determinant of IBW. Firstly, it’s the matter of muscle mass and bone density, which is usually higher in males. Clearly, muscle and bone are heavy and heavier than body fat that is said to be at a higher rate in females. Secondly, males are generally taller in comparison with females. Thus, there will be differences in the ideal weight of males and females.
Height
Taller persons will have more muscle mass and body fat, which will make them gain more weight. Thus, obviously, height affects the ideal body weight measurement.
Accurately determine your height in centimeters, meters, feet, and inches with this height calculator. Need to convert your height from feet and inches to centimeters? No problem, we’ve got you covered. Simply use our feet-to-cm converter and never worry about miscalculating your height again.
Body Fat
Body fat is the amount of fat tissue in your body. You need body fat, but too much can be unhealthy, especially around your waist. To find out about your body fat percentage and risk of disease, you can speak with a healthcare provider or complete the following body fat calculator.
Body Frame Size
Besides the above-mentioned elements, body frame size is also an element having a notable influence on the ideal weight. The body frame size normally includes three types: small-boned, medium-boned, and large-boned, which are classified based on the wrist size of a person for each group of height. The following table shows you the classification of the body frame size.
| Height | Male | Female |
| Under 5’2’’ | Small-boned = wrist size less than 5.5″ | |
| Medium-boned = wrist size 5.5″ to 5.75″ | ||
| Large-boned = wrist size over 5.75″ | ||
| Between 5’2’’ and 5’5’’ | Small-boned = wrist size less than 6″ | |
| Medium-boned = wrist size 6″ to 6.25″ | ||
| Large-boned = wrist size over 6.25″ | ||
| Over 5’5’’ | Small-boned = wrist size 5.5″ to 6.5″ | Small-boned = wrist size less than 6.25″ |
| Medium-boned = wrist size 6.5″ to 7.5″ | Medium-boned = wrist size 6.25″ to 6.5″ | |
| Large-boned = wrist size over 7.5″ | Large-boned = wrist size over 6.5″ |
The weight of someone who is large-boned is usually more than someone who is small-boned, as the bone, even when both people are the same height. Thus, body frame size will have certain impacts on IBW.
How Much Should I Weigh?
Calculating Your Healthy Body Mass Index (BMI) by using BMI Calculator.
Calculating your BMI is an easy process, and most of you will already know what it is. You just need to know your weight in kilograms and height in centimeters, as well as the base number for a healthy BMI range (18.5 – 24.9).
Body Mass Index or BMI measures fatness because it shows how much you weigh in relation to your height. BMI is a number calculated from your body weight and height that is used as an indicator of health. It is only a rough guide because it does not take into account such factors as how much muscle you have, but it is helpful for classifying whether you are a healthy weight for your height (e.g. underweight, normal, overweight, or obese).
BMI is calculated from the following formula:
Where:
W = weight in kilograms (kg)
H = Height in centimeters (cm)
BMI = Body Mass Index, a number between 18.5 and 24.9.
Note: If your height is not known, calculate your BMI using this chart. However, if you are under 18 years old, or have a BMI less than 15.0, you will not be able to calculate your BMI.
Healthy BMI range: 18.5 – 24.9
Normal weight (BMI 18.5-24.9):
Overweight (BMI 25-27.9):
Obese (BMI 27.9-34.9):
Morbidly obese (BMI > 35)
For example, a 20-year-old man with a height of 170cm and a mass of 80kg is within the healthy weight range for his height and age. His BMI is 22.7, which is in the ‘overweight’ category according to the table above. He should aim to reach an ideal body weight of 76kg (in kilograms) within two years.
Army Ideal Weight
Depending on the number of people who are joining the army and their weight, it is currently between 140 and 170 pounds. However, the number of soldiers is increasing and this is a problem because the army has to be able to accommodate all these people. The way that the army is able to do this is by calculating how many soldiers they have. By knowing how many people are joining, they can calculate their ideal weight. This calculator will allow them to do just that.
The Army Body Fat Calculator allows you to input your height, age, and weight in pounds then it will tell you what your ideal body weight should be for your height.
Formulas for calculating the ideal weight
At the first stage of its appearance, IBW formulas were created for medical purposes. In particular, they were intended to be the tool for setting drug doses suitable to the patients’ weight and height.
In general, all the equations will start with a fixed weight for the height of five feet, then add another number for each inch over five feet. Each equation will be a little different between male and female as gender is one of the factors that were considered as mentioned above.
For detailed information, you can check out the table below.
| Formulas | Male | Female |
| G. J. Hamwi Formula (1964) | 48.0 kg + 2.7 kg per inch over 5 feet | 45.5 kg + 2.2 kg per inch over 5 feet |
| B. J. Devine Formula (1974) | 50.0 kg + 2.3 kg per inch over 5 feet | 45.5 kg + 2.3 kg per inch over 5 feet |
| J. D. Robinson Formula (1983) | 52 kg + 1.9 kg per inch over 5 feet | 49 kg + 1.7 kg per inch over 5 feet |
| D. R. Miller Formula (1983) | 56.2 kg + 1.41 kg per inch over 5 feet | 53.1 kg + 1.36 kg per inch over 5 feet |
The Devine Formula, which is the most commonly used formula for calculating IBW these days, was initially introduced by Dr. B. J. Devine in 1974 for estimating the most appropriate medicinal doses. Similarly, Hamwi Formula was invented by Dr. G. J. Hamwi in 1964 for the same purposes. Besides, Robinson Formula and Miller Formula were improved from Devine Formula and published in 1983.
As you may observe, the formulas are quite similar in format, just different in the values for calculation. Such difference results from specific research and findings that the experts participated in while developing the formulas.
With our Ideal Weight Calculator, you can check the results of all formulas in a comparative view. Just enter the units, and you will see the four results for your reference.
Ideal Weight for Men
Ideal weight for men is calculated by factoring in the height of the person using this formula:
Ideal Weight = (6 x Height) + (12.7 x Weight) – (6.25 x Age) + 5
The result of this calculation must be rounded down to the nearest pound. For example, if a man were 5 feet tall and weighed 95 pounds, his ideal weight would be approximately 90 pounds; 78 pounds would be an overestimation of his ideal weight.
Ideal Weight for Women
To calculate a woman’s ideal weight, the formula is:
Ideal Weight = (4.6 x Height) + (12.7 x Weight) – (3.66 x Age) + 5
The result of this calculation must be rounded down to the nearest pound. For example, if a woman were 5 feet tall and weighed 90 pounds, her ideal weight would be approximately 78 pounds; 97 pounds would be an overestimation of her ideal weight.
Healthy Weight Range Based on BMI
BMI (Body Mass Index) shows somebody’s weight (kilograms) in each square of height (meters). BMI is also a popular way to find out the IBW. The following chart is standard BMI indicators together with respective weight status for adults.
| Weight status | BMI |
| Underweight | less than 18.5 |
| Normal weight | 18.5 – 24.9 |
| Overweight | 25 – 29.9 |
| Obesity | 30 – 35 |
| Severe obesity | 35 and more |
The BMI indicators of from 18.5 to 24.9 is the healthy range suggested by the World Health Organization (WHO) for all adult people regardless of gender. Optimal weight can also be calculated based on the BMI range. BMI is very popular in the medical field as it is a common indicator used for showing health status in a quick way. It reflects the chances of encountering obesity, diabetes, heart disease, etc. Periodic checks of your BMI, like periodic health examination, help to evaluate your health status and prevent risks of getting diseases.
For children and teens, the formula of BMI is a little different as age and gender will be taken into consideration. At such stages, the body fat differs between girls and boys and depends on the age as well. The Centers for Disease Control and Prevention (CDC) recommend a BMI from 5th to less than 85th percentile for children depending on their specific age.
| Weight status | BMI |
| Underweight | less than 5th percentile |
| Normal weight | 5th percentile to less than 85th percentile |
| Overweight | 85th percentile to less than 95th percentile |
| Obesity | equal to or greater than 95th percentile |
Besides giving you four results of IBW based on four different formulas, our Ideal Weight Calculator also provides you with BMI indicators. The BMI result will be expressed in a weight range instead of a number like the ones of four formulas.
In other words, our Ideal Weight Calculator transfers the normal BMI indicators to weight indicators, showing you the range of suitable weights for your height.
Measure your waist-to-hip ratio to calculate ideal weight
Use a soft or hard measuring tape measure around the widest part of your hips and waist. Round your hip measurement to the nearest ½ inch. For example, if your measurement is 35¾ inches, round it to 36 inches. If your waist is larger than 35 percent of your height, subtract 5 pounds for every inch over 35%. For example, if you are 5`4″ tall and have a 37-inch waist, subtract 5 pounds (for a total of 10 pounds) from the weight at which you would have a healthy waist-to-hip ratio.
Measure your hip to waist and weight to calculate ideal weight:
The formula used to calculate a healthy ideal weight is BW = (H2W)/2(H2W).
Example:
- Height: 5’4″
- Weight: 175 lbs.
- Waist to hip ratio = 31.25%
- Healthy ideal weight = 202 lbs. (5’4″ /2.25″ = 202).
NOTE: You will not be able to meet the current ACSM guidelines if you currently weigh more than 242 pounds and possess a waist to hip ratio of 36%.
The formula used to calculate an unhealthy ideal weight is BW = (H2W)/2(H2W+D). In the U.S., overweight is considered anything greater than 25 percent of one’s ideal body weight. An unhealthy ideal range varies, depending on age, gender, ethnic heritage and other factors.
Waist-to-height Ratio Method to calculate ideal weight
A waist-to-height ratio is one of the best measurements to determine if a person is overweight or not. It uses the circumference of your waist and the height of your inseam, which are measured around your hips. The formula for this ratio is 100 divided by your height in inches. People with a waist-to-height ratio within the normal range from 98.9 – 102.1
A waist-to-height ratio over 100 is a probable indicator that the patient is overweight and may be at risk for various diseases related to excess weight, such as heart disease, diabetes, certain cancers, and osteoporosis.[23]
The waist-to-height ratio method formula is 100 divided by your height in inches.
People with a waist-to-height ratio within the normal range from 98.9 – 102.1
A waist-to-height ratio over 100 is a probable indicator that the patient is overweight and may be at risk for various diseases related to excess weight, such as heart disease, diabetes, certain cancers, and osteoporosis.
Example:
- Height in inches: 177
- Waist circumference: 28.5 inches (measured in cm)
- waist-to-height ratio = 100/177= .29 or 29%
skinfold and anthropometric measurements – the waist-to-height ratio
The waist-to-height ratio has been widely used as a measure of obesity. In recent years, many variations of this method have come into use. One such method was devised by Winthrop and Syme. This method was based on the idea of obtaining an accurate waist measurement by using a tape measure and therefore minimizing the influence of body fat on the final measurement. The adjusted waist-to-height ratio is estimated by determining the somatotype classification and applying a correction factor.
Ideal Waist Size for Women
The current reference range is between 23.8 and 34.9 inches for women and between 24.0 and 36.4 inches for men, with the average weight being approximately 15% heavier than the reference ranges.[29] The measurement by waist-to-height ratio, as described above, is also used to assess whether a person has obesity.
Men and women in good health should have a waist-to-height ratio of 0.7 or less; those with chronic diseases of obesity (e.g. diabetes, and hypertension), should have a ratio of 0.5 or less. Those at risk for colon cancer should have a ratio of less than 0.5 and those at risk for cardiovascular disease a ratio of less than 0.4.[33]
Ideal Waist Size for Men
The reference ranges for waist circumference measurements for men are less well established than for women. The current recommended range is 102 to 144 cm (40.0 to 56.7 in) for men and 88 to 117 cm (34.6 to 46.7 in) for women.
Usually, goals are set using a percentage of fat instead of absolute height and weight measurements. For example, a goal may be set where an individual has their waist circumference reduced by 30% from their starting point.
To determine your ideal waist size, it’s important to first measure your waist properly. Follow this guide on how to measure your waist for accurate results. Once you have your waist size, you can use this information to find the perfect pair of jeans using our jeans size chart for men.
Advantages and disadvantages of our Ideal Weight Calculator
As a measurement tool, our Ideal Weight Calculator will have both pros and cons in its functions. You can see the details below.

Incline walking is a great way to get some extra benefits from your workout. It requires less impact force on your joints while still working the same muscles as regular walking. You can burn more calories and work your cardiovascular system more efficiently. Learn more about the benefits of incline walking by checking out our article here.
Disadvantages
The limitations of the ideal weight calculator coming from the limitations of formulas and methods. As they are created to serve many people, we cannot ask for an accuracy rate of individual-to-individual from them.
The formulas do not take into account the matter of muscle mass, body fat, or bone density. It can also be not really accurate for someone who is pregnant or having physical handicaps. Thus, take our Ideal Weight Calculator as a general tool for computing healthy weight based on popular formulas, do not consider its results as something must to chase in any way.
