Maintaining a healthy body weight is one of the key factors for overall health and well-being. But how do you know what weight is ideal for your body? That’s where an Ideal Body Weight (IBW) Calculator comes in handy. This tool helps estimate the weight range that is considered healthy based on your height, sex, and age.

What is Ideal Body Weight?
Ideal Body Weight is an estimate of what a healthy weight should be for your body type. It’s not a strict rule but rather a guideline to help you understand your body composition and maintain good health. Factors like age, gender, height, and muscle mass can influence your ideal weight.
Several commonly used formulas estimate IBW:
Devine Formula (1974): One of the most popular formulas used in medicine.
Hamwi Formula (1964): Focuses on body frame and gender.
Robinson Formula (1983): Provides slightly lower estimates than Devine.
Miller Formula (1983): Offers an alternative approach for different body types.
How to Use the Ideal Body Weight Calculator?
Using our Ideal Body Weight Calculator is simple:
- Select your preferred measurement system: Metric (cm) or Imperial (ft/in).
- Enter your height and age.
- Choose your gender.
- Click Calculate to see your ideal weight range according to the Devine, Hamwi, Robinson, and Miller formulas.
The calculator also converts the results into pounds for convenience. Remember, these are estimated values — factors like body composition, lifestyle, and health conditions can affect your ideal weight.
How Much Should I Weigh? Understanding Your Ideal Body Weight
Most people have wondered at some point, “How much should I weigh?” or know someone who has tried to reach a perceived “ideal” weight. This concept of an ideal body weight (IBW) is often influenced by images in media, including social media, television, movies, and magazines. However, the original purpose of IBW was not about appearance—it was developed to estimate dosages for certain medications. Studies have shown that the metabolism of many drugs is more closely related to IBW than total body weight.
Today, IBW is also used in sports, particularly in disciplines where athletes are classified by weight. Despite its usefulness, it is important to note that IBW is not a perfect measure. It does not account for the percentage of body fat, muscle mass, or bone density. Highly fit individuals may be classified as “overweight” according to IBW formulas even though they are perfectly healthy. Therefore, IBW should be considered a guideline rather than a strict target.
No measure, including IBW or Body Mass Index (BMI), can definitively determine the “perfect” weight for an individual. Weight is highly personal, and healthy lifestyle choices—such as regular exercise, balanced nutrition, sufficient sleep, and stress management—are far more important than chasing a specific number on the scale.
Factors Affecting Ideal Body Weight
Age:
Age plays a role in weight management, especially as we grow older. After the typical growth period—around 14-15 years for girls and 16-17 years for boys—height generally stabilizes. By age 70, most adults lose approximately 1.5 inches (males) or 2 inches (females) in height. With aging, lean muscle mass tends to decrease while body fat can increase. This is a natural process, but maintaining healthy habits—such as regular exercise, a balanced diet, stress management, and sufficient sleep—can help minimize these effects.
Height:
Height directly affects weight. Taller individuals typically carry more muscle and body fat, which increases their weight. For example, a male of a similar height to a female will usually weigh about 10–20% more.
Body Frame Size:
Body frame size can significantly influence ideal weight. Frame size is generally categorized as small, medium, or large, and is often measured using wrist circumference relative to height.
For Women:
Height under 5’2”:
Small: wrist < 5.5”
Medium: wrist 5.5–5.75”
Large: wrist > 5.75”
Height 5’2”–5’5”:
Small: wrist < 6”
Medium: wrist 6–6.25”
Large: wrist > 6.25”
Height over 5’5”:
Small: wrist < 6.25”
Medium: wrist 6.25–6.5”
Large: wrist > 6.5”
For Men:
Height over 5’5”:
Small: wrist 5.5–6.5”
Medium: wrist 6.5–7.5”
Large: wrist > 7.5”
Formulas for Finding the Ideal Weight
For example, if you are a 5’10” male estimating your ideal weight using the Devine Formula, you would add (2.3 × 10) kg to 50 kg to get 73 kg, or approximately 161 lbs.
The formulas differ based on the research and findings of the scientists who developed them. Among these, the Devine Formula remains the most widely used method for calculating IBW in both medical and health contexts.
- 1. G. J. Hamwi Formula (1964)
- Male: 48.0 kg + 2.7 kg per inch over 5 feet
Female: 45.5 kg + 2.2 kg per inch over 5 feet
Originally developed for medicinal dosage purposes. - 2. B. J. Devine Formula (1974)
- Male: 50.0 kg + 2.3 kg per inch over 5 feet
Female: 45.5 kg + 2.3 kg per inch over 5 feet
Similar to the Hamwi Formula, it was initially designed for medical dosage guidance but later became a standard method for estimating ideal body weight. - 3. J. D. Robinson Formula (1983)
- Male: 52.0 kg + 1.9 kg per inch over 5 feet
Female: 49.0 kg + 1.7 kg per inch over 5 feet
A modification of the Devine Formula aimed at refining weight estimation accuracy. - 4. D. R. Miller Formula (1983)
- Male: 56.2 kg + 1.41 kg per inch over 5 feet
Female: 53.1 kg + 1.36 kg per inch over 5 feet
