Ideal Weight Calculator

Maintaining a healthy weight is important for overall health and well-being.


Use our Ideal Weight Calculator to find out your target weight based on your

age, height, and gender.


Achieving a healthy weight can help prevent chronic diseases, boost energy levels, and improve self-esteem.

Determining Optimal Weight

Many individuals have, at some point, aimed to shed excess weight or have encountered someone on such a quest.


This pursuit is often driven by the notion of an "ideal" body weight, frequently influenced by societal ideals perpetuated through media channels like social media, TV, movies, and magazines.


Initially introduced to estimate medical dosages, Ideal Body Weight (IBW) has evolved to play a role in various domains, including sports classifications based on body weight.

It is crucial to acknowledge that IBW, rooted in medical utility, does not factor in body composition—specifically, the percentage of body fat and muscle. Highly fit athletes may be deemed overweight based on IBW due to increased muscle mass.


Therefore, it is imperative to view IBW as an imperfect measure, not necessarily indicative of health. Being over or under the calculated "IBW" does not necessarily correlate with optimal health.

Determining an individual's ideal weight is far from an exact science. It varies greatly from person to person, and no measure, including IBW, Body Mass Index (BMI), or others, can definitively specify an ideal weight for health.


Rather than fixating on a specific weight derived from a generalized formula, emphasis should be placed on cultivating healthy lifestyle habits, such as regular exercise, a balanced diet, sufficient sleep, etc.

Several factors influence the ideal weight, with key determinants outlined below, alongside other considerations like health conditions, fat distribution, and genetics.

  • Age: Age becomes less influential in determining IBW after adolescence. Aging leads to a natural decline in lean muscle mass, making it easier to accumulate excess body fat. Mitigating this effect involves adopting habits such as monitoring diet, exercise, stress, and sleep.

  • Gender: Generally, females weigh less than males, despite having a higher percentage of body fat. This is attributed to the typically higher muscle mass in males, as muscle is denser than fat. Additionally, men tend to be taller.

  • Height: Taller individuals typically have more muscle mass and body fat, resulting in increased weight. For similar heights, males should weigh about 10-20% more than females.

  • Body Frame Size: Categorized as small, medium, or large boned, body frame size is determined by the circumference of the wrist in relation to height. Larger boned individuals naturally weigh more than their smaller boned counterparts, even at the same height.

Formulas for Ideal Weight: IBW formulas, initially designed for drug dosage calculations, have the same structure: a base weight for a height of 5 feet with a set weight increment per inch beyond 5 feet.


Common formulas include:

  • G. J. Hamwi Formula (1964)

  • B. J. Devine Formula (1974)

  • J. D. Robinson Formula (1983)

  • D. R. Miller Formula (1983)

Healthy BMI Range: The World Health Organization recommends a healthy BMI range of 18.5 - 25 for both males and females. BMI serves as a quick indicator of potential health risks, with higher values correlating with increased chances of conditions like obesity, diabetes, and heart disease.

Limitations of IBW Calculator: While these formulas offer general guidelines, they cannot account for individual variations, such as physical handicaps, extreme cases, activity levels, or body composition. Our Ideal Weight Calculator serves as a broad reference based on popular formulas and is not intended as a strict mandate for achieving an "ideal weight."
