# What Is The Purpose of A Height-Weight Calculator?

The Ideal Weight Calculator calculates the ideal body weight (IBW), based on height, gender, age, and other factors. Experts have long sought out the idea of finding the IBW by using a formula. There are many popular formulas out there, and our Ideal Weight Calculator gives their results so you can compare them side-by-side.

**What Should I Weigh?**

Nearly everyone has tried to lose weight at one time or another. This is due to our perception of ideal body weight. It is often based upon what we see on TV, in movies, and in magazines. While ideal body weight (IBW)is often based on visual appeal, it was originally introduced to help determine dosages for medical purposes. The formulas used to calculate it do not depend on how someone looks at a given weight. Since then, it has been shown that certain drugs’ metabolism is more dependent on IBW than total body weight. IBW is widely used in sports today, as many sports categorize people according to their body weight.

The IBW is not an exact measurement. It doesn’t take into account body fat or muscle percentages. It is possible for fit and healthy athletes to be overweight based upon their IBW. It is important to remember that IBW is an imperfect measurement and should not be regarded as a determinant of health or a goal that one should strive for. It is possible to be above or below your “IBW” while still being perfectly healthy.

It is difficult to determine how much an individual should weigh. Each person is the best judge of how much they should weigh. There is no single measure that can determine how much someone should weigh to be healthy, whether it’s IBW or body mass index (BMI), and there are none. These are just references. It’s much more important to make healthy lifestyle choices like regular exercise, eating unprocessed food, adequate sleep, and making good dietary choices. It is easier to achieve a particular weight by following a generalized approach than to try and maintain it.

However, there are many factors that can influence the ideal weight. The main factors are listed below. Others include health conditions, fat distribution, and progeny.

**Age**

Age shouldn’t play a significant role in determining an IBW beyond the age of 14-15 for girls, and 16-17 for boys. After that, most people stop growing. Human males and women will lose 1.5 inches and 2 inches respectively between the ages of 14-15 and 16-17. It is important that you remember that the lean muscle mass of people as they age decreases, making it easier to build up excess body fat. It is normal, but it is possible to slow down the effects of aging through healthy habits like exercise and diet.

**Gender**

Females are generally lighter than males, despite having a higher body fat percentage. This is because males have more muscle mass and fat is heavier than muscle. Women have lower bone density, and this is not the only reason. Last, but not least: Males are generally taller than their female counterparts.

**Height**

A person who is taller will have more muscle mass and body weight, which leads to more weight. A male of the same height Calculator as a woman should be 10-20% more heavy.

Size of the Body Frame

The measurement of your ideal weight can also be affected by the size of your body frame. The body frame is usually classified as either small, medium, or large-boned. The measurement is based on the circumference and height of a person’s wrist.

For women:

- Height under 5’2″
- Small bones = wrist size below 5.5 inches
- Medium Boned = wrist size between 5.5″ and 5.75″
- Large bones = wrists larger than 5.75″

- Height range between 5’2″ to 5′ 5″
- Small bones = wrist size below 6 inches
- Medium Boned = wrist size 6-8″ to 6.25″
- Large bones = wrists larger than 6.25″

- Height greater than 5′ 5″
- Small bones = wrists smaller than 6.25″
- Medium Boned = wrist size between 6.25″ and 6.5″.
- Large bones = wrists larger than 6.5″.

For men:

- Height greater than 5′ 5″
- Small bones = wrist size between 5.5″ and 6.5″.
- Medium Boned = wrist size somewhere in the range of 6.5″ and 7.5″.
- Large bones = wrists larger than 7.5″.

Larger bones will naturally make a person weigh more than someone with smaller bones, even if they are the same height. This can impact measurements like IBW or BMI.

**Formulae for Finding Your Ideal Weight**

IBW formulas were created to simplify drug dosage calculations. The formulas all have the same structure: a base weight given that you are 5’10” tall, and a weight increment per inch above that. If you’re a male of 5’10”, and you want to estimate your ideal weight using the Devine formula, then you would multiply (2.3×10) kg to 50kg to get 73kg or 161 lbs.

Based on the results of their research and the findings of their scientists, the formulas have different values. The most commonly used formula to measure IBW is the Devine formula.

**G. J. Hamwi Formula (1964).**

Male | 48.0 kg + 27.5 kg per inch for every 5 feet |

Female | 45.5kg + 2.2kg per inch above 5 feet |

Invented for medicinal dosage purposes.

**B. J. Devine Formula (1974).**

Male | 50.0 kg + 2.3kg per inch above 5 feet |

Female | 45.5kg + 2.3kg per inch above 5 feet |

It was similar to the Hamwi Formula. It was initially intended to be a basis for medical dosages based upon weight and height. The formula was eventually adopted as a universal determinant for IBW.

**J. D. Robinson Formula (1983).**

Male | 52 kg + 1.9kg per inch above 5 feet |

Female | 49 kg + 1.7kg per inch above 5 feet |

Modification of Devine Formula

**D. R. Miller Formula (1983).**

Male | 56.2kg + 1.41kg per inch above 5 feet |

Female | 5.3.1kg + 1.36kg per inch above 5 feet |

Modification of Devine Formula

**Healthy BMI range**

For both males as well as females, the recommended healthy BMI range of the World Health Organization (WHO), is 18.5 to 25. It is possible to determine a healthy weight for any height using the BMI range.

For calculating IBW, BMI is a common metric. It is commonly used in medical fields to indicate possible health problems. The BMI is a measure of how likely someone is to develop health problems like diabetes, obesity, heart disease, or other conditions. Doctors use it to warn patients about potential health problems. It is used to classify individuals according to their obesity level.

Sound BMI range for youngsters

All formulas are intended for adults over 18. The following BMI charts were created by the Centers for Disease Control and Prevention. Based on age, the CDC recommends children keep their BMI between the 5th and 85th percentile.

**What’s the problem with BMI?**

The BMI measurement is very simple. Although it considers height, it doesn’t account for other factors like:

- Measurements of the hips or waist
- Fat distribution and proportion
- Proportion of muscle mass

They can also have an effect on your health.

For example, high-performance athletes tend to be extremely fit and have very little body fat. A high BMI is not necessarily a sign that they are overweight.

The BMI can be used to determine if a person is healthy or unhealthy. It is also useful in determining trends in population studies.
