## First of all, know that there is no ideal weight strictly speaking, and that being in good health is the most important thing! Apart from the body mass index (BMI), the only indicator validated by the World Health Organization (WHO) to calculate a person’s corpulence, other methods allow evaluating a person’s ideal weight, taking into account several variables, including height and age, among others.

So how do you calculate your ideal weight based on these two indicators? Here is the method, in detail.

If you want **know your ideal weight according to**** your height and age, we recommend that you use** **Cref formula.**

In fact, this method makes it possible to improve the Lorentz formula which, for its part, only takes into account the person’s height and gender.

Developed in the seventies, **Creff’s formula proved to be more ****demanding than the other formulas**, with the only condition: pay close attention to its morphology. According to this formula, the ideal weight is calculated based on 3 parameters: morphology, height in centimeters and age.

The formulas are as follows:

- For a person with a so-called “normal” morphology:
**Ideal weight (in kg) = Height (in cm) – 100 + (Age (in years) /10) x 0.9** - For a person with a so-called “wide” morphology:
**Ideal weight (in kg) = Height (in cm) – 100 + (Age (in years) /10) x 0.9 x 1.1** - For a person with a so-called “graceful” morphology:
**Ideal weight (in kg) = Height (in cm) – 100 + (Age (in years) /10) x 0.9 x 0.9**

From then on, you just have to choose the formula that best suits your morphology to determine your ideal weight.

## Calculation of the ideal weight: Creff’s formula, disadvantageous despite everything?

While this formula is accurate enough to calculate your ideal weight, it does have some drawbacks: for example, **the beginning of this formula ****a**** based on the distinction between normal, large and slender people**. These concepts are quite vague and subjective. In addition, it does not take into account the differences that exist between the two sexes. Therefore, it may seem somewhat approximate.

## Other formulas to calculate your ideal weight

As mentioned above, there are many methods, in addition to Creff’s formula, to calculate the ideal weight, where other parameters are taken into account. Let’s find out!

**Drill formula:**Invented by the French surgeon Dr. Paul Broca, this formula is considered the oldest and allows you to calculate the ideal weight as follows:**Height (in cm) – 100 = ideal weight (in kg).****Bornhardt formula:**Dating back to 1891, this formula was designed to determine the corpulence of people involved in the military in order to ensure their physical fitness for military service. The formula remains more reliable than Broca’s as it takes into account the individual’s silhouette. The calculation is done in this way.**: Ideal weight (in kg) = ((Height (in cm) x Chest circumference (in cm)) / 240.****divine formula:**This formula was developed by Dr. BJ Devine in 1974, knowing that it was originally intended to calculate the dose of certain medicinal substances. According to the latter, the calculation of the ideal weight is carried out as follows (representing the thumb approximately 2.5 centimeters):**Male ideal weight (in kg) = 50 (kg) + 2.3 x [Taille (en pouces*****) – 60].****Ideal female weight (in kg) = 45.5 (kg) + 2.3 x [Taille (en pouces*****) – 60].**

As you can see, there are different ways and ways to calculate your ideal weight. However, keep in mind that a balanced diet and regular physical activity are essential to maintain a healthy weight.
