What is the ideal weight for a woman of 1m70?

According to a 2020 study(1), 2 out of 3 women admit to being complexed by their body. The media (advertisements, television, social networks) would particularly reinforce their malaise. The first complex is of course the weight which is, especially among French women, never low enough. But what is the ideal weight of a woman measuring 1m70? Some answers…

How to calculate the ideal weight of a woman of 1m70?

The ideal weight corresponds tothe corpulence considered average in a given society. The World Health Organization defines this body size from a number, the Body Mass Index (BMI). It is considerednormal when the BMI is between 18.5 and 25 kg per square meterfor an adult population aged 18 to 65 years. The normal BMI varies significantly forolder people (it should be between 21 and 25) and top athletes (normal BMI between 26 and 28). Finally, BMI is calculated as follows: Weight (kg) / Height (m)2. There are calculators to facilitate this calculation, likehere.

However, there areother calculation methods to define the ideal weight. Indeed, BMI is an imperfect formula, which does not take into accountthe natural morphologyof a person, the state of his musculature or his ethnic origin. In addition, it does not apply to children. Other formulas have therefore been developed to try to correct these biases.

What are the results of the calculation formulas for a woman of 1m70?

Ceff’s formula

The formula of Creff takes into account the criterion of the natural silhouettetag. It is calculated as follows:
Ideal weight (kg) = Height (cm) – 100 + k 9/100 age (years), where k = 0.9, 1 and 1.1, depending on whether you have a Slim, medium or wide body type. To simplify this calculation, you can useour calculator .

What is the ideal weight of a woman of 1m70 with this formula? Everything will depend on the age andmorphology of the woman in questiontag. Thereby :

  • a woman of 20 years and 1m70 should weigh 58.32 kg kg, , if she has a slender figure, silhouette, 64.8 kg kg for a normal silhouette, 71.28 kg for a stocky figure;
  • a kg,silhouette,kg for a normal silhouette,a woman aged 40 and 1m70 should weigh 59.94 kg , if she has a slender figure,66.6 kg 73.3 kgfor a large figure;
  • a woman aged 60 and 1m70 should weigh 61.56 kg kg, , if she has a slender figure, silhouette, 68.4 kg kg for a normal silhouette, 75.2 kg for a more massive figure.

Formula de Broca

This is a very simple calculation method, but not necessarily very exact or relevant. It is only based onthe size of an individual , without distinction of gendertag. It does not take into account age, morphology, or other criteria that may be relevant in estimating an ideal weight. It corresponds to: Ideal weight (kg) = Height (cm) – 100. Again, you can find an automatic calculatorhere .

Regarding the ideal weight of a woman of 1m70, it is invariable according to age, since it is not taken into account in the calculation. And it is 70 kg . 

Formula de Lorentz

This calculation method is widely used because it takes into account the Morphological differences between men and womentag. For men, it is used as follows: Ideal weight (kg) = Height (cm) – 100 – ((Height (cm) – 150)/4). For women, the calculation is as follows: Ideal weight (kg) = Height (cm) – 100 – ((Height (cm) – 150)/2.5). To simplify your calculation process, it’shere .

What does the formula give for our 1m70 woman? His ideal weight is65 kg .

Monnerot-Dumaine formula

Here’s another formula that attempts to take body shape into consideration, based on joint thicknesstag. Thus, an unusual fact, it is based on the measurement of the circumference of the wrist. It is calculated as follows: Ideal weight (kg) = Height (cm) – 100 + (4 x Wrist circumference (cm)/2. The automatic calculator ishere .

The Monnerot-Dumaine formula is difficult to apply to our example. However, we can say that:

  • A petite woman has an average wrist circumference of 14 cm. If she measures 1m70, her ideal weight is63 kg  ;
  • a “normal” woman has an average wrist circumference of 16 cm, her ideal weight is therefore67 kg  ;
  • a corpulent woman has an average wrist circumference of 18 cm, so her ideal weight is 71 kg .

Formulas of Devine

A slightly more unusual calculation, very popular in Anglo-Saxon countries. Originally this formula was weighted for care purposes, since it was used to adjust the doses of medicinal substances according to the weight of the patient concerned. It is now used to estimate the ideal weight, and is calculated as follows, according to sex:

  • Male ideal weight (kg) = 50 + 2.3 x (Height (inches) – 60)
  • Ideal female weight (kg) = 45.5 + 2.3 x (Height (inches) – 60)

For information, an inch corresponds to approximately 2.54 cm. To use this formula simply, gohere .

According to this formula, the ideal weight of a woman is 61.44 kg

Peck’s formula

Here is another calculation method of Anglo-Saxon origin, which is calculated from the height in inches. It is interesting because it differs significantly according to age (child and adult distinction) and sex. It is calculated as follows:

  • Male Ideal Weight (kg) = -130.736 + (4.064 x Height (inches))
  • Female ideal weight (kg) = -111.621 + (3.636 x Height (inches))

It is quite tedious, so you can use our calculator .

The latter gives us, for a woman of 1m70, an invariable result (age not being taken into account) of 59.75 kg

Bornhardt’s Formula

A final method of calculating the ideal weight, which proposes to take into account the Chest circumferencetag. It therefore takes into account, like the Monnerot-Dumaine formula, a morphological characteristic. It is used as follows: Ideal weight (kg) = (Height (cm) x chest circumference (cm)) / 240. The site again offers an automatic calculatorhere .

 According to Bornhardt’s formula, the ideal weight of a woman of 1m70 depends on her chest circumference. For example:

  • a woman of 1m70, with a Chest circumference of 85 cm, should weigh 60.21 kg  ;
  • his ideal weight is 63.75 kg if his chest circumference is 90 cm;
  • Finally, it should ideally display a weight of67.3 kgin the case of a chest circumference of 95 cm.

Finally, according to the BMI calculation: the ideal weight should be between 55.5 kg and 72 kg.

In view of these results, one thing seems clear: the ideal weight for a woman of 1m70 varies significantly, oscillating between 55.5 kg (lowest BMI) and 75 kg (Creff formula for a 60-year-old woman with a wide silhouette). This is far from the usual goals of women, who all too often aspire to a weight below health recommendations or theirhealthy weight.
