BMI Calculator

Calculate

 

The Body Mass Index is used to determine whether a person is overweight or is at a normal weight. The BMI calculator for women is used significantly more often than the one for men. The reason for this is the comparably more health-conscious attitude held by women. However, despite this, many women suffer from various health problems due to being overweight.

Body Mass Index (BMI) is not just used with reference to the topic of health. In some cases, women base the weight they are most happy at on their BMI. On one hand, you can use this index as an indicator for a healthy body weight. On the other hand, the value can also be used for diets or other weight loss programmes, such as exercise, in order to portray progress. With the BMI calculator for women, these developments can be easily documented as long as BMI is re-calculated regularly.

Body Mass Index for women

For women, bodyweight is often an ever-present topic. Body Mass Index is often applied by women in order to determine whether their own bodyweight is considered healthy or unhealthy in relation to their height. BMI can be easily calculated by any woman using a simple formula. This formula only takes into account two factors, the “height” and “weight” of a woman, and is therefore easy to apply. It is even more easy to use the BMI calculator for women on this website. The result of this calculation can be easily interpreted using defined classifications. The WHO, the World Health Organisation, subdivides BMI into several classes which range from underweight to severely obese. These classes can be viewed in the following table.

BMI Table

Classification BMI
Underweight < 18,5
Normal weight 18,5 – 24,9
Overweight 25 – 29,9
Obese class I 30 – 34,9
Obese class II 35 – 39,9
Obese class III > 40

Underweight according to the BMI calculation:

If the BMI calculated for a woman is below 18.5 kg/m², this is considered underweight. If you are close to reaching this limit, do not panic. If, however, your BMI is significantly below 18.5 kg/m², countermeasures must be taken. A bodyweight that is too low is often linked with health risks. At a BMI below 18.5kg/m², your body is lacking the necessary fuel to remain healthy. Furthermore, important functions, such as the formation of enzymes or hormones, can be restricted. In the event of a clear classification in the underweight category, your recent diet should be reviewed and the supply of energy or calories should be increased. If the BMI of a women is very far below 18.5 kg/m², it is important to seek medical help.

Normal weight according to the BMI calculation

If the BMI calculator for women reveals a value between 18.5 kg/m² and 24.9 kg/m², bodyweight is considered in the normal range. Classification of BMI in this range is thus also considered normal weight. Many women who are actively trying to reach their personal ideal or healthy weight should aim for a value within this range.

Detecting if a woman is overweight using the BMI:

All women would like to avoid being classified as overweight or above according to their BMI. Being overweight is when the BMI calculator gives a value between 25 kg/m² and 29.9 kg/m². Being slightly overweight is not always a bad thing. There are studies which say that the life expectancy of people who have been classed as overweight according to their BMI is statistically the longest. Regardless, women should take care that their BMI does not get out of hand and rise too high. One thing is for sure: Being too overweight is definitely bad for the health and brings its own risks.

Obesity – Critical BMI values for women:

A more precarious situation is when your Body Mass Index is 30 kg/m² or above. This value and above is considered obese. This is defined as an excess of normal levels of body fat. Alternative terms are adiposity or obeseness. Both expressions reflect that an unhealthy bodyweight to height ratio is present.

As soon as BMI is high enough to be classified as obese, women should take the necessary steps to counteract this. It is recommended to both change your diet and increase physical activity. A combination of a healthy diet and a lot of movement or exercise (as far as possible) is considered the optimal measure. If being overweight is due to an eating disorder, psychological support should be sought.

Calculate BMI for women

If you cannot or would prefer not to access the BMI calculator for women online, is it fairly simple to calculate your own BMI yourself. To calculate this, you only need your current bodyweight and height. Everything else can be calculated using the BMI formula.

BMI formula

If a woman would like to calculate her BMI, she should divide her bodyweight in kilograms (kg) by her height in metres squared (m). An example to explain: A woman weighs 75 kg and is 1.72 m tall. In this case, the calculation is: BMI = 75 kg / (1.72m * 1.72m). In this example, the woman’s BMI is 25.35 kg/m². The woman in, therefore, classed as “overweight” as her BMI is over 25 kg/m².

Criticism of BMI for women

Body Mass Index is often criticised. This applies to the BMI calculation for women as well as for men. Although the classification into BMI classes is specific for each gender, as women and men have different average proportions of body fat and muscle mass, very physically active or trained women may have a large amount of muscle mass which will have an effect on overall bodyweight. In these cases, women are sometimes classed as overweight although they are very fit and healthy. BMI should, therefore, only be used as a rough indicator of the ratio of weight to height. Finally, there are always other criteria to evaluate a healthy bodyweight as well as BMI.
