01 Overview

No equipment, no cost, no appointment

Although BMI does not directly measure body fat and other factors in women, it is still a reliable option to determine whether a person is underweight, overweight, or obese. Also, measuring body fat is a costly method and requires expert evaluation. With our BMI calculator for women, you just need to enter your height and weight to get an estimate without any specialised equipment.

Our BMI tool also supports both units, i.e., imperial units (feet, inches, stone and pounds) and metric units. This simple feature allows you to enter data in your most familiar units of height and weight to ensure better understanding of results. Whether you know your weight in stone and pounds or kilograms and height in feet or centimetres, just enter the correct information in the given box and quickly assess your health.

Understanding your BMI category helps you determine whether you are underweight, normal, overweight, or obese. This simple test helps you maintain a healthy lifestyle and saves you from future health issues. Doctors also use a BMI calculator as part of a health evaluation to customise a health plan with all required changes according to the BMI value to achieve a healthy weight goal within an appropriate period.

05 Body composition

Does BMI Differ for Women and Men?

The formula for standard BMI calculation is weight divided by height squared (weight / height²), which is the same for both men and women. The body weight chart for adults describes a normal BMI range from 18.5 to 24.9 and an overweight range from 25 to 29.9 for everyone aged 20 or above.

Female body

  • Generally possesses a higher percentage of body fat
  • Generally has less muscle mass
  • Experiences hormonal changes throughout the lifespan, like during pregnancy, menopause, or conditions like PCOS

Shared BMI ranges

  • Normal BMI range: 18.5 to 24.9
  • Overweight range: 25 to 29.9
  • Applies to everyone aged 20 or above, male or female

However, there is a huge difference between the body composition of males and females. Therefore, it is important to understand that even with the same BMI formula, the BMI interpretation for a woman's body is completely different. BMI calculators are not interpreted as a complete measure of health. Therefore, for better health evaluation, doctors often add more tests to measure body composition, like measuring waist-to-height ratio.

07 Health risks

Health Risks Associated With a High BMI and Low BMI

Whether you are overweight or underweight, both situations come with serious diseases and health conditions. With a higher BMI, a person is more prone to heart-related issues, while a low BMI can be a sign of some underlying condition.

High BMI

Source: CDC

If your BMI value is in the high BMI category, the outcome can be a serious disease, even fatal in some cases. According to the Centers for Disease Control and Prevention (CDC), with high BMI, a person has a major risk of the following health conditions:

  • Heart disease
  • Stroke
  • Gallbladder disease
  • High blood pressure
  • Osteoarthritis
  • Mental illnesses such as clinical depression and anxiety
  • Type 2 diabetes
  • Frequent body pains
  • Higher levels of LDL cholesterol
  • Certain cancers, including colon, breast and uterine

A BMI value above 25 kg/m² falls under the category of overweight. However, if you are on the higher side, consult your doctor to make healthy lifestyle changes for a positive outcome.

Low BMI

Also linked to serious conditions

Although high BMI sounds more dangerous, there are still many serious health risks associated with low BMI. Here are the possible health issues one can face with a low BMI:

  • Malnutrition
  • Serious reproductive issues for women, such as infertility
  • Growth and development issues
  • Anaemia
  • Weak immune system
  • Potential complications after surgery
  • Osteoporosis

If there is no visible cause of low BMI, it is advised to consult a healthcare professional to find the underlying condition, like anorexia nervosa. Proper medication and healthy lifestyle changes are needed in order to be healthier.

08 Habits

How to Support a Healthy Weight

To maintain your body weight within a healthy BMI range, focus on a nutritious diet, regular physical activity, adequate sleep, and adopting healthy habits, like skipping junk foods, sleeping early, etc. Whether you want to gain or lose weight, the best option is to set realistic goals and seek professional assistance from a registered dietitian, healthcare provider, or health coach.

  • Nutritious diet

    Focus on nutritious food and skip junk foods.

  • Regular activity

    Keep up regular physical activity in your routine.

  • Adequate sleep

    Get adequate sleep and adopt habits like sleeping early.

  • Realistic goals

    Set realistic goals and seek professional assistance.

09 Limitations

What Are the Limitations of BMI?

Although BMI is a useful indicator of body weight, it is still just a screening measure, not a diagnosis. The BMI formula only indicates the excess body weight of a person, without taking body composition into account, such as the distribution of muscle, bone mass, and fat. Also, there are multiple other factors that influence the healthy body weight of a person, such as age, sex, ethnicity, muscle mass, body fat, and activity level.

For instance, an older person with no physical activity has the same healthy BMI value as a younger person with regular physical activity. In such a case, the older person must have excess body fat within the healthy BMI range, while the younger person has higher muscle composition with a very low body fat percentage.

However, with all these limitations, the BMI value is still a trusted option along with other measures to identify the healthy weight of a person. Also, a person who has no serious health issues can use our BMI calculator for a quick assessment of their body weight without spending any real money.

12 FAQs
