Calculate your BMI with Moshy
Checking your BMI is quick and easy with Moshy’s online body mass index calculator. Simply enter your height and weight to see your result instantly.
Body mass index, or BMI, is used to determine whether you are in a healthy weight range for your height. It is useful to consider your waist circumference as well as your BMI.
Understanding Your BMI Result
For Australian adults, BMI results are grouped into the following categories[1]:
Underweight: BMI less than 18.5
Healthy weight: BMI 18.5–24.9
Overweight: BMI 25–29.9
Obese: BMI 30 or higher
A healthy BMI range for most adults is between 18.5 and 24.9. Your BMI result can help you understand whether you may benefit from making changes to your lifestyle or seeking professional support. Keep in mind that age, gender, and body composition (such as muscle mass) can influence your BMI result.
While BMI is a useful screening tool, it does have limitations:
Athletes: High muscle mass can result in a higher BMI, even if body fat is low.
Pregnancy: BMI does not account for pregnancy-related weight changes.
Certain ethnicities: Some groups may have different health risks at the same BMI.
Children and older adults: BMI categories differ for children and may not reflect health risks in older adults[3].
Waist measurement is another important indicator of health, as carrying excess weight around your middle can increase your risk of chronic diseases, even if your BMI is in the healthy range[4].

Why Does BMI Matter?
Body Mass Index (BMI) is a simple tool used to estimate whether you are in a healthy weight range for your height. It is calculated by dividing your weight in kilograms by your height in metres squared (kg/m²). BMI is widely used by health professionals to screen for weight categories that may lead to health problems, such as being underweight, overweight, or obese[1]. Knowing your BMI can help you understand your risk for certain health conditions, including heart disease, type 2 diabetes, and high blood pressure[2].

Frequently asked questions
BMI is a reliable screening tool for most adults, but it does not directly measure body fat or account for muscle mass, bone density, or distribution of fat[1].
Other factors like waist measurement, family history, physical activity, and overall health are important. A healthcare professional can help you assess your health risks more accurately[4].
Yep. In most cases, weight management solutions can be organised by one of our health practitioners based on an online visit which may include a video, phone call, or consultation with a health practitioner by text, and self-reporting your symptoms and your medical history.
Healthy eating, regular physical activity, and support from a qualified practitioner can help you reach and maintain a healthy weight[2]. Moshy’s programs are designed to provide expert guidance and ongoing support
