BMI is a general screening measurement for adults and is not a medical diagnosis. It may not accurately represent health for athletes, pregnant individuals, older adults or people with higher muscle mass. Consult a qualified healthcare professional for personalized medical advice.
A BMI Calculator checks whether your weight is suitable for your height. It calculates your Body Mass Index and places the result in a general weight category.
BMI stands for Body Mass Index. It is a simple measurement that compares your body weight with your height and helps screen your general weight status.
A BMI Calculator divides your weight in kilograms by your height in metres squared. It then compares the result with standard adult BMI categories.
You normally need to enter your height and weight. A calculator for children and teenagers may also ask for age and sex to calculate BMI percentile.
Use this formula: BMI equals weight in kilograms divided by height in metres squared. For example, divide 70 kilograms by 1.75 metres multiplied by 1.75.
Divide your weight in pounds by your height in inches squared. Multiply the result by 703. An online BMI Calculator performs this calculation automatically.
For most adults, a BMI between 18.5 and 24.9 is considered a healthy weight range. However, BMI should be considered with other health information.
A BMI below 18.5 is classified as underweight for adults. Low weight can sometimes be connected with nutritional deficiencies or health problems requiring professional advice.
An adult BMI from 25 to 29.9 is classified as overweight. This is a screening result and does not automatically mean that you have a health condition.
For adults, a BMI of 30 or higher is classified as obesity. It is divided into Class 1, Class 2 and Class 3 obesity.
A BMI Calculator accurately compares weight with height, but it cannot fully measure personal health. Medical history, body composition, lifestyle and laboratory results may also matter.
No. Children and teenagers should use a child BMI Calculator. Their results are interpreted using BMI-for-age percentiles based on their age and sex.
A BMI percentile compares a child’s BMI with children of the same age and sex. It helps healthcare professionals understand the child’s weight and growth pattern.
Standard adult BMI categories are generally the same for men and women. However, BMI does not show differences in muscle mass, body fat percentage or fat distribution.
A standard BMI Calculator is not suitable for measuring weight changes during pregnancy. Pregnant women should follow personalised weight and health advice from their doctor or midwife.
Use your BMI as a general screening result, not a diagnosis. Consider your waist size, lifestyle and medical history, and speak with a healthcare professional about concerns.
