What BMI means
BMI stands for Body Mass Index and is a simple screening measurement based on height and weight.
It is commonly used to place results into broad categories such as underweight, normal weight, overweight, and obesity.
Although BMI is widely used, it is only a general screening tool and does not directly measure body fat or health status.
This calculator gives a quick estimate that can be helpful for general awareness and fitness planning.
For personalized health guidance, BMI should be considered together with other factors such as age, body composition, and medical advice.
