BMI (Body Mass Index) is a numerical value calculated from your height and weight that provides a quick assessment of your body fat and potential health risks. It is a widely used screening tool that helps indicate whether you are underweight, normal weight, overweight, or obese.
The BMI formula is:
BMI = Weight (kg) / Height² (m²)
In imperial units, the formula is:
BMI = [Weight (lbs) / Height² (inches²)] × 703
While BMI is a useful tool, it has some limitations:
Regular BMI tracking helps:
For general health monitoring, checking your BMI every 3-6 months is sufficient. If you're actively trying to lose or gain weight, monthly checks can help track progress.
BMI is less accurate for athletes, bodybuilders, pregnant women, and elderly individuals. It's best used as one of several health metrics.
Consult with a healthcare provider who can evaluate your overall health and provide personalized advice. BMI is just one screening tool.
The standard BMI calculation doesn't factor in age or gender, though these variables can impact healthy weight ranges. Our detailed analysis tool provides more personalized insights.
This calculator is designed for adults. For children and teens, specialized BMI-for-age charts should be used, as healthy ranges vary by age and gender during development.
