Calculate your Body Mass Index with instant health category interpretation
Enter your measurements to see results
Input your height in either centimeters or feet and inches. Make sure to use accurate measurements for best results.
Input your weight in either kilograms or pounds. Weigh yourself at the same time of day for consistency.
Click the calculate button. The tool will instantly compute your BMI and display the result.
See which BMI category you fall into: Underweight (below 18.5), Normal (18.5-24.9), Overweight (25-29.9), or Obese (30 and above).
Remember that BMI is a screening tool, not a diagnostic. It doesn't account for muscle mass, bone density, or body composition.
If your BMI is outside the normal range, consult with a healthcare provider for personalized advice and assessment.
Use the calculator regularly to track changes in your BMI over time as you work toward your health goals.
Remember that BMI is just one indicator. Consider other factors like waist circumference, body composition, and overall health.
A healthy BMI typically falls between 18.5 and 24.9. Below 18.5 is considered underweight, 25-29.9 is overweight, and 30 or above is considered obese.
BMI is a useful screening tool but has limitations. It may overestimate body fat in muscular individuals and underestimate it in older adults who have lost muscle mass.
Yes, BMI interpretation differs for children and teens. It's compared to growth charts based on age and sex, not fixed thresholds like adults.
No, BMI doesn't distinguish between muscle and fat. A very muscular person may have a high BMI but low body fat percentage.
There's no set frequency, but checking monthly can help track progress. Remember that daily fluctuations are normal due to water weight and other factors.
If your BMI is in the overweight or obese range, consult with a healthcare provider. They can help create a personalized plan for healthy weight management.
BMI correlates with certain health risks, but it's not a direct predictor. Other factors like genetics, lifestyle, and body composition also play important roles.
The BMI formula is the same, but body composition differs between sexes. Women typically have more body fat than men at the same BMI.
BMI estimates body fat based on height and weight, while body fat percentage directly measures fat mass. Body fat percentage is more accurate but requires special equipment.
BMI may not be accurate for athletes with high muscle mass. Consider using body fat percentage or consulting with a sports nutritionist for better assessment.
