The Smart BMI (SBMI) was created by biologist Christian Bachmann, in cooperation with David Fäh, M.D. And Heinrich von Grünningen, M.D. This site is not affiliated with Bachmann, Fäh, or von Grünningen and not the equivalent of their Smart BMI Calculator. BMI does not distinguish between muscle and fat, so athletes may have a higher BMI even if they are fit. Analyze pace across multiple checkpoints for advanced run tracking.
- Founded in 2023, our platform has helped over 500,000 users understand their weight health through accurate, research-backed tools.
- Body fat percentage requires special equipment or formulas to measure, while BMI only needs height and weight.
- Too frequent checking can be discouraging due to daily weight fluctuations.
- Enter your current weight in kilograms or pounds, depending on the selected unit.
- This would involve losing enough weight to reduce your BMI by 2.1 points.
- Please note that the dark and light-green ranges do not represent the same risk level.

If Your BMI is Healthy
The width of the green range has been set to fit the WHO definition of normal weight at the age of about twenty. The borders of the red ranges have been set to meet the WHO definitions of extreme obesity and underweight. In both cases, the risk curves for men and women differ because the study results show that women can tolerate more overweight and underweight than men. BMI works reasonably well for most heights. But extreme heights show less accurate results. People under 5 feet or over 6’4″ should rely more on body fat percentage and waist measurements.

The BMI Formula
Monitoring your Body Mass Index (BMI) is a quick and reliable way to understand your current weight status and overall health. Whether you’re setting fitness goals or managing your wellness journey, our online BMI calculator makes it easy, fast, and error-free. The calculator uses your Total Daily Energy Expenditure (TDEE), which is the total number of calories you burn in a day. It takes into account your basal metabolic rate (the calories you burn just by being alive), plus the calories burned through physical activity.
How BMI Works and What It Measures
Make gradual dietary improvements rather than dramatic changes. Join a support group or find an accountability partner. Start with small changes rather than drastic ones.
