BMI Calculator
Calculate your Body Mass Index (BMI) to determine if you are at a healthy weight for your height. Includes categories for adults.
BMI is a useful estimate, but doesn't take into account muscle mass or body composition.

Physiological Benchmarking
Body Mass Index (BMI) is a foundational metric for assessing the relationship between height and weight. Defined as a person's mass in kilograms divided by the square of their height in meters, it provides a rapid classification system for physiological categories.
Metric Classifications
For most adults, the ideal index is targeted within the 18.5 to 24.9 range.
- Underweight: Index below 18.5
- Healthy Weight: Index between 18.5 and 24.9
- Overweight: Index between 25 and 29.9
- Obese: Index exceeding 30
The Mathematical Model
Our tools utilize the standard World Health Organization (WHO) derivation:
BMI = weight (kg) / [height (m)]²
FAQ
While BMI is a vital screening instrument, it does not distinguish between adipose tissue and lean muscle mass. Athletes and elderly individuals may require additional body composition analysis for high-precision results.
The WHO identifies an index between 18.5 and 24.9 as the optimal 'Healthy' range for adults to minimize metabolic risk factors.
