BMI Calculator for Men
Understanding how BMI applies to men, including considerations for muscle mass and male-specific body composition. Use our BMI calculator to find your BMI, or learn more about what constitutes a healthy BMI.
BMI Ranges for Men
The same BMI ranges apply to both men and women. However, men tend to have higher muscle mass and lower body fat percentages compared to women.
| BMI Range | Category | Health Risk |
|---|---|---|
| < 18.5 | Underweight | Increased risk of nutritional deficiencies |
| 18.5 - 24.9 | Normal weight | Lowest health risk |
| 25.0 - 29.9 | Overweight | Moderate health risk |
| 30.0 - 34.9 | Obese Class I | High health risk |
| ≥ 35.0 | Severely obese | Very high health risk |
Muscle Mass & BMI
Men typically have higher muscle mass than women. Athletes, bodybuilders, and men who engage in regular strength training may have BMI readings that classify them as "overweight" despite having healthy body fat percentages.
For example, a muscular man who weighs 200 lbs (90.7 kg) at 6 feet (183 cm) tall would have a BMI of: For athletes, see our BMI guide for athletes.
BMI = 90.7 ÷ (1.83 × 1.83) = 27.1
This would classify as "overweight" despite potentially healthy body composition
Common BMI Mistakes for Men
Ignoring Muscle Mass
Many men focus on BMI without considering that muscle is denser than fat. Regular weight training can increase BMI while improving health.
Not Considering Age
As men age, metabolism slows and muscle mass naturally decreases. Older men may need to maintain slightly higher BMI for optimal health.
Focusing Only on Numbers
BMI should be one of many health indicators. Body fat percentage, waist circumference, and overall fitness are also important.
Health-Focused Approach
Rather than obsessing over BMI numbers, focus on:
- Regular physical activity
- Balanced nutrition
- Adequate sleep
- Stress management
- Regular health check-ups
Medical Disclaimer
Important: BMI is a screening tool, not a diagnostic tool. It provides an estimate of body fat based on height and weight but does not directly measure body fat percentage, muscle mass, bone density, or overall health.
BMI should not be used as the sole indicator of health. Many factors influence health beyond BMI, including:
- Body composition (muscle vs. fat)
- Waist circumference and body fat distribution
- Physical fitness and activity levels
- Medical history and family history
- Blood pressure, cholesterol, and blood sugar levels
- Lifestyle factors (diet, exercise, sleep, stress)
