Male-specific context
Calculate your BMI (Body Mass Index) as a man using metric or imperial measurements. Get your score and weight category with context specific to men, including muscle mass considerations that standard charts often miss.
Disclaimer: BMI is a screening tool, not a medical diagnosis. Consult a doctor for health advice.
Your Details
Your BMI is 26.2, which falls in the Overweight category. Remember: BMI cannot distinguish muscle from fat -- a muscular man may read overweight despite having low body fat.

The calculation
Step-by-step: how your BMI was calculated
Here is exactly how the calculation works.
1
Convert height to metres
Height (m) = height (cm) / 100
= 180 / 100
= 1.800 m
2
Square the height in metres
Height² = height (m) x height (m)
= 1.800 x 1.800
= 3.2400 m²
3
Divide weight by height squared
BMI = weight (kg) / height² (m)
= 85 / 3.2400
= 26.2 BMI
Context
BMI for Men: What the Numbers Mean
Key context for men: BMI cannot distinguish muscle from fat. A heavily muscular man with very low body fat can have the same BMI as an overweight sedentary man. Always combine BMI with waist circumference for a complete picture.
The muscle mass problemMen naturally carry more skeletal muscle than women. Men who strength-train regularly can have significantly more. A competitive powerlifter at 6 ft and 220 lbs (100 kg) would have a BMI of about 30.3 -- technically obese -- despite potentially having 12% body fat. For most men who are not elite athletes, however, a BMI above 25 does reflect genuine excess fat.
Waist circumference: the essential companion measureA healthy waist circumference target for men is under 94 cm (37 inches). Central fat accumulation above this threshold elevates cardiovascular risk independently of BMI. A man with BMI 26 and waist 90 cm has a very different risk profile than a man with BMI 26 and waist 100 cm.
Strategy
Quick Tips for Men Tracking BMI
Combine metrics
If you strength-train regularly, combine BMI with waist circumference and body fat percentage.
Waist targets
Waist target for men: under 94 cm (37 in) -- risk rises at 94 -- 102 cm and is high above 102 cm (40 in).
Preserve muscle
Resistance training while losing weight preserves muscle, keeping BMI meaningful during a weight-loss phase.

FAQ
Frequently asked questions
Q
What is a healthy BMI for men?The standard healthy BMI range for adult men is 18.5 to 24.9. Below 18.5 is considered underweight, 25 to 29.9 is overweight, and 30 or above is classified as obese. These are the same WHO ranges that apply to women, but context matters more for men because of differences in muscle mass.
Q
Does BMI account for muscle mass in men?No - BMI cannot distinguish between muscle and fat. Two men with identical heights and weights will have the same BMI even if one is lean and muscular while the other carries excess body fat. This is why muscular men such as athletes and bodybuilders often register as overweight or obese by BMI despite having very low body fat. Use BMI alongside other measures like waist circumference for a fuller picture.
Q
What BMI is considered obese for a man?A BMI of 30.0 or above is classified as obese for adult men. This threshold is the same for women. Within the obese range, Class I is 30 -- 34.9, Class II is 35 -- 39.9, and Class III (severe obesity) is 40 and above.
Q
How is BMI calculated for men?The formula is identical for men and women. Metric: BMI = weight (kg) / height^2 (m). Imperial: BMI = (703 x weight in lbs) / height^2 (inches). For example, a man weighing 85 kg at 1.80 m has a BMI of 85 / (1.80 x 1.80) = 26.2, placing him in the overweight category.
Q
What is the average BMI for men?In many Western countries, the average BMI for adult men sits between 26 and 28 -- technically in the overweight range. However, average does not mean healthy. The ideal target remains 18.5 -- 24.9 regardless of population averages.
Q
Is BMI the best way for men to track body composition?BMI is a useful starting point but not the most accurate measure of body composition for men. Better alternatives include waist-to-height ratio, waist circumference, DEXA scan body fat percentage, and the waist-hip ratio. That said, BMI is free, fast, and well-validated for screening at the population level.
Q
Can men have a healthy BMI but still be unhealthy?Yes -- this is known as 'normal weight obesity' or 'skinny fat'. A man can have a BMI in the 18.5 -- 24.9 range while carrying excess visceral (abdominal) fat and low muscle mass. Waist circumference above 94 cm (37 inches) is an independent risk factor for metabolic disease even in men with normal BMI.
Q
How accurate is this BMI calculator for men?This calculator uses the standard WHO BMI formula, which is medically accurate for adult men aged 18 and over. It is not designed for boys under 18, pregnant individuals, or professional athletes who may have atypically high muscle mass. Always pair the result with clinical judgement or a healthcare professional's advice.
