BMI Calculator for Men
Estimate your Body Mass Index (BMI) and understand how your result relates to male-specific health risks.
Results
BMI
25.9
Interpretation
Overweight — review lifestyle and waist circumference.
Converted values: Height 178.0 cm • Weight 82.0 kg
How to Use This Calculator
Record accurate measurements
Remove shoes and stand tall against a wall for height. Use a calibrated scale for weight. Switch units if you prefer imperial measurements.
Review the BMI category
Men with higher muscle mass may have elevated BMI with low body fat. Consider additional tests (waist circumference, body fat percentage) for context.
Set lifestyle goals
Use your BMI to start a conversation about nutrition, strength training, and cardio. Small changes in BMI can reflect meaningful health improvements.
Formula
BMI = Weight ÷ Height²
- Metric: weight (kg) ÷ [height (m)]²
- Imperial: weight (lb) ÷ [height (in)]² × 703
- The same formula applies to men and women—interpretation differs when considering muscle mass and visceral fat.
Understanding BMI in Men
BMI correlates with clinical outcomes such as cardiovascular disease risk, but it cannot differentiate between lean mass and fat mass. Men who strength train may prefer additional markers such as waist circumference <94 cm and body fat 10–20%.
Underweight
BMI < 18.5 – consider reviewing caloric intake and training load.
Healthy weight
18.5 ≤ BMI < 25 – continue balancing nutrition, resistance, and aerobic exercise.
Overweight
25 ≤ BMI < 30 – focus on reducing visceral fat with diet and activity adjustments.
Obesity classes
BMI ≥ 30 – combine medical advice with structured lifestyle interventions.
Frequently Asked Questions
Does BMI account for muscle mass?
No. Muscular men may have BMI in the overweight range despite low body fat. Track waist circumference and body fat percentage for context.
What waist size should I target?
A waist circumference below 94 cm (37 in) is often recommended for men to minimize cardiometabolic risk.
How often should I monitor BMI?
Check every few months unless you are actively losing or gaining weight. Pair BMI readings with lab tests and blood pressure monitoring.
Can BMI predict health outcomes?
BMI is a screening tool. Elevated values prompt further evaluation of blood lipids, glucose, and lifestyle habits.
