BMI Tracker
Body mass index, category, and a healthy weight range.
BMI is a screening tool, not a diagnosis — it doesn't account for muscle mass, bone density, or body composition. Talk to a healthcare provider for personalized guidance.

Where you fall on the scale
A healthy weight range for your height is approximately 57–76 kg.

What BMI does and doesn't measure
Body Mass Index divides your weight by the square of your height, giving a quick, population-level estimate of whether your weight falls in a typical range. It's widely used because it's simple and free to compute, but it can't distinguish muscle from fat — athletes with high muscle mass often score "overweight" despite low body fat. Use BMI as one data point alongside waist circumference, body fat percentage, and how you actually feel, not as a standalone verdict.
Frequently asked questions
Why does BMI ignore muscle mass?
BMI is just weight divided by height squared — it can't distinguish muscle from fat, so muscular people (athletes, bodybuilders) are often classified as "overweight" or "obese" despite low body fat. Body Fat % or Waist-to-Height Ratio are better markers when that applies to you.
Where do the BMI categories come from?
The standard WHO thresholds: under 18.5 is underweight, 18.5–24.9 is normal, 25–29.9 is overweight, and 30+ is obese. These bands are population-level screening tools, not individual diagnoses.
Is BMI equally accurate for everyone?
No — it's known to be less reliable for very muscular people, older adults (who naturally lose muscle), and it doesn't adjust for sex-based differences in body composition. It's a quick screening number, not a complete health assessment.
