Your BMI score
Quick health screening — not a diagnosis
Your BMI is above the recommended range and may increase health risks.
What this means
BMI is a quick screening number based only on height and weight. It doesn't distinguish muscle from fat, and shouldn't replace a clinical assessment.
- 18.5–24.9 generally lowest health risk
- 25–29.9 elevated metabolic risk
- 30+ higher long-term risk

What does this BMI mean?
Overweight · BMI 29.1 · Overweight
A BMI of 29.1 falls in the overweight band (25–29.9). At 171 cm, 85 kg is about 12.2 kg above the upper healthy bound of 72.8 kg.
BMIs in the 25–29.9 range are common and not automatically alarming, but they're worth pairing with waist circumference and basic bloodwork to see the fuller picture.
One number can't capture body composition. BMI is useful for population comparison and as a rough self-check, but pairing it with waist circumference or body-fat measurement gives a much more honest read.
For someone 171 cm tall, weights between 54.1 kg and 72.8 kg fall in the BMI 18.5–24.9 healthy range — roughly 119–161 lbs.

Why BMI isn't the whole story
- Muscle vs fat: BMI treats a kilogram of muscle the same as a kilogram of fat. Strength athletes and very muscular builds can land in the overweight band while having low body fat.
- Body shape matters: Two people at the same BMI can carry weight very differently. Waist circumference and waist-to-height ratio capture risk that BMI misses.
- Age, sex, ethnicity: The 18.5–24.9 window is a single global average. Cutoffs adjusted for ethnicity and age can shift the interpretation, especially at the edges of the band.
- Still useful: BMI remains widely used because it's cheap, fast, and roughly predictive at population scale. Treat it as a self-check signal, not a diagnosis.
