BMI for 145 cm and 80 kg
A person 145 cm (4'9") tall weighing 80 kg (176 lbs) has a BMI of 38.0 — classified as Obese. The healthy weight range for this height is 38.9–52.4 kg.
Your BMI score
Quick health screening — not a diagnosis
Your BMI falls within class II obesity, with high long-term health risk.
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?
Obesity class II · BMI 38.0 · Obese
A BMI of 38.0 falls in obesity class II (35–39.9). For 145 cm, body weight is about 27.6 kg above the upper healthy bound and roughly 53% above it.
This BMI band carries the strongest population-level health signal, but it's not deterministic. A clinician can interpret it alongside blood pressure, lipids, glucose, and body composition for a meaningful 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 145 cm tall, weights between 38.9 kg and 52.4 kg fall in the BMI 18.5–24.9 healthy range — roughly 86–115 lbs.

Target BMI milestones
Weights that would land at common BMI thresholds for 145 cm.
| Milestone | Target weight | vs current |
|---|---|---|
| BMI 40 (class III threshold) | 84.1 kg(185 lbs) | Gain ~4.1 kg |
| BMI 35 (class II threshold) | 73.6 kg(162 lbs) | Lose ~6.4 kg |
| BMI 30 (obesity threshold) | 63.1 kg(139 lbs) | Lose ~16.9 kg |
| BMI 25 (healthy range) | 52.6 kg(116 lbs) | Lose ~27.4 kg |
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.
