BMI for 158 cm and 85 kg
A person 158 cm (5'2") tall weighing 85 kg (187 lbs) has a BMI of 34.0 — classified as Obese. The healthy weight range for this height is 46.2–62.2 kg.
Your BMI score
Quick health screening — not a diagnosis
Your BMI falls within class I obesity, with elevated 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 I · BMI 34.0 · Obese
34.0 is in the class-I obesity band. For 158 cm, this is the first obesity tier — typically the easiest to move out of with sustained changes.
Sustained BMI in the obese range is linked with higher risk for several chronic conditions — type-2 diabetes, sleep apnea, cardiovascular disease, joint stress. The good news is that even modest, sustained weight loss (5–10%) tends to produce outsized health benefits.
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 158 cm tall, weights between 46.2 kg and 62.2 kg fall in the BMI 18.5–24.9 healthy range — roughly 102–137 lbs.

Target BMI milestones
Weights that would land at common BMI thresholds for 158 cm.
| Milestone | Target weight | vs current |
|---|---|---|
| BMI 40 (class III threshold) | 99.9 kg(220 lbs) | Gain ~14.9 kg |
| BMI 35 (class II threshold) | 87.4 kg(193 lbs) | Gain ~2.4 kg |
| BMI 30 (obesity threshold) | 74.9 kg(165 lbs) | Lose ~10.1 kg |
| BMI 25 (healthy range) | 62.4 kg(138 lbs) | Lose ~22.6 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.
