BMI for 165 cm and 100 kg
A person 165 cm (5'5") tall weighing 100 kg (220 lbs) has a BMI of 36.7 — classified as Obese. The healthy weight range for this height is 50.4–67.8 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 36.7 · Obese
36.7 sits in the class-II obesity range. At 165 cm, this is well past the overweight band and meaningfully above the healthy ceiling.
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 165 cm tall, weights between 50.4 kg and 67.8 kg fall in the BMI 18.5–24.9 healthy range — roughly 111–149 lbs.

Target BMI milestones
Weights that would land at common BMI thresholds for 165 cm.
| Milestone | Target weight | vs current |
|---|---|---|
| BMI 40 (class III threshold) | 108.9 kg(240 lbs) | Gain ~8.9 kg |
| BMI 35 (class II threshold) | 95.3 kg(210 lbs) | Lose ~4.7 kg |
| BMI 30 (obesity threshold) | 81.7 kg(180 lbs) | Lose ~18.3 kg |
| BMI 25 (healthy range) | 68.1 kg(150 lbs) | Lose ~31.9 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.
