BMI for 177 cm and 105 kg
A person 177 cm (5'10") tall weighing 105 kg (231 lbs) has a BMI of 33.5 — classified as Obese. The healthy weight range for this height is 58.0–78.0 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 33.5 · Obese
33.5 is in the class-I obesity band. For 177 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.
BMI is a screening tool, not a diagnosis. It doesn't know the difference between fat and muscle, doesn't measure where weight sits on the body, and doesn't account for age, sex, or ethnicity-specific cutoffs.
For someone 177 cm tall, weights between 58.0 kg and 78.0 kg fall in the BMI 18.5–24.9 healthy range — roughly 128–172 lbs.

Target BMI milestones
Weights that would land at common BMI thresholds for 177 cm.
| Milestone | Target weight | vs current |
|---|---|---|
| BMI 40 (class III threshold) | 125.3 kg(276 lbs) | Gain ~20.3 kg |
| BMI 35 (class II threshold) | 109.7 kg(242 lbs) | Gain ~4.7 kg |
| BMI 30 (obesity threshold) | 94.0 kg(207 lbs) | Lose ~11.0 kg |
| BMI 25 (healthy range) | 78.3 kg(173 lbs) | Lose ~26.7 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.
