BMI for 55 kg and 152 cm
Instant answer: A person who weighs 55 kg (121 lbs) and is 152 cm (4'12") tall has a BMI of 23.8, classified as normal weight.
For an adult who is 152 cm tall, the World Health Organization considers a weight between 42.7 and 57.5 kg to be healthy.
What the numbers mean for you
You have 2.8 kg (6 lbs) of headroom before crossing into overweight (BMI 25 = 57.8 kg (127 lbs)).
Your BMI band midpoint is BMI 21.7 (50.1 kg (110 lbs)), often used as the "most protective" reference in cohort studies.
Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.
What does a BMI of 23.8 mean?
Multi-decade studies (notably the NIH-AARP cohort of more than 500,000 adults) link this BMI band to the lowest all-cause mortality.
BMI is a screening tool, not a diagnosis. Two people at 55 kg and 152 cm can have very different body compositions and very different health profiles. Use BMI alongside waist circumference, fitness level, and routine bloodwork.
Waist matters more than the scale
Two people can share the same BMI and have very different metabolic risk. For that reason, waist circumference is now considered a stronger predictor of cardiometabolic disease than BMI alone.
- Waist-to-height rule: keep your waist under half your height — that means below 76 cm (30") at 152 cm.
- Absolute cutoff for most adults: waist under 94 cm (37") is associated with meaningfully lower risk of type 2 diabetes and cardiovascular disease.
- Higher-risk zone: waist above 102 cm (40") — this is where risk climbs sharply regardless of BMI.
