How to use this calculator
- Enter weight, height.

Use consistent units and check the assumptions below before applying the result.
How overweight is calculated
BMI=weight(kg)/height(m)². The BMI-25 comparison weight is 25×height(m)²; the difference is shown only when current weight is above that reference. This is a screening threshold for adults, not a health boundary; muscularity, body composition, age, and clinical context all affect interpretation. At 1.70 m, BMI 25 corresponds to 72.25 kg.
BMI=weight(kg)/height(m)²; adult comparison threshold 25.At 1.70 m, BMI 25 corresponds to 72.25 kg.
Assumptions & useful context
Adult BMI is a screening measure, not a diagnosis.
Health calculations are estimates for education. They cannot diagnose a condition or replace a clinician’s assessment. Individual needs vary, especially during pregnancy, illness and growth.
Frequently asked questions
Does BMI above 25 mean I am unhealthy?
No. BMI is one screening measure and should be interpreted with other information.
Is the same cutoff used for children?
No. Children and teens use age- and sex-specific BMI percentiles.
