How to use this calculator:
Measure the same feature on both breasts using the same method and the same unit. Enter the larger-side and smaller-side measurements below.

Try to measure in a relaxed, consistent position and avoid pulling the measuring tape tightly.

Important: Natural breast asymmetry is common. This calculator is an educational comparison tool and does not diagnose a medical condition.

Choose what you are comparing on the two sides.

Measurement tip: Choose one method and use exactly the same method for both sides. The method helps interpret the comparison; the percentage calculation is based on the two values.

Enter the measurement of the larger side.

Enter the measurement of the smaller side.

What does this result mean?

The percentage is a simple comparison of the two measurements. It does not determine whether one breast is medically normal or abnormal.

Minimal: The measured difference is relatively small and may be difficult to notice.

Mild: There is a measurable difference that may be noticeable, especially in certain positions or clothing.

Moderate: The difference is more pronounced and may be easier to notice visually or through measurement.

Noticeable: The two measurements show a relatively larger difference. This still does not automatically mean that something is wrong or needs treatment.
