Bra Size Starting Estimate
Get a first-pass US band-and-cup estimate from two measurements.
Results are informational starting points. Clothing sizes vary by brand; tools do not replace a professional fitting or medical guidance.
Use the estimate as a fitting starting point
Band and cup labels vary with brand, construction and fitting method. The right fit should feel secure without digging, gaping or causing discomfort.
- Measure directly against the body without compressing the tape.
- Use the estimate as a first size to try, not as a promise of fit.
- Compare a sister size or seek a professional fitting if the band or cups feel uncomfortable.
This simple calculation is not an official fitting method and may differ from a brand’s chart.
