Our content is researched, written, and regularly updated by our editorial team using the A Bra That Fits (ABTF) methodology — the same approach validated by the 500,000+ member r/ABraThatFits community. We cite peer-reviewed research, lingerie industry standards, and community data. Our calculators process data locally in your browser; we do not collect body measurements.
We use the modern 6-measurement ABTF method rather than the outdated +4 inch rule. This approach has been independently validated by the r/ABraThatFits community to produce more accurate and comfortable bra sizes than traditional two-measurement methods.
