Terms & Sizing Disclaimer

What a calculated size does and does not mean, plus the usual terms.

A calculated size is an estimate, not a guarantee of fit. Bra sizing is not standardised. The same nominal size differs between brands, between ranges within a brand, and between styles within a range. Treat every result here as the first size to try on.

Sizing disclaimer

  • The calculator produces an estimated starting size from two measurements using a published, versioned method. It cannot account for breast shape, tissue density, root width, asymmetry or a specific brand’s grading.
  • We do not warrant that any size will fit, be comfortable, or be available.
  • Charts and conversions on this site describe widely used conventions. They do not override the chart published by the brand you are buying from.
  • Measurement error at home is normal. A result near a size boundary is flagged as such precisely because it could reasonably go either way.

Not medical advice

Nothing on this site is medical advice, diagnosis or treatment, and nothing here should be read as a claim about breast health. If you have pain, a lump, skin changes, or any physical concern, speak to a doctor. Do not delay seeking medical advice because of anything you read here.

Use of this site

  • You may use the calculator and read the guides for your own personal, non-commercial purposes.
  • You may not scrape, bulk-download, republish or resell our charts, guides or calculator, or present its output as your own tool.
  • You may quote short extracts with attribution and a link.
  • You may not attempt to interfere with the site, its security, or its availability.
