Useful guidance.
Honest boundaries.

What we publish

We explain size labels, calculation methods and practical garment fit. Our tools are educational starting points. We do not assign body value to a cup size, estimate breast weight from a letter or promise a perfect fit.

Our source hierarchy

Manufacturer charts support label conversions. Established fitting resources inform practical checks. Community discussions help identify questions and points of confusion, but anecdotes do not establish a universal sizing rule. Source names sit beside the tools and guides they inform. Our methodology describes which chart and calculation rules are used.

Authorship and evidence

G Cup Bra Guide is the publishing name for this site. Content and software are developed with AI assistance. We do not claim certified fitter review, clinical validation, personal wear testing or a named expert endorsement. A functioning calculator is evidence of its stated arithmetic, not proof that every garment will fit.

Read our calculation rules and supported chart ranges before relying on a result. Report a problem through our sizing correction contact form.

Commercial content

Our current shopping guides compare construction features. We do not claim to have worn or tested products, checked live stock or verified prices when we have not. A future product ranking requires dated product evidence and a clear explanation of the selection process.

Corrections and review

Send a page URL, the sizing system and the source of a suspected error through the contact page. We prioritise calculation and chart errors and review related examples when a shared rule changes. A review date records a content check, not a promise of continuously monitored stock.

Language and accessibility

Supporting guides are written in English. Locale routes provide a language entry point; untranslated material must be identified rather than presented as professionally localised. We use text labels, keyboard controls and alternatives to visual explanations.
