Affiliate Disclosure
Last updated: 17 October 2026
In short: Bra Size is free to use. Some links on the site may earn us a small commission or be part of a sponsorship. That never changes the price you pay, and it never changes what our calculators tell you.
How the site is funded
Every calculator, chart and guide on Bra Size is free, with no sign-up and no paywall. To keep it that way, we may earn money in a few ways:
- Affiliate links. If you follow a link to a retailer or brand and buy something, that business may pay us a commission.
- Sponsorships. A brand or business may sponsor a page, a section or a guide.
- Partner placements. Featured products, services or links agreed with a partner. See collaborations & partnerships.
What never changes
Calculators stay neutral
Our sizing formulas are the same for everyone. No partner can change a calculation, a conversion or a size result.
You pay the same
Any commission comes from the retailer, not from you. Using our link doesn't add to your price.
Paid means labelled
Sponsored sections and paid placements are marked as such, close to the content they relate to.
Editorial choices are ours
We only include products or links we think are genuinely useful for the topic, and we can turn down any proposal.
How to spot a paid link
Where a page contains affiliate or sponsored links, we say so on that page with a short note such as "This page contains affiliate links" or a "Sponsored" label. If you're ever unsure whether a link is paid, email us and we'll tell you.
Health and medical topics
We don't accept payment to publish health, medical or body-change claims, and we don't promote products that promise to change breast size or shape. Our content is about clothing fit only. Read our Disclaimer for more.
Following disclosure rules
We aim to follow the spirit of advertising-disclosure guidance in the places our readers live, which generally asks that paid relationships be clear and easy to notice.
