Reporting a sizing issue
If a calculator gave you a result that didn't match reality, please tell us the calculator name, the measurements you entered, and the brand you compared against (if any). Specific reports like this are the fastest way for us to improve accuracy for everyone.
Collaborations & Partnerships
We're open to hearing from other sites, publishers, and businesses in this space. If you're reaching out about any of the following, email us at hello@7tshirts.com with a short note on what you have in mind — a subject line like "Partnership: [what it's about]" helps us route it faster:
- Collaborations — joint content, co-created guides, or working together on a shared project
- Sponsorships — sponsoring a page, section, or one of our size calculators
- Guest posts — contributing an article to our blog, or having us contribute to yours
- Link exchanges & backlinks — relevant, genuinely useful link placements between our sites
- Product links & affiliate partnerships — featuring your product, or an affiliate arrangement, where it's genuinely relevant to what we cover
- Any other partnership — if it doesn't fit the categories above, tell us about it anyway; we're happy to consider most reasonable proposals
