      Contact SizeSwapper

      Have a question, found an issue, or want to request a brand or comparison? Here's the best way to reach us for each.

      Report outdated or incorrect sizing

      Use the “report an issue” link shown alongside any conversion result — it tells us exactly which brand and page you were looking at, which makes it much faster for us to check and fix.

      Request a brand or comparison

      Use the “request a brand or comparison” option directly inside the size converter. Requests with clear demand get prioritised for the next data update.

      Everything else

      For general questions, partnership enquiries, or anything not covered above, reach out via the converter's request form and mark it as a general enquiry — we read every submission.

      Response times

      SizeSwapper is independently run, so responses aren't instant, but every report and request is reviewed.
