Terms of Use
By using SizeLoop, you agree to these terms. If you do not agree, please do not use the site.
What SizeLoop provides
SizeLoop provides free size conversion tools and measuring guides for shoppers. The tools translate sizes between measurement systems such as US, UK, EU, and JP.
Conversions are estimates
Conversion tables are compiled from brand and retailer size charts and are re-verified on a regular cycle, but brands build on different lasts and adjust their sizing deliberately. Every conversion on this site is an estimate and a starting point, not a guarantee of fit. Always confirm against the specific brand’s own size chart before buying, especially between sizes.
No warranty
The tools and content are provided as-is, without warranties of any kind. We do not guarantee that a converted size will fit, that a purchase based on a conversion will work out, or that the site will be available without interruption.
Not professional advice
Sizing guidance on SizeLoop is a shopping aid. It is not medical, podiatric, tailoring, or any other form of professional advice.
Acceptable use
Do not misuse the site: no abusive automated scraping, no attempts to disrupt the tools, and no presenting SizeLoop’s content as your own work. You may link to our pages and share converted results freely.
Changes to these terms
These terms may be updated as the site grows. Continued use of the site after changes are posted means you accept the updated terms. Data handling is covered separately in our Privacy Policy.
