About SizeLoop
SizeLoop is a free utility site for one job: converting sizes between the measurement systems shoppers actually run into. US, UK, EU, JP, centimeters, inches. Pick a converter, get your size, buy with more confidence.
How the tables are built
Every conversion table on SizeLoop is compiled from official brand and retailer size charts, cross-checked across sources, and stamped with a last-reviewed date on the page. Tables are re-verified on a regular cycle, and any page whose tables change gets a new date stamp. If a number is on this site, it traces back to a chart a brand published, not to another blog.
The honesty limits
A conversion table maps foot or body measurements to size numbers. It cannot account for the last, the form each brand cuts its products around, or for vanity sizing. So treat every conversion as a starting point and confirm on the specific brand’s own size chart before ordering, especially between sizes. SizeLoop will never tell you a conversion is a guarantee. It is a verified starting point, and the brand’s chart has the last word.
Who runs SizeLoop
SizeLoop is run by an independent publisher. There is no editorial team to introduce and no office to visit. The site is supported by advertising, which keeps every tool free. If you spot an error in a table or a tool misbehaves, that is exactly the kind of message we want: contact SizeLoop.
What this site will not do
No reviews, no brand news, no fashion advice, no sponsored rankings. If it does not help you convert or measure fit, it does not belong here.
