XXL Sizes is an independent website that explains sizes in plain language. We started it because size labels are confusing. An XL from one brand fits like an L from another, a “42” can mean a chest or a collar, and even dog crates and mouse pads use XXL without agreeing on what it means.

What We Do

We publish practical size guides, conversion charts and buying tips for shoppers in the US, the UK and Europe. Our main topics are:

How We Write Our Guides

Every chart on this site is built from published brand size charts, manufacturer specifications and well-known standards. When a number varies between brands, we say so and give a range rather than pretending there is one right answer. We also link to our sources so you can check them yourself.

We update guides when brands change their charts or prices move. Each article shows the date it was last updated.

Our Promise to Readers

  • We don’t accept payment to rank or recommend a product.
  • We clearly label any advertising on the site.
  • We correct mistakes quickly when readers point them out.
