About SizeTranslate
Shopping internationally should be exciting, not confusing. Yet one of the biggest frustrations for global shoppers is figuring out how sizes translate between countries. A US 9 shoe is not the same number as a European 42, and a UK dress size 12 means something completely different in the US system.
SizeTranslate was built to solve this problem. We provide instant, accurate size conversions across 13+ international sizing systems, covering shoes, clothing, rings, and bras. No ads blocking the answer, no slow loading, no confusing interfaces — just the size you need, instantly.
How Our Data Works
Our size conversion data is compiled from international standards and verified against multiple authoritative sources including ISO standards, major brand size guides, and industry references. We cover sizing systems from the United States, United Kingdom, Europe, Japan, China, South Korea, Australia, Brazil, Mexico, Italy, France, Germany, and international (S/M/L) standards.
Important Disclaimer
While we strive for accuracy, please keep in mind that sizes can vary between brands and manufacturers. Our conversions are based on standard international charts and should be used as a general guide. We always recommend:
- Checking the specific brand's size guide when available
- Measuring yourself using our measurement guides
- Reading customer reviews for fit advice on specific products
- Ordering from retailers with easy return policies when trying new brands
Our Technology
SizeTranslate is built for speed. Every page is pre-rendered as static HTML, served from a global CDN, and loads in under a second. The site works fully without JavaScript — the conversion data is baked into the HTML. Interactive features like the real-time converter enhance the experience but are not required.
