Sizing is one of the biggest challenges for jewelry merchants: If customers don’t know their ring size or have to guesstimate it, they’re less likely to buy and more likely to return items.
Up until now, most shops have relied on clunky, printable sizing charts that require customers to print, use scissors, strings, or even measure with a ruler. A handful of shops have tried to digitize the process, but there's still no solution that sizes fingers (and not just rings).
Even in-store ring sizing can be unreliable – temperature changes and movement often cause finger swelling, leading to inaccurate measurements.

R11N and Large Office teamed up to tackle this challenge: building the best ring sizing app. We built a seamless, reliable, and digital way for merchants to offer highly accurate ring sizing to their customers.
So far, there are no other ring sizing apps designed specifically for merchants – meaning this is a true blue ocean market.
To make it even easier for shops to integrate, we built RingSizer as a Shopify that can be added in minutes. No developer needed.
