About Us
The story behind MyRingSizeCalculator.com, how our tools work, and who's behind them.
Our Story
At MyRingSizeCalculator.com, we believe the perfect ring should fit perfectly — no guesswork, no stress, and no last-minute resizing.
Founded in 2024, our mission is to make ring sizing simple, accurate, and accessible to everyone, whether you're planning a surprise proposal, buying jewelry online, or measuring for a custom-designed ring.
We've helped over 0.5 million people find their ideal ring size with our free tools and guides.
Our Vision & Mission
Our Mission
To make finding an accurate ring size simple, free, and accessible to everyone — replacing guesswork with a measurement you can actually trust, whether you're buying online, in person, or for someone else entirely.
Our Vision
A future where nobody buys a ring that doesn't fit. We want accurate, at-home sizing to be the default expectation for jewelry shoppers everywhere — not something you have to search for or guess at.
Why Trust Us
Accuracy You Can Check
Our calculator is built on the ISO 8653:2016 ring sizing standard, the same measurement basis used by jewelers internationally.
No Hidden Agenda
Every tool on this site is free to use, with no paid "premium" results. We're not affiliated with any jewelry brand.
Built for Real Use
Our guides cover the situations people actually run into — wide bands, knuckle adjustments, international sizing, and measuring for someone else.
Meet the Team
Erica Brain
"After buying the wrong-sized engagement ring twice, I built this tool so no one else would waste time or money."
Dr. Sarah Lee
"Most sizing mistakes happen at home. Our guides bridge the gap between DIY and professional fittings."
Alex Chen
"We refine our calculator continuously based on real user measurements."
Our Values
Transparency
We say plainly when a measurement method has limits, rather than overstating precision.
Inclusivity
Sizing guides for all genders, cultures, and ring styles — including wide bands, knuckle adjustments, and international standards.
Accuracy Over Hype
We'd rather tell you a printable sizer needs to be printed at true scale than promise perfect results with no caveats.
