How to Measure Your Ring Size

Jewelers all across North America use standard U.S. ring sizes. If you want to know your U.S. ring size, first take a string and measure the circumference of a ring you currently wear, or by measuring your finger. 

Jewelers all use the same chart, with only minor differences when they round the result. Because of this, your finger might measure one size at a jeweler and another slightly different size at another jeweler

No Roses Artisan Jewelry's ring size conversion chart will help you convert your string to an actual ring size! We also offer a free ring sizer - just send your name and postal mailing address to info@norosesjewelry.com. Depending on your location, it will take 2 - 5 days for the sizer to arrive.
