Ring Size Guide

Welcome to our Ring Size Guide!

Finding the perfect ring size can be a challenge, especially if you're shopping for someone else's ring. But don't worry, we've got you covered! Our comprehensive guide will help you find the best fit, no matter where you are.

First, let's start with the basics. Rings are usually measured in millimetres (mm), but sizes can also be expressed in US, UK, EU or other standard sizes. The size of a ring is determined by the inside diameter of the ring, which is the distance between two opposing points within the ring. To ensure a snug fit, it is important to measure your finger accurately.

The best way to measure your fingers is to go to a jewellery store and have a professional do it for you. If that's not possible, you can also measure your finger at home with a strip of paper or string. Wrap the paper or string around your finger, mark the intersection, and then measure the length to determine your finger's circumference. Then, use the ring size chart to convert the girth to a standard size.

If you're shopping for someone else, it's best to ask them directly for their ring size. If that's not possible, you can also use a ring that they already own and measure the inner diameter or circumference. Keep in mind that ring sizes
