RING SIZE GUIDE
Our experts have put together their top tips and answers to the most commonly asked questions, including the average ring sizes for both men and women, to help you figure out the best solution to finding the right ring size for your partner, or for yourself!

How to find your ring size
Whether browsing for your own wedding ring or planning a surprise proposal, getting the ring size right is important to ensure a lifetime of comfort. In order to find the most accurate ring size, it’s best to book an appointment with an expert to have your finger measured. That said, this isn’t always possible or practical - particularly if you’re planning something special for your partner.
With a team of experts at Gear Jewellers, we’ll take you through the average ring sizes for both men and women in regards to engagement ring sizes and wedding rings sizes, and reveal the super effective way our consultants estimate the ring sizes of those they’re unable to measure.

Ireland Ring Sizing Chart
Use our ring size chart and compare the diameter of a perfectly fitting ring with its ring size. To find your ring size, measure the diameter of a ring that fits the finger you'd like to find the size of. Note that your ring finger will measure differently to your other fingers, and could even be smaller or larger than the same finger on your other hand!
You may also be able to use a flexible measuring tape. Ensure this would sit securely behind your knuckle but not too tight or loose; you should be able to take it off your finger with a couple of twists.
You can also download our printable ring sizer to help you find the best ring size for your ring.
