Ring Sizing Chart With Guide
Do you know your ring size? Finger sizes vary significantly from one person to the next, so it can be almost impossible to get your ring size right just by guessing. Use our ring sizing chart and guide to check your ring size before before buying rings online.
How Should a Ring Fit?
Ultimately this comes down to what feels comfortable. But as a guide, your ring should fit your finger well enough so it won't fall off, but it should also be loose enough to fit over your knuckle without too much difficulty - and allow for natural changes in finger size that happen throughout the day.
Should You Go Larger or Smaller?
Your ring should fit your finger well enough so it won't fall off, but it should also be loose enough to be comfortable and fit over your knuckle without too much difficulty - and to accommodate for changes in finger size each day.
If you're between ring sizes or there's a reasonable difference in your size throughout the day, a good thing to bear in mind is that it's always better to go for a slightly larger size than one that's too small, so you should err in that direction. There's nothing worse than a ring that's too tight on your finger.
Wide Band Rings
If you're purchasing a ring with a wide band (8mm), this will require a larger size. You should go up a quarter to half a size using US numerical sizes or a full size in the Australian and British alphabetical ring sizing system. Refer to our ring sizing chart below for more help.
Large Knuckles
If you have larger knuckles, don't forget that you'll need the ring to slide over your knuckle without too much difficulty. Larger knuckles commonly occur for those who have arthritis in their finger joints, so take particular care with measuring your ring size if that's the case.
To take this into account, you should also measure your knuckle and the part of your finger where the ring will sit. Choose a size between your finger size and knuckle size and check to be sure that a ring that size will fit over your knuckle.
