If you don't know your ring size, we would recommend buying a ring sizer online, they aren't expensive and can be very helpful. If you don't want to do that, below are some handy tips for finding your finger size.
​
It's best to measure your finger's size in the evening. Your fingers can change size a lot during the day and it's always best to choose the larger measurement - if your fingers are cold you can be a half size smaller than usual!
​
You're ring should be snug, but loose enough for the ring to pass over your knuckle. Too tight and it's going to be uncomfortable, too loose and it could fall off!
​
You can probably comfortably fit one or two sizes on one finger as the difference is fairly small. If the ring has a thick design, it is best to go up a size so you can easily flex your finger, if it is more delicate we recommend you have a more snug fit as it may feel looser.
​
Use a ring that already fits your finger to check your size. This is probably the easiest option, you can draw around the inside of the ring on some paper to find the size. Don't forget that your dominant hand will likely have bigger fingers, so make sure you test the right one!
​
Use a piece of string or paper to measure around your finger and check the length on a ruler. This can be a fiddly job and you may need someone to help you. The list below should then help to determine the size.
