How to choose the perfect Ring Size?

What is your ring size? Buying rings online can be difficult if you don’t know your ring sizes – frustrating and possibly expensive. Everyone is different, whether it's the size of their fingers or the size of their body. There's no easy way to predict what your ring size might be based on your clothing size or anything else. When you are buying a ring that you will be wearing every day, it is especially important to make sure that the size you select works for you, otherwise you may lose or damage the piece and not be able to wear it comfortably.

When measuring your fingers, keep in mind that they are not all exactly the same size through the day and week. Depending on many factors such as hormones, weather, medication, hydration, and more, your fingers will tend to be larger in the evenings. When your hands are cold, the finger will measure smaller, usually in the morning. 



  • If you have large knuckle, you need to consider that you’ll need the ring to slide over the knuckle. It shouldn’t be too loose that it will slip off or move around easily but is not so tight as to restrict blood flow. You should record both measurements and choose a ring size that’s in-between the two. 
  • Measure the finger you’re intending to wear the ring on. Left-hand and right-hand fingers can differ in size, dominant hand tends to be slightly larger. For example, your ring finger on your right hand may be a 6.5, while the ring finger on your left may be a size 6.  
  • Make sure you measure your finger 3 to 4 times to prevent inaccuracies. 
  • Rings with wider bands (more than 6mm) tend to be more fitting. Do consider getting a quarter or half size larger with a wide band.
