Did you know there are several ring size systems in use around the world?
Australia, the United Kingdom, Ireland, New Zealand and South Africa share a system based on the alphabet (sizes A - Z+6) while the United States, Canada and Mexico use a numerical system (sizes 1-16).
Europe and Asia also have their own systems.
We take orders for rings in our online jewellery store in both the Australian/British letter system and the North American number system.
Before ordering, you'll need to make sure you know you know your ring size. There are a couple of important things to bear in mind:
- wider rings require a larger size
- our right and left hands are usually not the same size
Wide Band Rings
If the ring you're purchasing is wider than 4mm for women or 6mm for men, you'll need a larger size than usual. Wide band sizes are usually about 1/2 size larger in the US system and a full size larger in the Australian/UK system but it is best to have them measured professionally if possible as this won't be accurate for everyone. Our product pages will mention if a wide band size is required.
Your Dominant Hand Will Be Larger
While your hands might look the same size, your dominant hand is usually slightly larger, ie if you're right-handed, your right ring finger will be slightly larger than your left ring finger and vice versa. It's best to decide which finger you're going to wear a ring on before measuring.
How To Find Your Ring Size
Sizing rings can be tricky and there are a few ways to do it. We'll start with the most accurate and then describe some that can be done at home but will most likely be less accurate.

Have your ring size measured professionally
If you are near a brick-and-mortar jewellery store, you can ask them to measure your ring size. This is the best and most accurate way to have your ring size measured. They should do it free of charge and you'll know the size is correct. Don't forget that if you're purchasing a wide band ring, you'll need to ask them to measure your wide band size.

Use an existing ring
You'll need a pair of vernier, dial or digital callipers and a ring that fits your finger for this method.
Zero the callipers and measure the internal diameter (straight across) of your ring, making sure you measure at the widest spot. Note this measurement and use our international ring size conversion chart to find your size. Use either the first or second column (inches or mm) and find the size closest to your size, then scroll across to find your corresponding Australian/British or North American ring size.
If you fall between two sizes, unless very close to the smaller size, we recommend going up a size rather than down.

Purchase one of our ring sizers
We sell plastic, reusable US ring sizers in our online store. These sizers come with instructions and are easy to use. They are not as accurate as professional sizers but they are a good alternative if you are unable to visit a local jewellery store.
They cost AU$6, including postage within Australia.

Measure your finger with a piece of paper
Please be aware that this is the least accurate method and comes with a high chance that the size will be wrong. Wrap a narrow piece of paper (4 or 5mm wide) around your finger. It shouldn't be too tight but not so loose that it would fall off if it were a real ring. Mark the spot where the two ends meet and measure the length of the piece of paper in millimetres.
Use our international ring size conversion chart to determine your size.
