There are numerous factors that affect ring size besides actual finger measurement. Firstly most rings are perfectly round, although fingers are not. Secondly, the difference in size between finger joints and the place where a ring sits also affects the choice of ring size. Third, fingers change size in response to body chemistry and temperature, sometimes by several sizes. The size that is chosen is also affected by the specific ring. Wider rings and those in which a stone or setting projects toward the finger will require larger sizes than thinner rings, even for the same finger. Often, the best way to determine ring size is to go to a jeweller for a fitting. Keeping this in mind, here is a method to help you determine your approximate ring size and a table showing the conversions between AUSTRALIAN and US sizing.
DETERMINING YOUR RING SIZE
- Cut a strip of paper or string about 10cm long and about 2cm wide (or use our downloadable ruler).
- Wrap the paper strip or piece of string around the widest part of the appropriate finger to measure the circumference. Often, this will be at a joint, but it may be in a number of locations and maybe different for each of your hands. You can use an old ring to help find the widest spot.
- Use a pen or pencil to mark the point on the paper where the ends of the paper strip overlap (form a complete circle). If you are using a piece of string simply cut the string where the ends overlap.
- Use a ruler to measure the length to the nearest millimetre, rounding up if necessary.
- Find the closest measurement on the size chart to determine your ring size.
