If you know your ring size in one of the systems, just look it up in the ring size chart below and find the corresponding ring size in a different system.
If you don't know your ring size
The easiest way to find out your ring size is to measure the circumference of your finger and then find the corresponding size using the ring size chart. To measure the circumference, wrap a ribbon or a string once around your finger. Then measure length of the portion that went around the finger - that is the circumference of your finger.
Remember that the ring will have to go past your knuckle so allow a bit of leeway. Also, make sure that you do not wrap the string or ribbon too tightly - rings are hard to enjoy when they cut off your blood circulation!
To find out your girlfriend's/wife's ring size
That romantic valentine's day gift works best as a surprise and asking "what's your ring size, dear?" may be a bit of a giveaway. So here are some hints for finding out her ring size without spoiling the surprise:
- If she has a few rings that she does not always wear or takes off rings for shower etc - take a ring and measure its diameter. Then use the ring size chart to arrive at the size.
- Put one of her rings on your finger, mark the spot where it fits, then use the ribbon or string to measure the circumference at that point.
- If she is not likely to notice, take one of her rings to a jewellery store and ask for the size (you might have to deal with a salesperson trying to sell you half the rings in the store, though).
- If she is a deep sleeper - use the string or ribbon to measure her finger while she is sleeping.
- If she has a friend, sister, mother, etc who you can trust to keep a secret - ask them.
If all else fails, you can get a ring re-sized if it is sterling gold or silver. Plated rings cannot be resized. Silver rings are harder to resize than gold rings (because silver is such an efficient heat conductor). Also, remember that rings with some gemstones are harder to resize than others.
