Please be aware that the ring sizes shown on Haggled reflect ring sizes used in the US and Canada. To find your ring size, measure your finger and then use the International Ring Size Chart to convert your size to the corresponding US size.
That is the size you should order. For example, a ring size H in Australia would be a US size 4.
Tips for buying the ring as a surprise
Ask your significant other's friends or mother if they know her ring size. Or when she is not looking, nick a ring from her jewellery stash and use the ring measurements below to determine her size.
Alternatively, download this Ring Sizer PDF and follow the instructions to get your size!
