Kick in the Eye uses Australian & UK standard Alphabetical ring sizing. See the International Ring Size Conversion Chart here.
To find your size with the most accurate outcome we recommend having your fingers sized at any jewellery store in person - this is a free service.
Ring Sizers are available to purchase through this product listing. 
DIY methods are not recommended as the inaccuracy usually results in resizing - every millimetre makes a difference! However, if you wish to do it at home the best way is to measure the inside diameter of a ring that already fits on the desired finger, then match the dimensions to the conversion chart listed above.
The average female finger size is an 'O' and a 'U' is the average for men.
A ring resize fee is $30, plus the return tracked shipping fee ($10 Australia / $25 worldwide). The customer will be responsible for sending the jewellery to the maker in the same state as it was received in. The turn around time is 2 weeks from when the ring is delivered back to the maker. Please email to organise this.
