You used to have to mess around with paper printouts, bits of string or go to a jeweller to get your size for an Urban Sterling ring. Nowadays it’s easiest to just order using “Buy now, size later” and have a sizer express posted to your house, usually arriving the next business day.  It’s available for all rings at any time, at no extra cost to you. 

If you have your ring size already in a different sizing system like UK or European, you can use the charts below to convert into US sizing which is what I use.
