men's jewellery - ring size chart
All gifts for blokes rings are measured using the inside ring measure in mm.
If you already have a ring then simply measure the inside of it with a ruler to get your size. (using mm)
If you dont have a ring then using a piece of string or strip of paper, wrap this around your finger and mark with a pen where the paper meets.
Then measure the distance between the start of the paper and the pen mark and this will give you the circumference measurement in mm.
Then use our chart below to assist you in locating your ring size.
