Ring Size Guide

We use generic US sizes, see below how to find or convert your size if you do not know your US size.

To find your size you can use a few different methods:

You have a ring and want to know which size it is. 

Option 1)  If you already have a ring that fits you, you can download the app Ring Sizer by Jason Withers and follow instructions, it will tell you your size also in US sizes.

Option 2)  You can also use a ruler and a ring you havre already that fits you. To measure with a ruler, you need to measure the innner sides of your ring, place the ruler on a flat surface and place your ring on top and place the left inner side at 0 on the ruler. Read where the inner right side of your ring starts. This is your ring size in mm.

3) Use guide below to use the mm and find your equivalent size. Eg if you have measured your ring to be 16,5mm across then your US size is a size 6. 

You do not have a ring and want to know which size to purchase:

Option 1) You can print out the ring sizer guide below with the ring sizer to cut out and wrap around the finger you wish to wear your ring then read what number it states where the ends meet.

Option 2) You can cut a strip of paper and make wrap it around your finger as close to you knuckles as possible, then use a marker and draw a line where the paper meets then use a ruler to measure that distance of the points. Eg measure this to be 60mm. Use the conversion below and use the German table to find 60mm and then go to the US which reads a US size 9. If you neede the size in UK, go to Germany 60mm and find UK, then read the number on the sameline as 60mm, which is a UK size R. 

If needed, we can make a custom size for you for a fee, if you need this service please do email us at: info@ooikos.dk.
