Do you know your ring size?
It's interesting to know that it's common that many people don't know their ring size when purchasing a ring.
Well I am here to help.
I generally recommend two ways to size your finger.
- Measure the inside diameter of a ring you currently have against a ruler.
- Find a piece of string wrap it around your finger and measure that against a rule
If you are planning to get a thicker ring regardless of what people might say it's best to stick to the measurements above and the jeweler will figure it out.
Like a clothing size, there are different sizes for different regions. If you do know your size you can find your comparative size below.
Alternatively, if you measure you finger size by either of the methods above you can compare you insider diameter size in the chart below.
For example, I have measured my index finger with a piece of sting and it was XX mm in length. This is your inside diameter. If I look at the chart below this means I would be between XX and XX size.
Below is a table:
