Size Guide

Ring Size

To determine your ring size tredici.zerodue jewels proposes you 2 methods:

1. Take measurements of your finger circumference manually.
Cut a thin strip of paper or get yourself a piece of string of several centimeters or use a tailor’s tape.
Wrap the tape, string or strip of paper around your finger. Make sure that the chosen size leaves enough room for the ring to pass easily along the entire length of the finger.
Do not tighten the strip too hard when you wrap around your finger. The strip should slide easily. Mark with a pen where the strip joins.
Unroll the tape and measure in centimeter the length between the two pen marks using a ruler. Check the chart below

 

Your should rather measure your finger at the end of the day, when the temperature is higher. This is when your finger is most swollen. This prevents from choosing a ring that is too small!
Remember that the two hands differ slightly in size; a ring worn on a finger of the left hand will not be a perfect fit for the same finger on the right hand.

2. Measure the size of one of your ring with a ruler.
Measure the inside diameter of one of your rings with a ruler, note the centimeters.
Check the chart below to find out your size.

If you are hesitating between two sizes, choose the larger size.
Please note that the style of the ring will also affect the size choice:
tredici.zerodue jewels open rings are fully adjustable and they are made to be worn more loosely that a closed model.
