This guide will help you to find the ring size you need. All you need is a piece of thread, a ruler and a marker. 

Measure your finger:
Measure your ring size with a thread, a ruler and a marker. Take your thread and wrap it around your finger two times. Be careful not to wrap the thread too tight. Use your marker to mark where the thread crosses on your finger. Take the thread off your finger and let the marks meet to make a circle. Use your ruler to measure the diameter of the circle. Use the diameter to find your ring size here. If you happen to be in between sizes, we recommend choosing the bigger size.

Measure your ring:
You can also measure your ring size from a ring that fits you, using a ruler. Place your ring on top of your ruler to measure its diameter from the inside of the ring shank. Use the diameter to find your ring size here. If you happen to be in between sizes, we recommend choosing the bigger size.

Remember that your fingers will slightly change sizes according to temperature. During warm weather, they will be a bit thicker and during cold weather, they will be slightly thinner. If the ring you want has a thicker ring shank, we recommend sizing up.
