MEASURE YOU FINGER
Step 1:
Take either a length of string or floss and wrap around your finger. At the place where it overlaps, mark the point with a pen.
Step 2:
Unwrap it and lie it flat beside a ruler or measuring tape. Measure circumference of your finger in inches or mm.
Step 3:
Enter the resulting value below in the field.
Make sure you don't pull the thread or string too tightly, as it can be stretchy and then it may seem that you need a bigger ring size than you actually require.
Enter the result in millimeters / inches
Your ring size:
MEASURE EXISTING RING
Step 1:
Select an existing ring that fits the desired finger.
Step 2:
Measure the internal diameter of the ring (in inches or mm).
Step 3:
Enter the resulting value below in the field.
Make sure you compare the internal diameter, not the outer part of the ring.
Enter the result in millimeters / inches
