HOW TO FIND YOUR RING SIZE
Here are two ways to do it – measure the circumference of your finger or internal diameter of the existing ring.
MEASURE YOU FINGER
- Step 1: Take either a length of string or floss and wrap around your finger. At the place where it overlaps, tie a knot.
- 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: Use the below chart to determine your ring size.
- Tip: 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.
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: Use the below chart to determine your ring size.
- Tip: make sure you compare the internal diameter, not the outer part of the ring.
Internal Diameter of the Ring (mm) | 15.3 | 15.7 | 16.1 | 16.5 | 16.9 | 17.4 | 17.8 | 18.2 |
Circumference of the Finger (mm) |
47.9 | 49.3 | 50.6 | 51.8 | 53.1 | 54.5 | 55.7 | 57.1 |
USA | 4½ | 5 | 5½ | 6 | 6½ | 7 | 7½ | 8 |
