Estimating Your Ring Size
For those interested in purchasing a ring but unsure of your ring size, here is a method of estimating your size (or how to determine your approximate US ring size if you know your size in a different measurement) without need for special tools.
1) Cut a strip of paper not wider than 1/4".
2) Wrap the paper snugly around the base of your finger and mark the paper where it meets.
3) Measure the marked length of paper and compare it to the chart below.
*Please Note: If your knuckle is significantly larger than the base of your finger, measure your knuckle using the method described above and choose a ring size in between the two measurements.
