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.
Cut a strip of paper no wider than 1/4" .
Wrap the paper snugly around the base of your finger and mark the paper where it meets.
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.
