Ring Sizing Guide

BY: Editorial Staff | Jun 24, 2016

If a ring is too small it won't fit over your knuckle, and if it's too big it won't stay on your finger when you start to slow clap after a dog wins a basketball tournament. Find your ring size using one of the following methods:

String and Ruler Method (No Printer Required)

Supplies Needed

  • Ruler with millimeter measurements
  • Non-stretchy string or a strip of paper


  1. Wrap a piece of non-stretchy string or strip of paper around the base of your finger
  2. Mark the point where it overlaps using a pen or fine-point marker
  3. Measure the length in millimeters using a ruler
  4. Compare the length to the ring-size chart below to determine your ring size


Size Length
Size 5 49 mm
Size 6 51.5 mm
Size 7 54 mm
Size 8 56.5 mm
Size 9 59.1 mm
Size 10 61.6 mm
Size 11 64.1 mm
Size 12 66.6 mm
Size 13 69.1 mm


Measuring Tips

  • All measurements match the inside circumference of the ring
  • If your finger measurement falls between sizes, order the larger size.
  • Fingers, like brains, are smaller in the morning and bigger by the end of the day. Measure your fingers at the end of the day.
  • Take multiple measurements to ensure an accurate reading.
  • Weather and temperature affect finger size. Do these measurements where it's moderately warm.
  • If you have large knuckles, measure both the base of your finger and your knuckle and select a size between the two.
  • Fingers tend to be one half-size larger on your dominant hand

Diagram Method (Printer Required)
