How to Measure your Ring Size at Home

There are two easy ways you can measure your ring size right at home so you can finally get your ring measurement right, for good!

Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance. So, there are two details you need to keep in mind:

  • Consider your knuckle. If you know your knuckle is wide, you should order half a size bigger than what your finger alone indicates, otherwise you won’t be able slide a ring into the right place.
  • Ensure accuracy with multiple tries. Size actually fluctuates depending on temperature: It can be smaller the colder you are and more swollen if you’re overheated. Just measure 2 or 3 times before deciding.
Option 1: Use a string
Take a string and wrap it around the base of your finger, marking where the string or floss first overlaps with a pen. Then, line that up with a ruler and take down its length in millimeters.

Option 2: Measure a ring you already own
Place your ring on top of a ruler and measure the inside diameter. Make sure  the alignment with the ruler is ok since you really want to measure the inside-to-inside spacing in the middle part of the ring.
