With the help of the internet, you can access almost anything right from your fingertips. The same is true when it comes to measuring your ring size. Whether you’re treating yourself just because or buying a ring for that special someone, we have three no-fail ways for you to measure your ring size at home.

U.S. ring sizes are determined by a scale of numbers and half numbers, usually between sizes 3 and 13.5 for adults. Each ring size matches the width of your finger in millimeters. Women’s rings are usually between 3 and 9, but men’s rings are sized between 8 and 14.

Ring Sizing Tips:

  • Measure your ring size in the morning when your body is cool. This way, swelling won’t affect the measurement. 
  • Make sure you measure the finger you are going to wear your ring on. 
  • A wider band means a tighter fit. Consider allowing some wiggle room.
  • Larger knuckles can make sizing a little bit tricky. Find a ring size that will allow you to easily slip the ring over your knuckles but isn’t loose enough to fall off. 

We know you’re excited to show off your ring bling! Whether you are treating yourself or buying for someone you love, our ring sizing tips will make sure that ring fits perfectly.
