Ring Sizing

Ring sizing can be tricky when ordering online, but it doesn't have to be. If you can't get to a jewelry counter to be sized, here are a few tips you can use to measure yourself for a perfect fit.

Measure a ring that you already own. Choose a ring that properly fits your intended finger. Take a ruler, or measuring tape, and measure across the widest part of the inside of the ring. Don't measure to the outside of the band, just the inner circle. This will give you the diameter; it is generally measured in millimeters. Note - if your ring measurement falls in between, you'll want to size up. If it's too small, it may not go on and/or can get stuck on your finger. Ouch!

Measure your finger.* You want your ring to fit comfortably. It needs to be snug enough that it won't fall off, but loose enough so that it can pass over your knuckle. Your fingers change size throughout the day, believe it or not! For best results, you should measure your fingers when your hands are warm, and toward the end of your day. Your fingers tend to be smaller in the early morning or when they're cold. To measure, you will need:

  • A thin strip of paper - about 2-4mm wide, depending on the width of the band on the ring you'd like to purchase. If you have thicker card stock or photo paper, this would be better as it's sturdier than regular copy paper.
  • Measuring tape - remember it needs to be in millimeters. (10mm=1cm)

Wrap the paper strip around your finger, making sure it is loose enough that it can pass over your knuckle (super important!) comfortably. Mark with a pencil/pen where the paper overlaps to form a circle. Lay the paper piece flat and measure to your mark to find the circumference of your finger. *Measure 3-4 times for accuracy.

Use the chart below to find either the diameter or circumference, depending on which method you chose, and the corresponding US Ring Size number. This chart has only the average range of sizes I carry and create in my shop, if you need a special size do not hesitate to message me.
