Ring Sizing Guide – How to Measure Your Ring Size Accurately
Finding the right ring size is essential when purchasing fine, handmade jewelry, especially one-of-a-kind pieces that may not be resizable. Use this simple guide to measure your ring size at home and shop with confidence at Faust Gallery.
How to Measure Your Ring Size at Home
You can determine your ring size in a few easy ways using common items or by measuring a ring you already own.
Option 1: Measure Your Finger with a Strip of Paper or String
What you’ll need: a thin strip of paper, a ruler (millimeters), and a pen.
- Wrap the paper around the base of the finger where you’ll wear the ring.
- Mark the point where the ends overlap.
- Measure the length (in millimeters) with a ruler—this is your finger’s circumference.
- Use the chart below to find your U.S. ring size.
Tip: The paper should fit snugly but still be able to slide over your knuckle.
Option 2: Measure a Ring That Fits You
What you’ll need: a ring that fits the intended finger and a millimeter ruler or caliper.
- Place the ring on a flat surface.
- Measure the inside diameter straight across the center in millimeters.
- Compare that number to the chart below.

Ring Sizing Tips for the Best Fit
- Measure at the end of the day – your fingers naturally swell and shrink.
- Avoid measuring cold hands – cold temperatures cause fingers to contract.
- Wider bands fit more snugly – consider sizing up ¼ to ½ size for rings wider than 6mm.
- Your dominant hand may be larger – double-check if you’re switching hands.
- If you’re in between sizes, it’s safer to go up a half size.
Can Rings Be Resized?
Many of the rings at Faust Gallery are handmade by renowned Native American and contemporary jewelers using inlay, stone settings, or tufa cast techniques. Some of the designs are often not resizable due to their intricate construction. We always recommend measuring accurately before purchasing.
