How to Find Your Ring Size at Home: A Simple, Accurate Guide
Quick Answer: To find your ring size at home, wrap a strip of paper or string around the base of your finger, mark where it meets, and measure the length in millimeters. That is your finger's circumference. For example, about 51.9 mm is a US size 6 and about 54.4 mm is a US size 7. Measure at the end of the day, and choose the larger size if you are between two.
Key Takeaways
- The most accurate sizing is at a jeweler; the paper strip method is a close home option.
- US size 6 = about 16.5 mm diameter; size 7 = about 17.3 mm.
- Go up about half a size for wide bands over 6 mm.
A ring that fits perfectly feels comfortable all day and never slips off. The most accurate way to find your size is a professional sizing at a local jeweler, but you can get a very close measurement at home.
Method 1: Measure a Ring You Already Own
Choose a ring that fits the same finger comfortably. Measure the inside diameter straight across, from edge to edge, in millimeters, and match it to the chart below.
Method 2: The String or Paper Strip Method
- Wrap a thin strip of paper or non-stretchy string around the base of your finger.
- Mark where the ends meet. It should be snug but still slide over your knuckle.
- Lay it flat and measure the length in millimeters. This is your finger's circumference.
- Match it to the chart below.

Pro Tips for an Accurate Size
- Measure at the end of the day, when fingers are slightly larger.
- Avoid cold hands. Fingers shrink in the cold and swell in the heat.
- Mind your knuckle. If your knuckle is larger than the base of your finger, choose a size that slides over it.
- Wide bands fit tighter. For bands wider than about 6 mm, consider going up a half size.
- Between sizes? Choose the larger one.
- Measure two or three times to be sure.
