Alternatively, you can measure the internal diameter of a ring you already wear on the same finger and compare it with our size guide.

Disable “fit to page” or any resizing options before printing.

Once printed, place your ring over the circles: the correct size is the one where the inner edge aligns perfectly. You may also use the table below to determine your size based on the ring’s inner diameter.

If you don't have a ring to measure, you can estimate your size using a strip of paper. Here's how:

1. Cut a strip of paper and wrap it around the base of your finger, just below the knuckle. Ensure the fit is snug but not too tight.
2. Mark the point where the paper overlaps, then measure the length of the strip with a ruler.
3. Refer to our circumference conversion chart to find your size.

Please note, while the paper strip method provides a good estimate, measuring a ring you already wear will offer the most accurate result.
