Prefer a printable sheet? Download our PDF ring sizing guide, print it, and follow the steps on the page to measure using an existing ring or a simple paper strip.
Printing instructions
- Print on A4 or Letter at 100% (Actual size / No scaling).
- Do not select “Fit to page”.
- Verify the scale on the print-out with a ruler (the guide includes scale markers for accuracy).
How to use the printable guide
- Using an existing ring: place it over the printed circles and match the inner diameter to the closest circle. Read the size label next to it.
- Using a paper strip: wrap a thin strip around the base of your finger, mark where it overlaps, then measure the length and compare to the chart on the guide.
- If your knuckle is significantly larger than the base, measure both and choose a size in between for comfort.
Tips
- Measure at the end of the day when fingers are warm.
- Use a ring you already own and match its inner diameter on the overlay.
- If between sizes, choose the larger size for comfort.
- For a printable option, use the PDF guide above and follow the steps on the page.
