Print it out, grab a ring that fits, and use the circles below to find your perfect size. No guessing—just real, straightforward sizing that works.
Print Scale Check
Place a real ruler against the line below. It should measure exactly 5 cm (50 mm). If it doesn't, reprint at 100% scale.

Place a ring that already fits you over the circles. The correct size is the one where the inner edge of your ring lines up exactly with the black circle line.

How to Measure Your Finger at Home
Step 1 – Wrap
Cut a thin strip of paper or use a piece of string. Wrap it around the base of the finger you want to measure.
Step 2 – Mark
Mark where the paper or string overlaps.
Step 3 – Measure
Lay it flat and measure the length in millimeters. This is your finger's circumference.
Step 4 – Match
Use the chart above to find the closest circumference and corresponding US size.
Tips for Accuracy
- Measure at the end of the day when your fingers are warm.
- Measure the same finger 2–3 times for accuracy.
- If you're between sizes, choose the larger size for comfort.
