Printable ring sizer
Print this page at 100% scale for a free, accurate paper ring sizer. Check it against a bank card first, then use the true-size circles or the wrap strip.
1 · Scale check
The box below should be exactly the size of a bank card (85.6 × 53.98 mm). If it isn’t, fix your print scale to 100%.
2 · True-size circles
Rest a ring you own over the circles until the inside edges line up. Read the label.
3 · Finger wrap strip
Cut out the strip, wrap it around the base of your finger, and read where the end meets the scale (marked in circumference mm).
Scale starts at 44 mm circumference. Numbers are US sizes.
Frequently asked questions
How do I print a ring sizer at the correct size?
In the print dialog set Scale to 100% (or "Actual size") and turn OFF "Fit to page". Then check the printed card outline against a real bank card, if it matches, every circle and mark is true to size.
How do I use the printed circles?
Place a ring you already own over the circles until you find the one whose inside matches the ring’s inner edge. The label on that circle is your size.
How do I use the wrap strip?
Cut out the strip, wrap it snugly around the base of your finger, and read the size where the end meets the scale. Measure at the end of the day when fingers are largest.
