Free printable ring sizer
Print this page, verify the calibration ruler, then measure with the wrap strip or the actual-size circles. No account, no email — just print. Prefer not to print? Use the on-screen sizer or the converter.
① Check the print scale
This line must measure exactly 50 mm (5 cm) with a ruler. If not, reprint at 100%.
② Wrap strip — measure your finger
Cut out the strip, wrap it snugly around the base of your finger, and read the millimeter mark where it overlaps. Match that number below.
③ Or match a ring to a circle (actual size)
Lay a ring you own over the circles. The right size is where the circle sits just inside the band.

Frequently asked questions
How do I use a printable ring sizer?
Print this page at 100% scale (turn off 'fit to page'). Check the calibration ruler with a real ruler — the 50 mm line must measure exactly 50 mm. Then either cut out the wrap strip, wrap it around your finger and read the millimeter mark, or lay a ring you own over the circles and find the one that fits just inside.
Why does my printed sizer look the wrong size?
Your printer scaled the page. In the print dialog set scale to 100% (or 'Actual size') and disable 'Fit to printable area', then reprint and re-check the 50 mm calibration line.
Is a printable ring sizer accurate?
Yes, if printed at 100% and verified against the calibration ruler — that's what the ruler is for. For an engagement ring, still confirm with a jeweler or a physical sizer before ordering.
