Printable ring sizer FAQ
Is a printable ring sizer accurate?
It can be accurate if you print at 100% scale and verify calibration with the ruler line and card-size reference box before measuring.
How do I print the ring sizer correctly?
Use the print button, select A4 or US Letter, and disable Fit, Shrink, or Scale to printable area. Keep scaling at 100% or Actual Size.
What if the printed ruler is not exact?
Reprint with scaling options off and verify again. If the ruler still does not match, try another browser print dialog.
Should I use the circles or the strip sizer?
Use circles for an existing ring and the strip for finger measurement. Compare both results if possible for higher confidence.
How can I confirm my final ring size?
Cross-check your result with the ring size chart, then verify with the converter or calculator using millimeter values.
