Ring sizer — print at 100% scale

Place a ring that already fits over the circles until the inside edge of the band matches a circle exactly.

Calibration bar: this must measure exactly 100 mm (10 cm) on paper. If it does not, reprint with scaling set to 100%.

Finger measuring strip

Cut along the dotted line, wrap the strip around the base of your finger and read the millimetre mark at the overlap. That number is your inside circumference.

How to print it accurately

Open the downloaded PDF in a proper PDF reader rather than a phone preview.
In the print dialog set Scale to 100% or Actual size. Turn off “Fit to page” and “Shrink oversized pages”.
Print on A4 or US Letter paper — both work, the artwork is centred for each.
Measure the calibration bar with a ruler. Exactly 100 mm means the scale is right; any other value means the print was resized.
Only then use the circles or the cut-out strip to measure.

Tips for an accurate result

Fingers change size through the day. Measure in the late afternoon or evening, when your hands are at their warmest, and never straight after exercise or a cold walk — a cold finger can read a full size smaller.

Measure the exact finger the ring is for, on the correct hand: most people's dominant hand is around a quarter to half a size larger. If your knuckle is noticeably wider than the base of the finger, choose the size that slides over the knuckle with gentle resistance.

Wide bands sit tighter than thin ones. For any band over about 6 mm wide, go up a quarter to a half size. For more detail, read our measuring and fit guides.
