Print the original PDF at actual size, turn off fit-to-page scaling, and measure its calibration mark with a physical ruler. Use a round ring that fits the intended finger, align its inside edge to the guide, and treat the result as an estimate for physical confirmation—not an exact cross-brand size.

Use a printable ring guide only after its physical scale is verified, then keep the result as a reference until the intended finger, band, and fit are checked.

What this guide covers

Print the original file without scaling
Verify the calibration mark
Match the correct existing ring
Confirm the estimate physically

A printable guide is a calibrated estimate

Scale boundary
A page that looks correct on screen may print at a different scale. Do not place a ring on the sheet until the physical calibration mark matches a ruler, and do not treat the printed result as proof of finished-ring comfort.

Choose the usable route

Calibration mark is exact

Continue with a clean, round ring known to fit the exact finger and hand for the new piece.

Calibration mark is wrong

Stop and correct the printer settings. Reprint from the original PDF at actual size rather than stretching the page manually.

No suitable ring is available

Use a physical finger gauge or ask a jeweler to measure instead of guessing from an unrelated ring.

Use the printed circles carefully

Step 1 — Print the original PDF
Select actual size or 100 percent and disable fit, shrink, and page scaling.
Step 2 — Check the ruler mark
Measure the stated calibration line with a physical ruler. A mismatch invalidates the sheet.
Step 3 — Select the right ring
Use a round ring worn comfortably on the intended finger and hand, with a reasonably similar width.
Step 4 — Align the inside edge
Center the ring and find the circle that meets the interior without showing paper inside the opening.
Step 5 — Record and verify
Keep the apparent size and the guide's maker together, then confirm with a physical gauge or jeweler.

Printable sizing questions

Can I use a screenshot of the guide?

No. A screenshot can resize unpredictably. Use the original PDF, print at actual size, and verify its physical scale.

What if the ring falls between two circles?

Record the uncertainty rather than rounding silently. Confirm the fit with a matched physical gauge or jeweler.

Can I use a ring from another finger?

No. The result should come from the exact intended finger and hand, or it is only a weak guess.
