A printable sizer is only as trustworthy as its scale. Use the exact file, print at one hundred percent with fit-to-page disabled, verify the calibration mark with a physical ruler or named object, then follow one method and repeat it.

A printable ring-sizer specification built around exact file version, one-hundred-percent printing, physical calibration, separate finger and existing-ring methods, repeated checks, and professional confirmation.

What this guide covers

Open the exact versioned asset and use its stated paper size and print controls.
Measure the calibration mark before placing the strip on a finger or a ring on the chart.
Repeat the reading and confirm the exact finger and intended width professionally before ordering.

Prove the page scale before measuring

If any print or calibration check fails, stop; a clean-looking page can still be the wrong physical size.

Use the canonical PDF version and the paper size printed on that file, not a screenshot, preview image, or copied crop.
Choose actual size or one hundred percent and disable fit-to-page, shrink, enlarge, borderless scaling, and automatic page conversion.
Measure the printed calibration line with a physical ruler or compare the named reference object in both directions.
Do not use a strip with a damaged slot, stretched paper, soft fold, unclear edge, or a calibration result outside the stated tolerance.
Keep finger-wrap and existing-ring chart methods separate and record which one produced each reading.

Use one calibrated method at a time

The asset should teach a reproducible home estimate while making its limits impossible to miss.

Calibrate — Check the physical reference
Measure the reference after printing. If it fails, adjust the print setup or use another printer; never compensate by guessing at the ring reading.
Measure — Follow the selected diagram exactly
Wrap the strip without stretching and allow joint passage, or center a perfectly round, well-fitting ring over the matching inside circle.
Confirm — Repeat under comparable conditions
Take more than one reading, note material disagreement, and use a professional gauge on the exact finger with a similar band width.

A printable asset remains a home estimate

Print boundary
This guide does not provide a downloadable file or verify a printer's scale. A calibrated paper reading still cannot resolve joint shape, temperature changes, wide bands, unusual geometry, comfort, resizing, or production. If the scale, ring, strip, or readings are uncertain, use professional sizing.

Printable-sizer questions

Can I measure the sizer on my phone screen?

No. Screen size, zoom, device scaling, and screenshots are not controlled by the print calibration. Use the exact printed asset and verify its physical reference.

What if two home readings disagree?

Do not average them blindly. Recheck scale and technique, then have the exact finger measured professionally, especially for a wide, valuable, unusual, or hard-to-resize ring.
