Three sheets: a paper ring sizer you cut out, a circle chart for a ring you already own, and the full conversion table. Choose your paper and download.
Ring size chart printable: what is on the three sheets
- The paper ring sizer. Six strips, so you can cut a fresh one if the first tears. Each has a slot, a scale marked every millimetre of circumference, and the size printed at each whole size.
- The circle chart. Circles at every half size. Put a ring you already wear over them and find the circle whose line just disappears under the band.
- The conversion chart. US, UK, EU/ISO, Japanese 号, China/Hong Kong, India, Italy/Spain/Switzerland, diameter and circumference, in one table you can keep in a drawer.
Print it at the right size, or it is worse than useless
This is the part that goes wrong. Browsers and print drivers love to shrink a page a few per cent to keep clear of the printer’s unprintable margin, and a sizer printed 4 % small reads a whole size too small. Nothing on the sheet tells you it happened — the strip still looks like a ring sizer.
So every sheet of this PDF carries two checks you can do with things you already have:
- A 50 mm line. Put a real ruler on it. If it is not 50 mm, the sheet printed at the wrong scale — do not cut it out.
- A bank-card outline. Every payment, ID and loyalty card in the world is ISO/IEC 7810 ID-1, exactly 85.6 × 53.98 mm. Lay a card on the outline; it must sit inside it exactly, with no white showing and no overhang.
Printer settings that work
| Where | Setting | Must be |
|---|---|---|
| Chrome, Edge | More settings → Scale | Default, or Custom 100 — not "Fit to printable area" |
| Firefox | Scale | 100 % — untick "Shrink to fit page width" |
| Safari / macOS | Scale | 100 % — not "Scale to fit" |
| Adobe Acrobat Reader | Page Sizing & Handling | "Actual size" — not "Fit" or "Shrink oversized pages" |
| Phone (iOS / Android) | — | Phone print dialogs often scale silently. Print from a computer if you can, and check the 50 mm line either way. |
Plain paper is fine. Card stock makes a sturdier strip but some printers feed it short — check the 50 mm line again if you change paper.
Using the paper sizer
- Cut out one strip along the outline, then cut the short slot open with the tip of a knife or the point of your scissors.
- Wrap it round the base of the finger with the numbers facing out.
- Feed the tail through the slot and pull until it is snug — firm, but it must still slide over the knuckle.
- Read the number at the arrow. If it sits between two marks, take the larger.
- Do it twice, warm hands, at the end of the day. If the two readings differ, take the larger.
If you cannot print
Use string or a strip of paper and a ruler, or measure a ring you own on the screen after calibrating it with a bank card. Neither needs a printer, and the string method is more accurate than a badly printed sizer.
Questions people ask
Is the printable ring size chart free?
Yes. No account, no email, no watermark. The PDF is built in your browser, so nothing you do here reaches a server.
A4 or Letter?
Pick whichever your printer is loaded with. The drawing is identical on both — only the sheet around it changes — so an A4 sheet and a Letter sheet give the same sizes.
How do I know the print came out at the right scale?
Measure the 50 mm line with a ruler and lay a bank card on the card outline. The card is 85.6 × 53.98 mm by international standard, so if it fits the outline exactly the whole sheet is at 100 %.
Can I print it on a phone?
You can, but phone print dialogs scale pages without telling you. Check the 50 mm line before you cut, and if it is wrong, print from a computer instead.
Can a jeweller use these sheets in a shop?
Yes, print as many as you like. A paper sizer is still a paper sizer, though — for a ring that cannot be resized, measure on a steel mandrel.
