A printable ring size chart is one of the most commonly searched ring sizing tools, and for good reason: it feels like a fast, free way to check your size at home. The catch is that almost every printable or PDF ring sizer has the same flaw — most browsers and printers automatically rescale a page to "fit" the paper, which quietly shrinks or stretches the chart. A chart that is even 5% off scale can push your result a full size in the wrong direction.
Below is a printable chart with actual-size ring circles and a built-in scale check, so you can confirm your printout is accurate before you trust it. We also cover a second option that skips printing altogether and is usually more reliable, since it calibrates to your exact screen instead of hoping your printer didn't rescale the page.
Step 1: Print This Chart at the Correct Scale
Before printing, open your browser's print dialog and look for a scale setting. Set it to 100% or "Actual Size" — never "Fit to page" or "Shrink to fit," since those options are exactly what distorts the measurement.
Every printer and browser handles scaling slightly differently, so do not assume 100% actually means 100%. Use the calibration line below to check before you compare a ring against the actual-size circles.
Scale check
After printing, measure this line with a ruler. It should be exactly 50mm long.
If it measures anything other than 50mm, your print scale is off — reprint at 100%/Actual Size, or use the screen-calibrated tool further down this page instead.
Actual-size ring circles
Once the scale check above measures exactly 50mm, place a ring you own flat on top of each circle. The circle whose inner edge matches the ring's inner edge is your size.

Falls between two circles, or need a size outside US 5–11? Use the full table below, or the screen-calibrated tool for any size without a printer.

Why Printable Charts Are Risky — Even When You Print at 100%
The scale check above catches the most common problem, but it does not catch every source of error. Paper can shrink or stretch slightly with humidity, home printers vary in mechanical precision, and PDF viewers sometimes apply their own default scaling before the print dialog even opens. None of that shows up until you compare a ring against the printed chart and get an answer that is subtly wrong.
This is also why we deliberately did not build this site around a printable PDF. Every "actual size" PDF ring sizer has this exact weakness, which is the reason ring sizes measured at home so often disagree with a jeweler's metal sizing ring.
A More Reliable Option: Skip the Printer Entirely
Instead of trusting a printer to reproduce a scale accurately, our screen-calibrated ring sizer calibrates directly to your device using a real bank card as the reference object. Since a bank card's dimensions are standardized worldwide (53.98mm), the calibration corrects for your specific screen's pixel density — no printer, no paper shrinkage, no guessing whether "100%" actually meant 100%.
Once calibrated, you can match the on-screen circle against a ring you already own, or use the string/paper circumference method and enter the number directly, both of which are covered on the calculator page along with full US, UK, EU, India, Japan, China, and Australia conversions.
FAQ
Is a printable ring size chart accurate?
Only if it prints at exactly the intended scale, which is not guaranteed. Browsers and printers often rescale pages by default to fit the paper, which shrinks or stretches the chart just enough to throw off your result. Always print at 100%/"Actual Size" and verify with a ruler using a known reference length before trusting the chart.
How do I print a ring size chart at the correct size?
In your browser's print dialog, set the scale to 100% or "Actual Size," and disable any "Fit to page" or "Shrink to fit" option. After printing, measure a known reference line on the page with a ruler to confirm the scale is correct before using the chart.
What if I do not have a printer?
Use a screen-calibrated ring sizer instead. Our free tool calibrates to your exact device using a bank card as a reference object, then lets you match an on-screen circle to a ring you own or enter a string/paper circumference measurement directly — no printing required.
Why does my printed ring size chart not match my actual size?
The most common cause is print scaling. If the chart was printed smaller or larger than intended, every measurement on it shifts by the same percentage, which can be enough to change your result by a full size. Paper shrinkage from humidity and printer mechanical variance can also contribute smaller errors.
Can I trust an actual-size ring size chart from a PDF?
Only after verifying the print scale yourself. A PDF being labeled "actual size" does not guarantee your specific printer and PDF viewer combination reproduced it at that scale. Always check a known reference length with a ruler after printing, regardless of what the PDF claims.
