Choosing rhinestones for a project often starts with two different measurements: an SS number from a seller and a diameter in millimeters.
This printable rhinestone size chart puts those systems together so you can compare stones, check listings, and plan layouts with a clearer sense of scale.
The five-page black-and-white PDF includes actual-size comparison circles, an SS-to-millimeter table, calibration bars, and a measurement log.
It covers round rhinestones from SS3 through SS50, with additional millimeter circles from 1 to 12 mm for stones without a visible size label.

About This Printable
SS stands for Stone Size, but each SS number represents a diameter range rather than one universal measurement.
The chart shows those ranges beside midpoint-based circles, helping you see how neighboring sizes compare while keeping the limits of printed references clear.
The first two pages divide the range into smaller sizes from SS3 to SS20 and medium-to-large sizes from SS21 to SS50. This split keeps the circles readable and gives each label enough room for its matching millimeter range.
What’s Included
The SS to Millimeter Conversion Table lists every included size with its diameter range and approximate midpoint. Use it when a product listing gives only an SS number, or when your measured diameter needs to be matched with a likely stone size.
On the Millimeter Measuring Circles page, outlines increase from 1 to 12 mm in half-millimeter steps. Place an unmarked round stone over the closest circle, then compare that measurement with the conversion table.
The notes area provides space for the stone color, measured diameter, likely SS size, and seller.
Both actual-size chart pages include 2-inch and 50 mm calibration bars. The final page keeps the accuracy guidance, small-parts warning, personal-use license, and referenced sources together for future reference.
How to Use the Rhinestone Size Chart
Start by printing the PDF at 100% or Actual Size. Turn off Fit, Shrink, or other automatic scaling options, then measure both calibration bars with a reliable ruler.
If either bar is incorrect, adjust the printer settings and print again before comparing any stones.
For a labeled stone, find its SS number on pages 1 through 3 and review the corresponding diameter range.
For an unmarked stone, place it over the millimeter circles or measure straight across its widest point with calipers. Record the result in the notes area if you want to compare products or suppliers.
The printed circles work best as a quick visual estimate for round stones. For fitted settings, templates, expensive orders, or close size decisions, compare the seller’s specifications and use a physical sample or calipers before committing.
Ways to Use the Printable
Keep the chart near your jewelry-making supplies when sorting mixed rhinestones or planning repeated patterns.
It can also help you compare scale before placing stones on apparel, tumblers, cards, accessories, or other craft surfaces.
If you buy from more than one supplier, use the measurement notes to record how listed sizes compare with the stones you receive.
That small reference can make future ordering more consistent, especially when manufacturers use slightly different tolerances.
Important Accuracy and Safety Note
Rhinestone sizes can vary by brand, material, cut, coating, and manufacturing tolerance.
The printed SS circles use the midpoint of each listed range, so they are approximate visual references rather than exact product specifications.
Loose rhinestones may be a choking hazard. Keep them away from young children and pets, and follow the adhesive or hot-fix tool manufacturer’s instructions for ventilation, handling, and protective equipment.
