GUIDE
Rhinestone size guide: SS6 to SS20
"SS" stands for stone size — an old jeweller's unit that has nothing to do with millimetres. This chart converts the most common hotfix sizes so you can set your Stoneplot canvas with confidence.
SS to millimetre chart
| SS size | Diameter | Best for |
|---|---|---|
| SS6 | ≈ 2.0 mm | Fine detail, small lettering, outlines |
| SS10 | ≈ 2.8 mm | The all-rounder — most designs, tees, logos |
| SS12 | ≈ 3.2 mm | Slightly bolder coverage, script fonts |
| SS16 | ≈ 4.0 mm | Big impact, reads well from a distance |
| SS20 | ≈ 5.0 mm | Statement pieces, stage costumes, large graphics |
How to choose
Smaller stones (SS6–SS10) hold fine detail but take longer to brush in and cost more per design. Larger stones (SS16–SS20) cover area fast and sparkle harder from a distance, but rounded shapes lose definition. When in doubt, start with SS10 — it is the industry standard for a reason.
Mixing sizes in one design
Stoneplot's random size mode lets you combine two or more stone sizes in a single map with an adjustable mix ratio — a technique often used in premium dance costumes to add texture and depth. The packing engine guarantees stones never overlap, so the mix stays production-safe.
Template hole sizing
If you are cutting a physical template, make holes roughly 0.2–0.4 mm wider than the stone so they drop in without forcing. Stoneplot works in true millimetres, so set the stone size, preview the spacing, and your SVG exports at exact scale — ready for your cutter.
