How to Choose the Right Rhinestone Size

Match the 30ss Rhinestone to a Pencil Eraser

Use one familiar real-world object to turn the proportional chart above into an approximate actual-size reference.

A 30ss rhinestone measures approximately 6.3mm, about the diameter of a standard pencil eraser. On a desktop computer, hold down the Ctrl key while scrolling your mouse wheel until the 30ss rhinestone above matches the diameter of your pencil eraser. Because every rhinestone above is displayed in the correct proportion to 30ss, the other stones will then provide an approximate actual-size reference on your screen.

Small Crystals for Maximum Detail

Tiny stones and shapes create intricate detail for designs intended to be viewed up close.

Tiny Round Rhinestones: 3ss, 5ss, 7ss and 9ss are tiny non-hotfix sizes, while 6ss, 8ss and 10ss are tiny hotfix sizes.

Small Flatback Shapes: MAXIMA and Priceless Crystal offer miniature crystal shapes measured in millimeters. They are useful for nail art, intricate designs and small craft projects where shape adds texture and detail.

Nail Art Mixes & Preciosa Crystal Faerie: Nail art mixes combine small stones and shapes, while Crystal Faerie micro crystals can be poured over thick nail glue or gel to create an encrusted pavé effect.

For nail professionals, smaller crystal packages can also work well as a salon point-of-sale or manicure add-on because the quantity and project cost remain accessible for an individual manicure.

Bigger Stones for Visibility and Drama

Larger rhinestones create stronger flashes of crystal and make embellishment easier to see from a distance.

Costuming & Apparel: 12ss, 16ss and 20ss provide versatile options for garment embellishment, with both hotfix and non-hotfix choices available.

Stage Sparkle & Bold Accents: 20ss, 30ss, 34ss, 40ss and larger stones create stronger visual impact from a distance. Some 30ss and 34ss stones are available in both hotfix and non-hotfix, while 40ss and larger round stones are generally non-hotfix.

Starcut Crystal Sew-On Jewels: Large sew-on stones are measured in millimeters rather than SS. They can be sewn into a design or glued when appropriate and are useful when you want an oversized focal point.

Stone Size Changes More Than the Look

The size you choose changes how many stones you need, how quickly you can cover an area and how long the design may take to apply.

Smaller Rhinestones: Create finer detail and more intricate patterns, but more stones are needed to cover the same area or line. Applying many tiny stones can also require more placement time.

Larger Rhinestones: Cover space more quickly and create stronger individual flashes of crystal. Fewer stones are generally required to cover the same area, which can also reduce application time.

5ss + 9ss + 16ss or Tiny Shapes

Several tiny sizes together can turn a small surface into a detailed crystal design.

Crystals for Nails mix packs make it easy to combine several sizes in one manicure or small-scale design. Mixes may include 5ss, 9ss and 16ss round rhinestones or substitute a tiny crystal shape to add another layer of texture and interest.

6ss + 10ss Hotfix

Tiny hotfix stones make it possible to follow finer lines, curves and details in a transfer design.

Small 6ss and 10ss hotfix rhinestones work well together when a transfer includes fine lines, curves or detailed areas. Mixing the two sizes lets you build detail while varying the visual weight of different parts of the design.

Build a Multi-Size Mix in Your Favorite Color

Start with the color you love, then combine several sizes to create depth, movement and a more dimensional surface.

For costumes and performance apparel, try shopping by color first. Choose your color and then select several available sizes to build a coordinated multi-size design.

You can stay within one rhinestone color for a polished tonal effect or combine complementary and closely related colors using our Virtual Rhinestone Color Chart.

A multi-size scatter or scatter fill is one of the easiest ways to use several sizes together. Randomly vary both stone size and placement to create dimension and interest without needing a ruler or perfectly repeated spacing.

What does SS mean in rhinestone sizes?

SS means Stone Size. It is a traditional sizing system used for round rhinestones. As the SS number increases, the diameter of the rhinestone increases.

What are the most popular rhinestone sizes?

For costuming and apparel, 16ss and 20ss are our most popular sizes. They sit in a versatile middle range and can be used as larger accents in fine-detail designs or as smaller supporting stones in designs built around larger rhinestones.

What rhinestone size is best for dance costumes?

Many dance costume designs use 16ss and 20ss as versatile foundation sizes and add larger stones such as 30ss, 34ss or sew-on jewels for greater stage visibility. The best combination depends on viewing distance, design detail and the amount of sparkle you want.

What rhinestone sizes are best for nail art?

Very small stones such as 3ss, 5ss, 7ss and 9ss non-hotfix rhinestones are useful for detailed nail designs. Small crystal shapes, Nail Art Mix Packs and Preciosa Crystal Faerie provide additional options for texture and micro-detail.

What rhinestone sizes are available in hotfix?

Tiny hotfix sizes include 6ss, 8ss and 10ss. Sizes from approximately 12ss through 20ss are available in both hotfix and non-hotfix options. Some 30ss and 34ss stones are also available in both applications, while 40ss and larger round stones are generally non-hotfix.

Should I mix different rhinestone sizes?

You can. Mixing sizes creates dimension and visual movement. Multi-size scatter designs are especially forgiving because the stones can be placed randomly rather than in perfectly repeated spacing.

Are hotfix and non-hotfix rhinestones the same physical size?

The same nominal SS size is generally comparable in diameter whether the rhinestone is hotfix or non-hotfix. The difference is the backing and application method. However, the available size ranges are not identical.

Is the same SS exactly the same size across every rhinestone brand?

Not necessarily. SS represents a size range, so there can be small differences in diameter between brands and cuts. Check the manufacturer’s measurements when exact sizing is important.

Can I see the actual rhinestone size on my computer screen?

Screen sizes and zoom settings vary, so an online image cannot automatically display at true physical size. On a desktop computer, you can use the 30ss pencil-eraser reference above to adjust your browser zoom and create an approximate actual-size comparison.

How do I convert SS rhinestone sizes to millimeters?

What if I want something much larger than a standard round rhinestone?

Consider a sew-on crystal jewel. Large sew-on stones are measured in millimeters and can create dramatic focal points on costumes, apparel and accessories. Depending on the project, they may be sewn into place or glued when appropriate.
