Understanding Rhinestone Size Codes (SS, mm)
When working with rhinestones, understanding their sizing system is crucial for achieving the desired look in your projects. Unlike other craft materials measured in inches or centimetres, rhinestones primarily use two systems: the 'SS' system (Stone Size) and millimetres (mm).
SS (Stone Size): This is the most common sizing system used specifically for rhinestones. It's an arbitrary number, not directly related to any particular unit of measurement. Higher SS numbers indicate larger rhinestones. For example, SS6 is smaller than SS10.
Millimetres (mm): This is a standard metric unit of length. Rhinestone sizes can also be expressed in millimetres, representing the diameter of the stone. This provides a more direct and intuitive understanding of the rhinestone's size.
It's important to note that the relationship between SS numbers and millimetres isn't always exact due to slight variations in manufacturing. However, standard conversion charts provide a reliable approximation.
Converting Between Size Systems
While the SS system is widely used, understanding the millimetre equivalent is often helpful, especially when comparing rhinestones to other materials or when working with patterns that specify measurements in metric units. Here's a general conversion guide. Keep in mind that these are approximate values:
| SS Size | Approximate Diameter (mm) |
| :------ | :------------------------- |
| SS4 | 1.5 - 1.7 mm |
| SS6 | 1.9 - 2.1 mm |
| SS8 | 2.3 - 2.5 mm |
| SS10 | 2.7 - 2.9 mm |
| SS12 | 3.0 - 3.2 mm |
| SS16 | 3.8 - 4.0 mm |
| SS20 | 4.6 - 4.8 mm |
| SS30 | 6.3 - 6.5 mm |
| SS34 | 7.0 - 7.2 mm |
| SS40 | 8.2 - 8.4 mm |
| SS48 | 10.0 - 10.4 mm |
This table provides a quick reference for converting between SS sizes and millimetres. You can also find more detailed conversion charts online or use a rhinestone size conversion tool. Remember to always double-check the specific measurements provided by the rhinestone supplier, as slight variations can occur.
Visual Guide to Rhinestone Sizes
A visual guide is invaluable when choosing the right rhinestone size. Looking at a chart or image that displays rhinestones of different SS sizes side-by-side allows you to quickly grasp the relative scale and determine which size best suits your project. Many online retailers and crafting websites offer such visual guides. Consider printing one out for easy reference in your workspace.
When using a visual guide, be aware that the perceived size of a rhinestone can also be influenced by its colour and cut. Darker colours tend to appear smaller, while brighter colours and more complex cuts can make a rhinestone seem larger. Always consider these factors when making your final decision.

Choosing the Right Size for Your Project
Selecting the appropriate rhinestone size is crucial for achieving the desired aesthetic and functionality in your project. Here are some factors to consider:
Project Type: The type of project will heavily influence the ideal rhinestone size. For delicate embellishments on clothing or intricate nail art, smaller sizes like SS4 to SS10 are generally preferred. For larger projects like decorating phone cases, shoes, or creating statement jewellery, larger sizes like SS16 to SS30 might be more suitable.
Desired Effect: Consider the overall look you want to achieve. Smaller rhinestones create a subtle, shimmering effect, while larger rhinestones offer a bolder, more eye-catching statement.
Fabric/Material: The type of fabric or material you're applying the rhinestones to also matters. Delicate fabrics might not be able to support the weight of larger rhinestones. Porous materials might require larger rhinestones for better adhesion.
Application Method: The application method (e.g., hotfix, glue-on) can also influence the size choice. Hotfix rhinestones might be slightly larger to accommodate the adhesive backing.
Complexity of Design: Intricate designs with fine details will generally require smaller rhinestones to maintain clarity and precision. Simpler designs can often accommodate larger rhinestones for added impact.
Here are some examples of rhinestone sizes commonly used for different applications:
Nail Art: SS3 - SS7
Clothing Embellishments (delicate fabrics): SS6 - SS12
Clothing Embellishments (sturdier fabrics): SS12 - SS20
Phone Cases: SS16 - SS30
Shoes: SS20 - SS34
Jewellery Making (pendants, earrings): SS8 - SS40 (depending on the design)
Dance Costumes: SS16 - SS30
Remember to experiment and test different sizes to find the perfect fit for your specific project. Don't hesitate to order a small sample of various sizes to see how they look and feel before committing to a larger purchase.
Tools for Measuring Rhinestones
While most rhinestones are labelled with their SS size or millimetre measurement, there might be situations where you need to measure them yourself. This could be because the rhinestones are unlabelled, or you want to verify the accuracy of the size.
Here are some tools that can be used for measuring rhinestones:
Digital Caliper: This is the most accurate tool for measuring rhinestones. A digital caliper provides a precise measurement in millimetres, allowing you to determine the exact size of the stone. Digital calipers are relatively inexpensive and easy to use.
Ruler with Millimetre Markings: A standard ruler with millimetre markings can be used to get an approximate measurement of a rhinestone. However, this method is less accurate than using a digital caliper.
Rhinestone Size Chart: Many rhinestone suppliers provide printable size charts that you can use to compare the size of your rhinestones to the images on the chart. This is a quick and easy way to estimate the size, but it's not as precise as using a measuring tool.
Magnifying Glass: A magnifying glass can be helpful when measuring rhinestones, especially smaller sizes. It allows you to see the stone more clearly and get a more accurate measurement.
When measuring rhinestones, it's important to measure the diameter of the stone at its widest point. Also, be aware that there might be slight variations in size between different batches of rhinestones, even from the same supplier. If precise sizing is critical for your project, it's always a good idea to measure a sample of rhinestones before starting.
Understanding rhinestone sizes and measurements is essential for any crafter or designer working with these sparkling embellishments. By mastering the SS and millimetre systems, using visual guides, and selecting the right size for your project, you can create stunning and professional-looking results.
