Determining the correct gauge for your jewelry, particularly for piercings, is essential for comfort, fit, and proper healing. The easiest way to identify your gauge size is to measure any jewelry you are currently wearing and compare it to a standard gauge chart.
Understanding Gauge Sizes
It's important to know that gauge sizes work in reverse: a higher number indicates a thinner piece of jewelry, while a smaller number signifies a thicker one. For example, an 18 gauge (18G) post is thinner than a 16 gauge (16G) post. This system is common for body jewelry and wire.
How to Determine Your Gauge Size
There are a few reliable methods to find out what gauge you need:
1. Measure Existing Jewelry
If you already have a piece of jewelry that fits well, this is the most straightforward approach. You will need to measure the thickness of the post or wearable area of the jewelry.
- Use Digital Calipers: For the most accurate measurement, use digital calipers. These tools provide precise readings in millimeters.
- Carefully measure the diameter of the jewelry's post.
- Once you have the measurement in millimeters (mm), refer to the gauge chart below to find the corresponding gauge size.
- Compare to a Gauge Card: Many piercing studios or online retailers offer physical gauge cards or wheels. You can slide your jewelry into the slots to find the matching gauge.
2. Consult a Professional Piercer
If you are unsure or are getting a new piercing, the safest and most accurate method is to visit a professional piercer. They can:
- Measure your piercing directly: Using specialized tools, they can precisely determine the gauge of your piercing.
- Recommend the appropriate gauge: For new piercings, they will select a gauge that promotes optimal healing.
- Offer advice on jewelry materials and styles: Ensuring you choose jewelry that is safe and suitable for your body.
3. Review Your Piercing Records
If you had your piercing done professionally, the piercer might have provided you with aftercare instructions that include the initial gauge size. Check any documentation you received.
Standard Gauge Conversion Chart
Once you have measured your jewelry in millimeters, use the following chart to identify your gauge size. This chart provides common gauge sizes and their approximate millimeter equivalents for body jewelry.
| Gauge (G) | Millimeters (mm) | Description (Relative Thickness) |
|---|---|---|
| 20G | 0.8 mm | Very Thin (e.g., standard earlobe earrings) |
| 18G | 1.0 mm | Thin (e.g., common for nostril, earlobe) |
| 16G | 1.2 mm | Standard (e.g., helix, tragus, navel, lip) |
| 14G | 1.6 mm | Common (e.g., industrial, nipple, tongue) |
| 12G | 2.0 mm | Thicker (e.g., stretched earlobes, larger body piercings) |
| 10G | 2.5 mm | Thicker still (e.g., stretched earlobes) |
| 8G | 3.2 mm | Much Thicker (e.g., stretched earlobes) |
| 6G | 4.0 mm | |
| 4G | 5.0 mm | |
| 2G | 6.0 mm | |
| 0G | 8.0 mm | |
| 00G | 10.0 mm | Very Thick (common starting point for larger stretches) |
Note: Millimeter conversions can vary slightly between manufacturers. This chart provides general guidelines.
Important Considerations When Choosing a Gauge
- Initial Piercing Gauge: Piercers often use a slightly thicker gauge for initial piercings to promote better healing and reduce the risk of migration. It's crucial not to downsize the gauge too early.
- Piercing Location: Different body parts typically accommodate different standard gauges. For instance, earlobes are often pierced at 20G or 18G, while navels are commonly 14G.
- Stretching: If you plan to stretch a piercing, it's a gradual process that involves slowly increasing the gauge size over time. Always consult with a professional piercer for safe stretching practices. Learn more about safe body piercing practices from the Association of Professional Piercers (APP).
- Jewelry Type: Ensure the jewelry you select is made from body-safe materials like implant-grade stainless steel, titanium, or solid gold to prevent irritation or allergic reactions. Research safe jewelry materials before making a purchase.
By understanding how gauges work and utilizing accurate measurement techniques, you can confidently choose the correct jewelry for your piercings. When in doubt, always seek the expertise of a professional piercer.
