Jewelry Guide | Earring Gauge Sizes Explained: 20G, 18G, 16G, 14G & How to Choose
When searching for the perfect pair of solid gold earrings, style and diamond sparkle aren't the only factors to consider—earring gauge size (thickness) plays a essential role in both comfort and ear health!
 

If you've ever felt confused by terms like "20G" or "18G," you're not alone. What does "G" stand for, and does a larger number mean a thicker or thinner post? In this Charis Grace Jewelry Guide, we break down everything you need to know.


1. What is "Gauge" (G)? The Larger the Number, the Thinner the Post!
In the world of jewelry and piercings, post thickness is measured using Gauge (abbreviated as G).
A quick rule of thumb to remember: "The higher the gauge number, the thinner the post; the lower the gauge number, the thicker the post."
Here is a handy comparison chart of common gauge sizes and their actual millimeter (mm) measurements:
| Gauge Size | Thickness (mm) | Common Uses & Piercing Placements |
|---|---|---|
| 20G | 0.8mm | Standard earlobe earrings, delicate posts (ideal for small or sensitive lobes) |
| 18G | 1.0mm | Flat Back earrings, cartilage piercings, everyday long-wear pieces |
| 16G | 1.2mm | Professional body piercings, helix, tragus, and cartilage piercings |
| 14G | 1.6mm | Thicker body piercings (navel, industrial, etc.) |
 

2. How to Choose the Right Gauge for You?
When choosing the right thickness, consider both piercing location and your daily wearing habits:
1. Standard Earlobe: Lightweight & Weightless Feel (Recommended: 0.8mm / 20G)
If you usually wear standard fashion jewelry or prefer a barely-there, ultra-comfortable feel, 0.8mm (20G) is the classic choice. It slides in effortlessly and offers effortless everyday wear.
2. 24/7 Wear & Cartilage Support: Stability & Comfort (Recommended: 1.0mm / 18G)
For sleeping, cartilage placements, or long-term wear, 1.0mm (18G) is the gold standard. A slightly sturdier post maintains the structure of your piercing, preventing holes from shrinking over time.

💡 Pro Tips from Our Jewelry Experts
* Never Force a Thicker Post: If you usually wear 20G (0.8mm) and want to transition to 18G (1.0mm), ensure your piercing is fully healed. Apply a drop of skin-safe oil for smooth insertion.
* Choose Hypoallergenic Solid Gold: Thickness matters, but material matters more! All Charis Grace pieces are crafted in solid 14K/18K gold, ensuring nickel-free, skin-friendly protection for everyday wear.
