If you’ve ever browsed for body jewelry online or asked about sizing, you’ve probably seen the word gauge pop up a lot. And if it confused you, you’re definitely not alone. I get asked this question a lot, and it’s an important one.
This guide explains standard piercing gauges, what they mean, and which sizes are commonly used for different piercings.
📏 What Does Gauge Mean in Piercings?
Gauge refers to the thickness of the jewelry that goes through your piercing.
The system is a little backwards. The higher the number, the thinner the jewelry. So:
- 18g is thinner than 16g
- 14g is thicker than 16g
When I talk about “standard” gauges, I’m usually referring to the most commonly used size for initial piercings.
📝 Common Standard Gauges by Piercing Type
| Piercing | Standard Gauge |
|---|---|
| Earlobes | 22g or 20g (for mall studs), 18g or 16g (for professional piercings) |
| Helix / Cartilage | 16g+ |
| Nostril | 18g |
| Septum | 14g |
| Lip / Labret | 14g |
| Eyebrow | 16g |
| Tongue | 14g or 12g |
| Navel | 14g or 12g |
| Nipple | 14g or 12g |
| Genital Piercings | 12g, 10g, or even thicker, depending on anatomy and placement |
💡 Why Use Thicker Jewelry?
There are a few reasons I might choose a thicker gauge:
- Stability: Thicker jewelry tends to be more stable in high-movement areas (like nipples or navels).
- Anatomy: Some tissue types just do better with thicker jewelry.
- Aesthetics: Certain jewelry styles (like decorative ends or larger gems) work better on thicker posts.
- Long-term durability: Thicker jewelry tends to hold up better with time and wear.
I’ll always talk through gauge with you before I pierce and explain the why behind what I’m using.
📐 Can I Switch Gauges Later?
Absolutely. If the piercing is healed and the jewelry is changed properly. Downsizing to a thinner gauge is sometimes possible, but you should always consult your piercer before switching gauges.
Upsizing (stretching) is more complex and should only be done intentionally, slowly, and with professional guidance.
📸 Not Sure What Size You’re Wearing?
If you didn’t get pierced by me or aren’t sure what gauge you’re currently wearing, I offer jewelry check-ups and insertions. Bring your jewelry or let me size it for you. And if needed, I can custom order something in the correct size.

🛑 A Quick Note About At-Home Measuring
Please don’t try to measure your jewelry with a ruler or guess based on photos online. Gauge differences can be super subtle (we’re talking fractions of millimeters) and an incorrect size can lead to discomfort, rejection, or damage.
Final Thoughts
Choosing the right gauge for your piercing is part of setting you up for long-term success. I always select gauges based on your anatomy, lifestyle, and what’s going to heal best.
