A helix piercing is most commonly pierced at 16G (1.2 mm). Some studios use 18G (1.0 mm) for smaller jewellery, while 14G (1.6 mm) is less common and usually chosen for thicker cartilage, larger hoops, or specific jewellery styles. If you are buying jewellery without knowing your size, 16G is the safest default for most helix piercings.

What is the standard gauge for a helix piercing?

The standard gauge for a helix piercing is 16G (1.2 mm) in most professional piercing studios. This size provides a good balance between stability, comfort, and jewellery availability. A 16G piercing is less likely to cut into cartilage than a thinner 20G earring post and is easier to heal than a very thick 14G piercing. As of 2026, implant-grade titanium flat-back labrets in 16G remain the most common initial jewellery choice for helix piercings. When you see jewellery listed as “1.2 mm,” that is the same size as 16G. Many online shops display both measurements, so checking for either 16G or 1.2 mm helps avoid ordering the wrong size.

Is a helix piercing 16G or 18G?

Both exist, but 16G is more common. An 18G helix piercing measures 1.0 mm and is sometimes used for delicate studs or very small ears. The downside is that thinner jewellery can migrate more easily and may create a less stable channel in cartilage. A 16G piercing is usually preferred for everyday wear because it offers better support for hoops, huggies, and flat-back studs. If your piercer started you at 18G, do not force 16G jewellery into the piercing without professional guidance; stretching cartilage should be done gradually if needed.

How do I know my helix piercing gauge?

The easiest way is to ask the piercer who performed the piercing, but you can also check the jewellery packaging or measure the post. Common helix sizes are:

• 18G = 1.0 mm

• 16G = 1.2 mm

• 14G = 1.6 mm

A jewellery caliper provides the most accurate measurement. If the piercing is healed and the jewellery slides in loosely, it may be thinner than you expect. Never guess by visual appearance alone because the difference between 18G and 16G is only 0.2 mm, which is difficult to see with the naked eye.

Can I wear a regular earring in a helix piercing?

Usually not. Most regular fashion earrings are 20G-22G (0.8-0.6 mm), which are thinner than a typical helix piercing. Wearing a much thinner post in a healed 16G helix can cause the hole to shrink gradually. In a healing helix, switching to a thinner earring can also increase movement and irritation. Cartilage piercings heal more slowly than lobe piercings, so stable jewellery is especially important during the first several months. If you want a delicate look, choose jewellery specifically made in 16G rather than using a standard lobe earring.

What length should helix jewellery be with a 16G piercing?

Gauge refers to thickness, while post length is a separate measurement. Initial helix jewellery is often 6-8 mm long to allow room for swelling. After swelling settles, many people downsize to 5-7 mm for a snugger fit. A post that is too long can catch on hair and increase irritation, while a post that is too short can press into the cartilage. Your piercer should assess swelling before downsizing. Hoops are measured by inner diameter rather than post length; common healed helix hoop sizes are 6 mm, 8 mm, and 10 mm.

What metal is best for a helix piercing?

For a new helix piercing, the safest choices are implant-grade titanium, solid 14k or 18k gold, or high-quality 925 sterling silver that is nickel-safe and worn after healing unless specifically approved by your piercer. Smooth, well-finished jewellery reduces friction and helps prevent irritation bumps. Quirksmith offers handcrafted 925 sterling silver helix jewellery intended for everyday wear once the piercing has healed. Avoid mystery-metal fashion jewellery, plated brass, or nickel-containing alloys, especially during the healing period.

FAQ

Is 16G bigger than 18G?

Yes. 16G (1.2 mm) is thicker than 18G (1.0 mm).

Can a 16G helix shrink to 18G?

Yes. If you wear 18G jewellery for an extended period, a healed 16G piercing may gradually shrink.

Is 14G too big for a helix piercing?

Not necessarily, but it is thicker than the standard size and is usually chosen intentionally by a piercer.

What gauge are most helix hoops?

Most helix hoops are sold in 16G (1.2 mm), with 18G also widely available.

Can I change my helix jewellery myself?

Wait until the piercing is fully healed, which is often 3-9 months, and confirm the gauge before changing jewellery.
