Eyelet Tunnel Gauge

00 gauge explained: sizes, shrinkage, and safe stretching to get there

If you have been living at 2g or 0g and eyeing 00g, you have probably heard two things: the millimeters are confusing, and 0g to 00g can feel like a wall. Both are true. The fix is simple, though. Know your numbers, respect your timeline, and use tools that make small, controlled moves.

This guide breaks down 0g vs 00g, real millimeter conversions, what people mean by “point of no return,” and how to bridge the last jump without wrecking your lobes. No gatekeeping, no scare tactics, just practical steps and gear that actually helps.

Gauge sizes in millimeters (quick chart)

Gauge numbers count down as jewelry gets bigger, then switch to inches/mm once you pass 00g. Here are the sizes you will care about on the way to 00g:

  • 2g = 6 mm

  • 1g = 7 mm (less common but useful as a half step)

  • 0g = 8 mm

  • 00g = 9 to 10 mm (often labeled 9.0 or 10.0 mm)

  • 7/16 inch = 11 mm (the next size after 00g)

  • 1/2 inch = 12.7 mm

Key takeaways:

  • 00g is not a single size everywhere. Many brands cut it at 9.0 mm, some at 10.0 mm. Read the product listing.

  • 0g is smaller than 00g. If someone says 0g is “bigger,” they are mixing up the numbering.

0g vs 00g: why the jump feels big

0g to 00g adds 1 to 2 mm of diameter depending on the manufacturer. On paper that sounds small. In your body, it is a real stretch. Tissue gets tighter as it grows, and the lobe does not distribute that final increase evenly without time and technique.

How to make it manageable:

  • Plan for a half step. If your 00g target is 10 mm, consider 9 mm first. If you are at 0g (8 mm), sliding to 9 mm, then resting, then going to 10 mm is far kinder to your ears.

  • Stretch with gradual tools, not brute force. A smooth taper or pincher that lets you pause mid-size is your friend.

Our go-to tools for the last sizes

For controlled upsizing, we recommend the KBJ Stainless Steel Pinchers Stretching Kit. The curve and taper let you ease through fractionally larger diameters, hold, then nudge forward when your tissue is ready. Steel is also easy to sanitize and glides well with a tiny amount of water-based lube.

Once you are fully healed at your goal size, KAOS silicone options shine for comfort. Their silicone eyelets and plugs feel feather-light and low profile for everyday wear. Stick to steel or glass for the stretch itself, then swap to silicone once your lobes are calm and settled.

Safe timelines and what “point of no return” really means

Here is the truth. “Point of no return” is not a single universal size. It depends on genetics, age, stretch method, time between jumps, and how long you have stayed at a larger size. That said, many people find that past 2g to 0g, complete shrink-back to an unpierced look becomes less likely. At 00g, some lobes will shrink significantly, some will hold a small hole, and some will need help from a professional piercer or a surgeon to fully close.

General pacing that respects your tissue:

  • Wait at least 6 to 8 weeks between size increases once you are at 2g and larger. Longer is better, especially 0g to 00g.

  • If the jewelry feels tight, stings, or looks shiny or glossy, stop. That is micro-tearing waiting to happen.

  • If you do get a small tear or inflammation, downsize one step and switch to gentle aftercare until the skin normalizes.

For aftercare, stick with sterile saline and keep it simple. You can find sterile saline for piercings and related piercing aftercare supplies in one spot if you need to restock.

Wearable area: 3/8 inch vs 1/2 inch

“Wearable area” is the space on the post that sits inside your piercing. Too short and your lobe gets pinched; too long and you have awkward protrusion.

  • 3/8 inch wearable area typically suits normal-width lobes.

  • 1/2 inch wearable area is better if you have thicker lobes or any swelling during the stretch.

Many steel single flare or double flare tunnels list the wearable area. When in doubt, measure the thickness of your lobe at rest. If you are in the middle, 1/2 inch usually gives you wiggle room during the stretch and early heal.

Common mistakes to avoid

  • Rushing sizes. If you need to push, it is not ready.

  • Forcing with acrylic tapers. Acrylic scratches easily and can harbor bacteria. Use steel for the stretch.

  • Oiling too soon. Heavy oils and balms can trap debris and over-soften fresh tissue. For new stretches, keep it to sterile saline, a light water-based lubricant for insertion, and hands-off otherwise. Oils are fine once you are healed.

  • Sleeping in double flares during the stretch. They can pinch. Single flare or flat-back styles are safer until you are settled.

FAQ: quick answers to the big 00g questions

  • What size ear gauge is 00? Most commonly 9 to 10 mm. Check the exact millimeter listed by the brand.

  • Is 00g the point of no return? Not automatically. Many people at 00g see significant shrinkage, but full closure is not guaranteed and varies by body and history.

  • Is 00 or 0 gauge bigger? 00g is bigger. 0g is 8 mm, while 00g is 9 to 10 mm.

  • Is 0g to 00g a big jump? Yes. It can be a 1 to 2 mm leap. Use half steps like 9 mm and take extra healing time.

  • Can 00 gauges go back to normal? Sometimes. Your ears may shrink a lot, but a completely unpierced look is not guaranteed. Results vary and can depend on how long you wore 00g.

  • Will your ears shrink back after 00g? Often they shrink down, but the final size is individual. If you plan to return to tiny jewelry or none at all, be conservative with your timeline and consider holding at 0g.

  • Is 00 the same as 10 mm? Sometimes. Some brands label 00g as 10 mm; others use 9 mm. Read the listing.

  • What are the risks of using 00 gauges? Main risks are micro-tears, blowouts, irritation, and scarring, especially if you rush, skip half steps, or use poor materials. Go slow, use steel tools, and keep aftercare simple.

A smarter path to 00g

If you want 00g without drama, treat it like a slow project:

  • Move from 0g (8 mm) to 9 mm using a smooth steel pincher or taper, then rest.

  • Assess fit, circulation, and comfort for several weeks. No stinging. No constant pressure.

  • Step to 10 mm only when your lobe says yes. If it says no, listen.

Once healed, swap into something comfortable for daily wear. KAOS silicone eyelets are a favorite for soft edges and barely-there feel. And if you want sleek, durable basics at any stop along the way, 316L stainless steel pieces are hard to beat.

The short version

  • 00g is 9 to 10 mm and is larger than 0g.

  • 0g to 00g feels big because it is. Use a 9 mm half step and take your time.

  • “Point of no return” varies. Some ears at 00g shrink a lot, some less. No blanket promises.

  • Choose the right wearable area: 3/8 inch for most lobes, 1/2 inch for thicker lobes or early stretches.

  • Use steel for stretching, keep aftercare simple, and avoid rushing.
