Flatback Post Length Size Guide
The right post length ensures comfort, proper healing, and a clean, flush look against your ear. Too short and the backing may press into the skin; too long and the post may snag or shift.
Our flatbacks are measured from the back of the disc to the tip of the post (not including the front piece).
Post Length Guide by Piercing Type
| Piercing Type | Recommended Length | Notes |
|---|---|---|
| Lobe (standard) | 5mm – 6mm | 5mm for very thin lobes; 6mm for most healed lobes |
| Lobe (thick / stretched) | 8mm | For thicker earlobes or stacked looks |
| Helix / Cartilage | 6mm – 8mm | Depends on ear thickness; 8mm recommended for fresh piercings |
| Tragus | 5mm – 6mm | 5mm for a snug healed fit; 6mm for more comfort |
| Conch | 8mm – 10mm | Thicker cartilage area; size up if unsure |
| Daith | 6mm – 8mm | Curved anatomy; consult your piercer |
| Rook | 8mm | Deeper fold requires longer post |
| Industrial | 10mm+ | Consult your piercer for exact sizing |
Tips for Getting the Right Fit
- 5mm — ideal for very thin lobes or snug healed piercings with minimal tissue.
- 6mm — the most versatile length; suits most healed standard piercings.
- 8mm — great for thicker ears, cartilage, or any healing piercing needing extra room.
- Fresh or healing piercings need extra room for swelling — go 1–2mm longer than usual.
- Not sure? 6mm is a safe starting point for most healed lobe piercings.
- Your piercer can measure your exact ear thickness with a calliper for the most accurate fit.

Looks very elegant and the 6 mm is the right size for my conch piercing. I love it!
The packaging was so thoughtful, and the earrings are absolutely gorgeous! I love this kind of dainty, delicate design—it goes with everything. I just wish there was a straight-post option too, haha.
Really happy with it! Looks so good, and the 6mm size is perfect for my helix.
This was the only brand has options of post length. They are reasonable but come with tool and cloth which other brand didn’t even include even they are more expensive. Also free delivery. So worth the money!
Bought it for replacement. Previously bought 6mm but they were too short for my ears.
Always come in cute box and cloth. It’s definitely worth the money.
Exactly as pictured and absolutely gorgeous! It was my first time putting in a flatback earring, and it went on so smoothly. I actually bought three styles, and I love that the little teardrop can be worn on either side. It's also the perfect size for my helix piercing.
So dainty and cute! It's super comfortable to wear, even while sleeping or showering.
Really happy with it! The size is perfect for my helix piercing. I do wish the post was a little thinner, but overall I love it.
It's so sparkly—it honestly looks just like my real diamonds.
