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.

Really nice! No fading so far, and they’ve been great to wear.
This is my third time buying from here, and I’ve never been disappointed!
The style is very wearable for everyday.

It’s small, delicate, and so pretty. Super comfortable too—no need to worry about it poking or digging in!

Just want to let you know im very happy with these earrings

It’s my first time seeing such thoughtful packaging! The earrings are absolutely beautiful too!
The bottom one is solid gold, and the 2mm one on top pairs really well with it. Very happy with how they look together.
great！
The color looks really nice and true to the photos. It goes perfectly with the new bracelet I bought, and the 5mm post is a great fit for thinner earlobes.
