Flatback Post Length Size Guide
How to Choose Your Post Length
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.

It's so so pretty in person. The stud itself isn't centered so that you can adjust it based on wherever you want to wear it and I really appreciate that. Will purchase more in the future!
The design isn't flashy but has a lot of detail. The color is very versatile, perfect for daily commutes or shopping trips. The craftsmanship is also quite delicate.
Bought this for my flat piercing. The chain is a tiny bit short, but it still fits just right — looks really good, very minimalist.
Love it, super sparkly and bright. Will definitely repurchase. The store's service is great, and the craftsmanship and details are excellent.
The actual product has great quality — really like it. Leaving a positive review.
A gift for my elder. She loves it — never needs to take it off. Makes her look younger and so chic.
It's insanely gorgeous. I only wish I had more ear piercings. But I've already bought way more than my ears can handle.
This earring design is pretty minimalist — really easy on the eyes. The color is super eye-catching, and the stones are so sparkly they almost blind you. This time I played it smart and used an insertion taper to help with positioning, so I could just poke it straight through easily from the back.
