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.

Love this earring! Sparkly! Got the smallest size for the top part of my ear … i wanted it to be tiny w/o hanging space and it fits perfecty….Great packaging and fast shipping too
小巧精緻的款式。我不太喜歡一般耳針，因為躺著會硌耳朵，這種平底底座的設計就完全不會。希望它可以成為我的長期主義單品，天天戴都不膩，哈哈哈！
Perfect for everyday wear. It's subtle, elegant, and adds just the right touch without being too flashy.
The color goes with everything, looks great no matter how you style it!
So pretty and really well made! It's just a tiny bit tricky to put on, but I guess I'm just not used to this style of flatback earrings yet.

I just fall in love with these 4-Prong Moissanite Flatback Earring. Sparkingly cute and beautiful match with everyday look. I would never take them out and let's see they will be sparkling until then.
I absolutely love these earrings—they're so pretty! The design is simple, versatile, and beautifully delicate. They're small enough for everyday wear but still stand out in the best way. The insertion pin that comes with them is super helpful and makes putting them on so much easier. They're comfortable, easy to wear, and go with everything. So far I'm really happy with them—next test is seeing how they hold up during hair-washing!
