Flat back gauge and length sizing guide for ear piercings

How to size a flat back stud

A flat back stud has a decorative top that threads onto a post ending in a smooth, flat disc. The disc rests against the back of the piercing so it sits flush, won't snag, and stays comfortable enough to sleep on. Two measurements make it fit right: gauge (post thickness) and length (post span).

Gauge — the thickness of the post

Gauge is how thick the post is, and it should match what your piercer used so the stud seats securely without shifting. The scale runs in reverse — a smaller number is a thicker post, so an 18G post is thinner than a 16G. Most flat back ear and nostril piercings use 18G or 16G.

Length — the post that spans your piercing

Length is the distance from the flat disc to the front of the stud — the part that passes through your piercing, measured without the decorative top. While healing, a little extra room (often 8mm) leaves space for swelling; once healed, a shorter post (6mm or 5mm) keeps the top sitting close and flush. Too long and the top spins or catches; too short and the disc presses in.

Not sure? Match the gauge and length on jewelry that already fits you, or check with your piercer.

Stunning 🤩

Exactly what I was looking for and more for my new nose ring. Only thing is I wish I understood how to better gauge the length of the bar. The one I purchased came as ordered but the bar was too short for my nostril simply because I didn’t know what size to order. Instead, I got a stud from my piercer. Though it may have inspired me to pierce my cartilage instead as it’s too cute and gorgeous not to wear.

Can you customize the yin/yang piece to fit curved 16g 14kt gold barbell for a lateral lip piercing? Purchased two not realizing the screw in post is too long for curved barbell. May need to re-order.

FreshTrends.com

Hello,

Thank you so much for your message!

We may be able to customize the yin/yang piece to fit a **curved 16g 14kt gold barbell** for your lateral lip piercing, depending on the exact design and compatibility with the attachment style.

Since you mentioned the current screw-in post is too long for your curved barbell, it’s very possible we may need to **adjust the post length or recommend a different backing configuration**, or in some cases, re-make the piece to ensure a proper fit and secure wear.

We would recommend reaching out to our customer service team so we can review your exact setup and confirm the best option for you. From there, we can determine whether a **custom modification or re-order would be the best solution** and provide pricing and timelines.

We’d be happy to help you get a setup that works comfortably and securely for your piercing.

Warm regards,

FreshTrends Customer Care

Hi, I will like to buy this for a nose stud in yellow gold, 16 guage, 6.5mm length, the sides in the picture looks like the yellow gold stud has a white gold casting on the side. Is it possibe to have it in just yellow gold. Many thanks

The yin yang is not two-tone; it is only one gold color.
