Piercing Area & Terminology
    The forward helix is a beautiful piercing location, making the most of the small piece of skin located just above the tragus.
  • ROOK
    A rook piercing is located just below the flat part of the ear, in the ridge of cartilage that hangs below. This is an impressive and unique piercing to have!
    Daith piercings are one of our personal favourites at Beatti due to the beautiful front-facing clickers that can be worn, making a big statement to any ear look.
    A tragus is one of the most common piercing placements as the jewellery in this location can be easily shown off with a beautiful statement labret or a dainty hoop.
    One of the most popular ‘starter’ piercings after lobes, a helix is located at the top of the ear in the cartilage and provides lots of possibilities for the different jewellery styles you can wear.
  • FLAT
    A flat piercing is located on the flat part of the ear, it allows space to experiment with statement labrets including those with hanging dangles for an eye-catching ear look.
    A conch piercing is a popular option for those wanting to wear a hoop that orbits around the center of their ear, or for nestling a touch of subtle sparkle inside with a labret.
  • LOBE
    The one that gets us all hooked! A lobe piercing is the most common type of ear piercing, located in the fleshy part of the ear lobe and not typically too painful.

*In general, if your ear was pierced with a gun, you will typically have the option of 18-20 gauge jewelry. If your piercing was done with a needle, jewelry in the range of 16-20 gauge will usually be suitable. However, please keep in mind that without a personal evaluation, we cannot provide precise recommendations, as individual variations exist. These are common standards that apply to most individuals.

*Please note that it is difficult to provide precise determinations without an in-person evaluation, as everyone's ear shape is unique. We strongly recommend visiting your local piercer for an accurate measurement and to determine your exact size. They will be able to assess your individual needs and provide personalized recommendations for your speci c piercing.

Earring Parts & Terminology

When it comes to piercing jewelry, the three main specifications to consider are the gauge thickness, length, and diameter. These specifications play a crucial role in finding the right fit for your piercing.

Huggie & Hoops

Stud Earrings

Type of stud Earring Backings
Labret Back

The flat labret back offers enhanced comfort, reducing pressure and irritation. It promotes safety by minimizing snagging and is easy to clean. Enjoy comfort and style effortlessly.


The barbell is a standard and traditional piercing backing, known for its ease of wear and removal. While it may be less ideal for sleeping, it still offers comfort and versatility for everyday use.


The butterfly earring is a well-known classic. It is a standard stud or post earring that many people wear. Embrace the timeless beauty and simplicity of this popular choice for everyday elegance.

What is Flat Back Studs??

Flatback earrings are a type of earring that features a flat disc or plate at the back, which rests against the skin, providing stability and comfort. Flatback earrings come in various styles using screw-on backing, including internally threaded and externally threaded, and threadless ends, also known as push pin labret. They are a popular choice for everyday wear because they are comfortable and less likely to get caught on clothing or hair compared to earrings with traditional butterfly backing. Flatback earrings are also often used for multiple ear piercings, like cartilage or tragus piercings, as their flat posts can prevent irritation and allow for easier healing.

Why Different Post Length and Thickness??

Every ear possesses a distinct profile. The ideal length of the flatback post for your ear depends on the specific characteristics of your ear, such as its thickness, placement, and the position of your piercing.
It is important to choose the right post for your ear structure.

We offer a
5mm, 6mm, 8mm and 10mm post in lengths
16G, 18G and 20G in thickness
so you can choose the best fit for your own ear.

All of our flatback posts come with corresponding color variation with your jewelry including, rhodium silver, 14k gold, 14k rose gold.

Post Length and Gauge (Thickness)

The length (mm) refers to the measurement of the earring post itself, specifically the portion that goes through the earhole, excluding the threaded part.

Gauge (Thickness)

The gauge represents the thickness of the jewelry that passes through the piercing hole. It is also the size of the needle used for creating a fresh piercing.

16G — Commonly used for cartilage piercings.
(Eyebrow, Monroe, Tragus, Helix, Rook, Conch, Daith, Lip, Septum)

18G — Can be used for both lobe and cartilage piercings.
(Nose, Ear, Cartilage, Forward Helix)

20G­ — You’ll find on traditional butterfly back earrings.
(Nose, Ear)

Type of Threads

Threadless labret piercing is an alternative to traditional piercing methods. It features a flat back design, eliminating the need for screws. Instead, it utilizes a push-pin mechanism for easy insertion. With its comfortable and secure fit, the threadless labret provides a comfortable wearing experience.

Internally Threaded

Internally threaded labret jewelry has an inside-threaded post and a flat back, ensuring comfort for daily wear and sleep. It allows easy decorative end changes without removing the post, reducing irritation. This jewelry is safer to insert than external threading, but securing the end needs precision. Recommended for new piercings due to comfort and reduced irritation risk.

Externally Threaded

The externally threaded labret has a flat back and threads on the outside of the post. It's sleep-friendly due to its flat back but can be tricky to insert as it requires aligning the post with the piercing hole from behind the ear. Consulting a piercer for assistance is advised.

Why is the Threadless Top Pre-Bent?

The pre-bent pin creates tension to secure the jewel head into place inside the post and to hold the jewelry together.
Here is the half section view of a threadless labret where you can see how the bent top sits inside of the post:

How to Use Threadless Labret

Insert the pin about 1/3 into the bar. The pin is pre-bent slightly to assist in secure placement.

Gently bend the pin by hand as demonstrated. The pin's tension ensures a secure attachment to the bar. Adjust the bend to achieve the desired level of tightness, as the more you bend, the tighter the fit becomes.

Push the pin fully into the bar post to secure the closure. The tension from the pin's bend keeps the top securely in place.

To remove, pull ends apart. If closure is tight, twist jewel head while pushing it away from the bar post. Simple and comfortable removal.

It is possible to take this process while wearing a threadless labret. However, we recommend pre-bending the pin beforehand, so that it is easy to bend the pin to create the right amount of tension without being too loose or too tight.

How to Wear Threadless Labret

Insert the bar post through the BACK of your piercing.

Once the bar post is peeking through the front of your piercing, carefully take the jewel head and insert the pre-bent pin into the bar post.

Firmly push both ends together with your finger, then gently tug both ends to make sure it’s secure.

Use 2 fingers (pointer & thumb) to apply equal pressure when pushing the pin fully into the bar post (Process #3). That way the pin goes straight into the post without bending over.

How to Wear Threaded Labret

1. Take the same process as 1. "How to wear threadless labret".
2.  Thread the jewel head into the post by rotating it (while holding the back piece) to tighten and secure your jewelry.

How to fix/correct the pin attached to the jewel head

The pin attached to the jewel head is designed to be adjustable to fit securely into the post. It's quite flexible and can be bent or straightened as needed. If you've bent the pin too much, you can easily re-adjust it by gently straightening it using a flat plier and then re-bend the pin to securely fit in to the post.

Hoop Earrings

Type of Hoop Earrings
Standard Hoop

The standard hoop is a timeless classic that most people wear regularly. Its easy-to-wear and remove feature makes it a convenient choice.

Clicker Hoop

The clicker closure offers the most secure fit, ensuring no fear of losing your earring. Its simple open, pull, insert, and click mechanism makes it effortless to wear.

Hollow Hoop

Hollow hoops are literally made in the hollowed tube. It is very lightweight and thin, simply open them pull, insert the post into the hollowed tube.

Hoop Size
Inner Diameter

The diameter refers to the measurement between the inner edges of a hoop or ring, excluding the jewelry's thickness.

How to Measure Your Hoop Size

Prepare a strip of paper and a marker pen. Holding the paper up to your ear, mark the measurement from the location of the piercing hole to the edge of your ear with a pen.

Measure the marked portion of the paper against a ruler by counting how many millimeters there are from the edge of the paper and where the line is marked.

Choose your hoop with the INSIDE-MEASUREMENT and now you know your hoop size.

If you want an accurate measurement, make sure to line up a strip of paper in a straight, horizontal line.
If you would prefer to have a loose-fitting, measure your earring placement at an desired angle.  Alternatively, you can also just add 1mm or 2mm to the size you got using the straight measuring method.

Are there other ways to measure a hoop size?

If you don’t want to take the measurement at home, then we recommend to visit local pierce shopy and ask your piercer for help.  Make sure you tell them the measurements of any designs attached to the jewelry so they can help you figure out if it’s going to fit well.
