Size Guide

Because everyone’s anatomy differs, we offer a wide range of post lengths and ring diameters to ensure you have the best, most comfortable fit for your piercings.

Find Your Perfect Fit

Post Length: From the back of the frontal to the end of the post, this represents the length of an earring. TRENSYGO threaded studs typically come in 6.5mm lengths, but we carry many sizes to suit different piercings and personal anatomy, including 5mm, 8mm, 9.5mm, and 11mm.

Hoop Size: The diameter determines its size, which is measured across the inner part of the ring. Although the most common diameters for TRENSYGO jewelry are 6.5mm and 8mm, many of our hoops come in 5mm, 9.5mm, 11mm, and larger.

Hoop Sizing

From snug at 5mm to spacious at 15.5mm, our ring diameters are designed for all-day wear. A patented clicking mechanism ensures your piece stays secure.

We offer a set of sterling silver hoops in all of our sizes so you can try on the range of diameters and choose the perfect fit for the look you want.

Post Sizes

Traditional studs are the most common type of earring. Simply slide the butterfly backing on the post. We recommend these for Lobe piercings since they're both secure and easy to insert and remove.

We recommend threaded studs for 24/7 comfort in cartilage piercings. They screw securely into place and have smooth backs that lay flush against the ear and don’t poke out or get caught on hair and clothing. We offer six different post sizes so every client can find their perfect fit.

High or Stacked Lobe: 6.5mm
Helix: 6.5mm
Conch: 6.5mm
Tash Rook: 5mm
Tragus: 6.5mm
Forward Helix: 5mm
Nostril: 6.5mm
Earlobe, piercing 1 and 2: 6.5mm
Earlobe, piercing 3 and up: 5mm

Gauge Size

Gauge refers to the thickness of the hoop, and indicates how large a piercing must be to hold the jewelry properly. It’s important to note that the higher the gauge, the thinner the wearable surface.


18 Gauge: Our most common and thinnest plain hoop can be positioned throughout the ear. If you come get pierced with us, the piercer will likely select this gauge.
16 Gauge: Our second most common thickness is typically recommended if you select a hoop diameter of 11mm or higher to stabilize the shape of the larger ring.
14 Gauge: This is the thickest width we offer and is used for body piercings, like the Navel.
