01

Understanding Gauge (Post Thickness)

The smaller the gauge (G) number, the thicker the post. Please choose according to the condition of your piercing hole.

Gauge Comparison
GAUGE DIAMETER DESCRIPTION
20G 0.8mm Common fashion earrings.
18G 1.0mm Wanna standard. Ideal for stable piercings and men.
16G 1.2mm Body piercing specification with a strong presence.
STYLIST'S NOTE The difference between 20G and 18G is only 0.2mm. Most people can wear them smoothly without pain, so please rest assured.
02

Post Length

Having about +2mm of extra length compared to your earlobe thickness will provide a comfortable fit without feeling tight.

Post Length
SHORT / Approx. 6mm

For those with thinner earlobes or areas like cartilage where a snug fit is desired.

STANDARD / Approx. 8-10mm

This is Wanna's recommended standard length, allowing even those with thicker earlobes to wear them comfortably.

03

Hoop Inner Diameter

For hoop types, the "inner diameter" (the space for your ear) rather than the outer diameter determines the style.

Inner Diameter
INNER SIZE STYLE IMAGE
8mm or less A tight, minimalist style that hugs the earlobe.
10-12mm A good amount of space. The most popular standard size.
14mm or more A dynamic, fashionable, and elegant impression.

Frequently Asked Questions

Q. How do I know my earlobe thickness? A. Place a ruler perpendicular to your piercing hole and check in a mirror for accuracy. The average Japanese earlobe thickness is around 6mm, but Wanna primarily designs with an ample 8-10mm.
Q. What if my earlobes have different thicknesses? A. Choose based on the thicker earlobe. Having extra space is fine, but pressure can cause inflammation or other issues.
