Here are some of the gauge sizes for more common body piercing sizes:
Lip Ring Gauge - 16 gauge, 5/16 inch (8mm) length is the most common size for lip rings after the piercing has fully healed. Initial lip piercings are usually done with a labret stud or captive ring that is 16 gauge and 3/8 inch or longer to compensate for swelling after piercing. When the lip piercing heals, most people can use a 5/16
Inch (8mm) length, or even a very short 1/4 inch (6mm) but not everyone! Again, this is a guideline. If your lip is thicker, you may need a longer length lip ring. Some piercers are also using 18 gauge for lip piercings, which is slightly thinner than 16 gauge. The only way to properly determine the lip ring size you need is to measure or consult your piercing professional!
Nose Piercing Gauge - The most common nose piercing gauge is 18 gauge. That is the gauge most piercers use for nose piercings. A nose screw or nose hoop are the best styles for initial piercings. It is best to use one of these until the nose piercing is completely healed. If you switch to a nose bone too quickly, the piercing may start to heal around the bulb at the bottom and cause problems. Nose studs that are bent into an L shape are not as secure as the nose screw. Many people want a smaller hole in their nose, so they go down to 20 gauge or 22 gauge which are thinner than 18 gauge. Some nose piercings are 16 gauge (thicker than 18 gauge), but they are less common and there are not very many 16 gauge nose rings available. We carry a large selection of nose bones, nose screws, bend to fit nose studs and nose hoops in 22 gauge, 20 gauge and 18 gauge.
Nose Stud Sizes-Some of our nose rings are available with different length posts. The most common nose post size is 1/4 inch (6mm) long. But some piercers use a slightly longer post (5/16 inch-8mm) for the initial nose piercing to compensate for swelling. This size works for some people, but others may find it uncomfortable after the nose piercing heals.
There is no right type of nose ring. The customer usually chooses what style they want (screw, bone, stud or hoop) based on personal preference, comfort, ease of use etc. We recommend that you consult with a local piercing professional if you are not sure how to use a certain type of nose ring. Some nose rings come in different lengths, diameters, etc. The size you need is based on where your piercing is placed on the nose and how thick your nose is, etc. The only way to properly determine the size you need is to measure a piece of jewelry that fits properly and use it as a guideline or consult your piercing professional!
Cartilage Earring Sizes- The most common gauge for a cartilage piercing is 16 gauge, unless pierced at Claire's or Walmart, etc. (or usually any place that uses a piercing gun). They pierce with a 20 gauge needle (best to ask what gauge they are using to be sure).
Many people want a smaller gauge hole in their ear than 16 gauge, so they go down to 18 gauge which is thinner than 16 gauge. 20 gauge & 22 gauge are the thickness of regular earring studs.
Cartilage hoop diameter is measured in a straight line across the center, inside the hoop. 1/4 inch diameter (6mm) is very tiny and may be OK for a tiny ear that is pierced close to the edge. 5/16 inch (8mm) is slightly larger and fits more people. 3/8 inch (10mm) is good for a piercing farther away from the edge of the ear. The only way to properly determine the size you need is to measure a piece of jewelry that fits properly and use it as a guideline! You can also wear labret studs, captive rings, circular barbells, spiral barbells, stud earrings, seamless rings, segment rings and curved barbells in your cartilage piercing.
Belly Button Ring Gauge - Most belly button piercings are done with a 14 gauge 1/2 inch (12mm-that is on the longer side) to compensate for swelling after piercing. When the piercing heals, most people can use a shorter barbell in 1/4 inch (6mm-for very shallow piercings), 5/16 inch (8mm) or 3/8 inch (10mm) length, but not everyone! Again, this is a guideline. If your piercing is shallow, you may need a shorter length barbell 1/4 inch (6mm). Deeper navel piercings may need a 7/16 inch (11mm), 1/2 inch (12mm), 9/16 inch (14mm). We even carry belly button rings with a long 5/8 inch (16mm) barbell. Many years ago piercers were using 16 gauge (which is slightly thinner than 14 gauge) so if your piercing is older, you may have a 16 gauge piercing. The only way to properly determine the size you need is to measure or consult your piercing professional.
