Thereof, which is bigger 14 gauge or 16 gauge piercing?
So higher numbers (like 16 gauge) are thinner than smaller numbers (like a 6 gauge). When discussing gauges, references to a “larger gauge” means bigger around, not a bigger number. That is to say that if you’re told that you need a larger gauge than 14, you need to look at 12 or 10 which are wider, not at 16.
Similarly, which is bigger 16 or 18 gauge piercing? In the U.S. an 18 gauge earring measures approximately 5/128-inch while a 16 gauge earring measures 3/64-inch, for a difference of 1/128-inch or approximately 0.0078 inches.
Also question is, which is bigger 14g or 16g?
The 14g is a larger barbell than the 16g by a fraction of an inch (0.013). Most piercers will have a preference between 14 and 16g for industrial piercings and while having a 14g means you can swap out for 16g jewelry you cannot do it the other way around without pain.
