The wall of a 20-gauge needle is generally 0.006 inches thick. In medicine, the gauge of a needle normally refers to its outer diameter, or the size of the puncture hole it makes. The gauge of a needle is inversely proportional to its size. In other words, a 16-gauge needle is thicker than a 20-gauge needle, and a 24-gauge needle is thinner than a 20-gauge needle. The thickness of a needle has little relationship to its length.
