The size of a needle is described first by its diameter and secondly by its length. The size of the new stitch is determined in large part by the diameter of the knitting needle used to form it, because that affects the length of the yarn-loop drawn through the previous stitch. Thus, large stitches can be made with large needles, whereas fine ...
In medicine, the Birmingham gauge specifies the outside diameter of hypodermic needles, catheters, cannulae and suture wires. It was originally developed in early 19th-century England for use in wire manufacture, and began appearing in a medical setting in the early 20th century.

The point eases the insertion of the hook through the material being crocheted and the groove makes it possible to pull a loop ...
A more hands-on method, there is the test swatch and the gauge swatch. Knitting a test swatch requires knitting the yarn into a small, roughly 4 in (10 cm) square textile of even stitches. [4] Comparing this with recommended needle sizes, yarn, and the knitter's own signature tension, allows for adjustments to all of these things.
Yarn weight is a factor; thicker yarns with less loft overall produce larger stitches than thinner yarns (reducing the number of stitches per width and length). Larger knitting needles also produce larger stitches, giving fewer stitches and rows per inch. Changing needle size is the best way to control one's own gauge for a given pattern and yarn.
This test uses a small "button" that has four to six short needles coated with TB antigens , either an old tuberculin or a PPD-tuberculin. The needles are pressed into the skin (usually on the inner side of the forearm), forcing the antigens into the skin. The test is then read 48 to 72 hours later by measuring the size of the largest papule or ...
