A needle system is a group of needles made to fit specific sewing machines. All needles in a system are of the same length and shank size, but are of various diameters. Lower size numbers are narrower or thinner needles used for lighter materials. Higher size numbers indicate a needle of thicker diameter, used for heavier materials. Match your needle system to your machine, then the size of the needle to the product you are sewing. You should also consider the thickness of the thread you are using when choosing needle size.
Almost all sewing machines designed for home (or domestic) use take the same flat shank needle system. It is called 130/705, HAx1 or 15x1 depending on the manufacturer.
