The general principal for choosing needle sizes goes like this. For thinner finer fabrics the number needs to drop. And for thicker fabrics the number goes up.

Finer the fabric, lower the number of the needle.

The most common sizes used among the universal needles  are 12 and 14. This is the American number system.

For the most common needles European metric needle sizes number needles from 60 to 120.

So the first number on the needle is the American number system and the next European metric sizing.

For both numbering systems, the lower the number the finer the needle and the higher the number the larger the needle.

Are sewing machine needles marked with size?

Each sewing machine needle will have the sizes embossed on them. But the size of the markings will be very small and difficult to read. The covers of the needles will also have the machine sizes in bigger lettering. The American numbering system and European numbering system will be marked on them for easy identification.

One peeve I have about these needles is that it is difficult to read the writing on them. Unless you store them in their covers it is mighty impossible to read the numbers unless you have a magnifying glass or a 20 year old’s vision.
