Paintbrush sizes ?

Is this a funny question, or just in the category that Captain Obvious would answer?

I am looking for a small brush, (Really? sarcasm) what the frak is it with the numbers?

5/0 20/0 10/0?

i looked at 2 different 20/0 and here is where the confusion really got to me

One of the brissle lenghts was about 15mm long and 1 was 7mm long. So 20/0 isn’t the lenght but “width” i guess.

Now many, many years ago a friend painted RPG figurines and i swear his brush was 1/10th of a birds eyelash in width. What number would his be?

He was able to paint eyes in the slit of a visor. His skill was and i hope still is insane.

I am just about ready to crazy glue a cat’s wisker on a chopstick to use. What number would that be ?

Any help out there?

Masters, this Padawan need guidance.

Brush sizes are non-standard among different brands and have no reference to physical dimensions. The type of brush also adds to confusion. A size 0 Round brush will be larger than a size 0 Spotter, etc.

So Just like the Grit on sandpaper, varies from one compagny to another

As I’m sure you already know the higher the number the smaller the brush like wire gages [*-)], but a 10/0 does seem to be slightly diffrent between manufactures. Years ago I would buy a 10/0 and I swear the thing had 2 hairs, now I have to look at all of them at the store to see which one is the smallest. I have several “10/0” in my brush stash and each one of them is diffrent. Some of them I re-gaged I.E. trimed myself.

However, like anything else, you get what you pay for.

I don’t sweat the “must have” brush sizes. I have a variety of them and use them depending on what I need it for.
