Paint brushes from size â0000â to size 12. One feature of paint brushes is the wide variety of sizes. Generally, the size of a paint brush can be identified by a number, the larger the number the bigger the size. Size â0â is a very small brush and the sizes go up to at least size â40â. There are some exceptions to this sizing method.
