However, the basic thing to keep in mind is understanding how sizes are created. Brush families are built in sizes, based on the medium usually, ranging from zero sizes up to the mid-20s or 30s. So, the length of the tuft, size of the ferrule increase with each step up in number.

Watercolor brushes with Dynasty go from 20/0 to 36! A nice fat jumbo round as in the Black Gold 206 round series. Dynasty has been using this sizing system for 83 years.
In Europe, the brush companies use a different standard, where a size #24 is close to the U.S. size 12. Asia has other standards and sizing altogether.
According to our Vice President, Jeff Mink, "It's important to consider the actual size of the brush, not just the size imprinted on the handle." If you're shopping for brush sizes recommended by another artist, especially if you're unable to see the brushes in person, ask for the diameters or widths of the ferrule so you can find a similar size.
