What Do You Know About the Anatomy of a Paintbrush?

Want to understand your brushes better? Learn their anatomy! Knowing a brush’s anatomy is the key to success. Let’s take a look at what it’s made of.

Brush Head

This is where the bristles are. They are the most important part and determine the brush’s character. The brush tip is the part that touches the surface you’re painting on. It can be pointed, rounded, or angled, and leaves a different mark depending on its shape. The belly is the widest part of the brush. It holds water and paint, and also determines the kinds of marks you can make with the brush.

Ferrule

This is the metal part that connects the brush head to the handle and holds the bristles firmly together. The quality of brushes can be judged by the type of bristles, the quality of the metal used for the ferrule, and how tightly the bristles are held in place. Cheaper brushes often have poor-quality glue, causing bristles to fall out and leave unwanted debris in your painting.

Handle, or the body of the brush, can be made of wood or plastic, and can be short or long, depending on the technique the brush is designed for. Brushes used on a horizontal surface, such as for watercolor and calligraphy, have short handles. Brushes for upright canvases have long handles, allowing for more distance between the canvas and your hand.

Size Marking

The size is printed on the first part of the handle. It is marked with numbers, starting at 000 (the thinnest), with sizes 1, 2 through 24 being the most common. Unfortunately, sizes are not standardized across manufacturers, so, for example, a size 10 does not necessarily mean the brush is 10 mm wide.

Series Marking

The series name is usually printed in this section after the manufacturer’s name. Since manufacturers offer many series, this information is essential for artists looking for a specific type of brush.

Code

The code contains letters and numbers that provide abbreviated information about the brush series and its specific shape within that series. When buying brushes online, just enter this code in the site’s search bar to find the exact brush you’re looking for. The handle usually also lists the country of origin.
