The Size Guide for
Paintbrushes

Paintbrushes are produced in a variety of sizes, shapes, and types of bristles. In order to choose a brush that will best serve your painting needs, these elements should be considered.

Whether you select a paint brush with synthetic or natural bristles depends upon the type of paint you are planning to use. Paint brush bristles can also be characterized according to softness, firmness, and durability. Softer bristles can produce a smoother finish while firm and durable bristles perform better on rough surfaces.

Paint brushes are also available in several sizes to facilitate the many different facets of painting. The optimum brush size depends on the size of the area to be painted. Obviously, smaller brushes are well suited for small surfaces while larger brushes work well for large surfaces.

The working end of a paint brush typically has an angular or straight shape. Angle brushes are somewhat easier to use in sharp corners and on surfaces with irregular profiles. Conversely, straight brushes are well-matched for flat surfaces.

The paint brush guide shown below, matches up brush sizes and shapes with different aspects of painting. These are only intended to be recommendations with the goal of selecting a paint brush that is comfortable to hold and easy to use.

In the tables below:
A represents angle paint brushes
S represents straight paint brushes
