Choosing Your Paintbrush by Aga Czech

The Right Paintbrush

When I first began painting, I underestimated the importantance of choosing the right paint brush. This article will focus on the tuft 'shape' of the paint brush and how it corresponds to each different different use and desired painting technique

The material that the paint brush hairs are made of, how they are bunched together, their length and shape all affect the characteristics of the brush.
Here is a list of the duties of some of the most popular brush shapes:


  • A squared-off brush.


  • Brush length twice as long as width
  • Use for backgrounds and details.
  • Use for covering large areas
  • blending


  • Width equal to length Allow for the most control
  • Great for coverage
  • Blending


  • The Filbert's shape can vary from a flatter brush with a rounded outer edge to an oval shape.
  • The Cat's Tongue shape comes to point for more control.
  • A multi tasking painting brush.
  • This brush can take the place of a round or flat depending on the way the artist holds the brush.

Round Brushes:

  • Primarily used for detail and working in small spaces.

Standard Round:

  • Use for shaping, details, and outlining.

Pointed round:

  • Use for retouching, finishing touches and details.
  • Pointed tip for coloring.
  • With a high reserve, this brush is widely used for watercolours
  • Worn rounded: Avoids “rounding”.

Script, Liner & Detail:

  • Script: The longest hair tufts. Holds the most paint.
  • Liner: The mid length hair tufts. Compromises between fine detail and longer flowing strokes.
  • Detail: The shortest hair tufts Offers the most control


  • The Fan paint brush is a thin layer of bristles spread out in the shape of a fan.
  • Fan brushes are generally used for blending and feathering colors.
  • Fan brushes can be used for painting trees, branches, grasses and detail.
  • It is popular for painting hair with its ability to paint multiple flowing strands in a single stroke.


  • Usually larger brushes favored by watercolorists, but also used with oils and acrylics.
  • Used for making large washes.
  • Used for blending and shading with oils.
