Watercolour brushes come in many different shapes, and each type creates its own unique effect on the paper. Some brushes are designed for large washes and soft backgrounds, while others are better suited to fine details, textures or expressive brushstrokes. In this guide, we go through the most common types of watercolour brushes, how they differ and what they are used for.

|---|---|---|
| Round | Pointed tip and rounded body | All-round painting, details and washes |
| Flat | Flat and straight shape | Backgrounds, straight strokes and large areas |
| Mop | Soft brush with high water capacity | Large washes and soft transitions |
| Liner / rigger | Long and thin tip | Fine lines and details |
| Fan | Flat and spread-out shape | Textures, grass and foliage |
| Water brush | Built-in water reservoir | Sketching and portable painting |

Liner / rigger watercolour brush
The liner brush, also known as a rigger brush, has a long and thin tip designed for creating flowing and controlled lines. It holds more paint than you might expect, allowing you to paint longer lines without dipping the brush as often.

Liner brushes are popular in landscapes, botanical painting and illustration, where precise and ultra-fine lines with a soft and fluid feel are needed.

Mop watercolour brush
Mop brushes come in different shapes but are known for their softness and high water capacity. They are large and soft watercolour brushes that can hold a lot of water and paint, making them popular for loose and soft watercolour paintings where you want to work quickly across larger areas without harsh brushstrokes.
When do you use a mop brush?
- large washes
- backgrounds and skies
- soft transitions
- loose and expressive watercolour painting
- holding a lot of water and pigment
Fan watercolour brush
The fan brush has a flat and spread-out shape where the bristles fan out like a handheld fan. It is mainly used to create texture, variation and lively effects in watercolour paintings.
When do you use a fan brush?
- grass and reeds
- foliage and bushes
- hair and fur
- clouds and textures
- special effects
Fan brushes are popular when you want to create more organic and dynamic brushstrokes without painting every detail separately.
Water brush for watercolour
The water brush has a built-in water reservoir in the handle, allowing water to flow directly into the brush tip while you paint. It comes in several different shapes and sizes, from pointed round brushes to flat brushes, depending on the type of expression and technique you want to work with.
When do you use a water brush?
- urban sketching
- travel and plein air painting
- quick sketches
- with watercolour pencils and watercolour crayons
Water brushes are especially practical when you want to paint easily and portably without bringing a lot of equipment with you.
Which watercolour brush should you choose?
If you are new to watercolour, you do not need a whole collection of brushes to get started. Many watercolour artists get far with a medium-sized round brush, as it works well for both details and larger washes.
A good starter set could include:
- a round watercolour brush for all-round painting
- a smaller liner or detail brush for fine lines
- a mop or flat brush for washes and larger areas
The best brush for you also depends on what you enjoy painting. Landscapes and loose watercolours often benefit from larger mop brushes, while illustration, botanical painting and detailed work usually require smaller and more precise brushes. Over time, many artists also expand their collection with more specialised brushes for specific techniques, subjects and styles.
