When it comes to painting, the shape of your brush tip can completely change how paint behaves on the surface. Each brush shape serves a unique purpose — from smooth washes to fine detail work. Understanding these differences helps artists achieve precision, texture, and expression in their work.
1. Round Brush
Best for: Lines, details, and controlled strokes
Round brushes have a pointed tip and a wide belly that holds a good amount of paint. They’re ideal for sketching, outlining, detailed work, and controlled washes. The size of the tip changes the width of the stroke easily with pressure.
2. Flat Brush
Best for: Bold strokes, edges, and filling large areas
Flat brushes have straight edges and a square tip, making them great for creating sharp lines or large color blocks. Perfect for acrylics, oils, or backgrounds in watercolor painting.
3. Filbert Brush
Best for: Blending and soft, rounded edges
A filbert brush combines the best of flat and round shapes — with a curved tip that allows smooth blending and softer strokes. It’s perfect for painting natural forms like petals, leaves, or portraits.
4. Fan Brush
Best for: Textures, blending, and special effects
Fan brushes have bristles spread out like a fan, ideal for soft blending or creating texture — such as grass, hair, or clouds. Great for both subtle and expressive techniques.
5. Angular (Slanted) Brush
Best for: Precise edges and curves
The angled shape makes it easy to paint sharp corners and dynamic strokes. Often used for floral work, lettering, and angled details in both watercolor and acrylic painting.
6. Mop Brush
Best for: Washes and blending large areas
Mop brushes have soft, rounded bristles designed to hold lots of water and pigment. They’re perfect for smooth, even washes and blending large areas without streaks. Often made with squirrel or synthetic squirrel hair for softness.
7. Rigger (Liner) Brush
Best for: Fine lines and calligraphy-style strokes
This long, thin brush was originally designed for painting ship rigging — hence the name. Ideal for continuous, flowing lines, signatures, and delicate details.
8. Fan Mop & Specialty Brushes
Best for: Effects and creative textures
These include variations like dagger, comb, or fan mops — each offering unique marks for expressive work, decorative art, or abstract textures.
Choosing the Right Brush
When selecting a brush, consider:
-
Medium: Watercolor, acrylic, or oil
-
Technique: Washes, detailing, blending, or texture
-
Material: Natural hair (like squirrel, sable, or hog) vs. synthetic
Each brush has its own personality — and mastering their uses opens new creative possibilities.
