Understand your paintbrushes.
A brush is more than its shape. Learn how anatomy, hair, size and performance affect the marks you make-then use that knowledge to choose a brush for your medium and technique.
What is a paintbrush? A paintbrush is a tool made of hair or bristle set into a ferrule and handle, used to apply paint, ink or dye to a surface. The hair type, shape and size together determine how much medium it holds, how precise a line it can make, and which painting techniques it suits best. This guide covers anatomy, shapes, hair types, sizing and how to choose the right one for your medium.
01 · Know the parts
Brush anatomy
The parts of a brush work together: the head carries and delivers paint, the ferrule secures it, and the handle influences comfort and control.
Body
The middle of the hair that holds much of the paint or water while you work.
Toe & point
The toe is the tip of the hair; the point is its finest end. Together they influence precision and fine-line control.
Heel
The base of the hair secured inside the ferrule. It affects flexibility and resilience-and needs thorough cleaning.
Ferrule & crimp
The ferrule secures the hair to the handle. The crimp is the indentation that helps clamp the brush together.
Grip & handle
The part you hold. Its length, shape and material affect comfort, reach and control.
Care tip: Clean all the way to the heel where paint can collect. After cleaning, gently reshape the hairs to help preserve the point. Want to help protect your brushes over the long term? See what other artists are using ↗

03 · What the brush is made of
Hair & fibres
Brush hair may be natural animal hair or synthetic filament. Stiffness, softness, spring and absorbency vary by fibre and construction.
Stiff natural hair
Stiffer fibres resist bending and work well with heavier-bodied paints where pushing, moving and texturing paint matters.
Hog bristleBadgerSynthetic bristle
Soft natural hair
Soft hairs can hold water and create flowing strokes. Different hairs vary in point, spring, softness and capacity.
SableSquirrelGoatSheepPonyOx-ear
Synthetic fibres
Manufactured filaments can imitate a range of hair characteristics. They are often versatile, accessible and easier to maintain than delicate natural hair.
TaklonNylonInterlonSynthetic blends
Natural hair: common characteristics
Sable: soft and springy, with strong point and paint/water retention; often used for detail and blending.
Goat and sheep: soft, bushy hairs associated with water retention; often used for watercolor, ink and calligraphy.
Squirrel: very soft and absorbent, particularly suited to washes and calligraphy, but usually less springy.
Pony, ox-ear and camel mixes: can be useful for water-based work and broad coverage. “Camel hair” commonly refers to a blend of soft animal hairs, not necessarily hair from a camel.
Badger: can range from firmer at the base to softer and bushier at the tip; often used in blending and smoothing brushes.
Synthetic hair: common characteristics
Taklon: polyester filament that can be made in different refinements to imitate a range of natural-hair characteristics.
Nylon: a resilient, economical synthetic fibre used for smooth application.
Interlon: a nylon-derived filament designed with a curled tip to help the brush retain its shape.
Synthetic brushes cover a broad range, so do not assume every synthetic brush is equally soft, stiff, springy or absorbent. Check the construction and the brush’s intended use.
Specialty brush constructions
Flagged bristle: split tips on some hog bristles can help hold paint and work with higher-viscosity media.
Interlocked hair: filaments curl inward to help retain the head’s shape and control.
Sized hair: some brushes are temporarily stiffened during manufacture to protect their shape in transit. Dissolve the sizing gently before first use; do not bend or crack a dry sized head.
04 · Purpose-built tools
Specialty brushes
Some brushes are designed around a particular task, material or working tradition. Their construction can be as important as the shape of the head.

05 · Scale & reach
Brush sizing
Brush sizes are usually printed on the handle. The number generally describes the width of the hair at its base, but sizing is not perfectly standardized across manufacturers or brush shapes.
000

12
Smaller number ≠ identical size everywhere
Detail brushes may use very small sizes such as 20/0, 000, 00 and 0 before progressing to 1, 2, 3 and upward. Decorator and spalter brushes often use millimetres or inches. Compare the actual head dimensions when precision matters.
Handle length matters too. Short handles are commonly used for table-based work such as watercolor, ink and calligraphy. Long handles are commonly chosen for oil and acrylic painting at an easel, where longer strokes and greater working distance can help.
06 · Performance
Brush properties
These are separate qualities. A brush can be soft but springy, or loose yet highly absorbent. Choose based on the way you paint rather than assuming one brush is “best” at everything.
Stiffness
How strongly the hairs resist bending. Stiffer brushes can push and move heavy-bodied paint; softer brushes flex more easily.
Explore levels 1 to 5
- 1Very soft: Bends easily with light pressure; useful for delicate, flexible marks.
- 2Soft: Flexes readily, with little resistance against the surface.
- 3Balanced: Offers a middle ground between flexibility and resistance.
- 4Firm: Resists bending more noticeably and can move thicker paint with control.
- 5Very stiff: Strong resistance to bending; suited to pushing heavy-bodied paint and making textured marks.
Springiness
How well the brush head returns to its shape after pressure. More spring can support a defined point and controlled, consistent strokes.
Explore levels 1 to 5
- 1Very loose: Returns slowly or incompletely; creates softer, more expressive marks.
- 2Low spring: Some return after pressure, but the head remains relatively flexible.
- 3Moderate spring: A balance of shape recovery and flexibility for general control.
- 4High spring: Returns readily to shape, supporting consistent strokes and a defined point.
- 5Very springy: Snaps back strongly and maintains its shape under repeated pressure.
Water retention
How much water the brush holds within its head. It affects how long a water-based stroke or wash can continue before reloading.
Explore levels 1 to 5
- 1Very low: Holds little water; expect to reload frequently during washes.
- 2Low: Carries a limited amount of water for shorter strokes and smaller areas.
- 3Moderate: Holds a useful amount of water for a mix of detail and medium-length strokes.
- 4High: Carries more water for longer strokes and broader passages before reloading.
- 5Very high: Holds substantial water for extended washes and fluid, continuous strokes.
Paint retention
How much paint the brush can carry and release. Good retention can support smoother, more consistent application with fewer reloads.
Explore levels 1 to 5
- 1Very low: Carries little paint at a time and needs frequent reloading.
- 2Low: Holds a modest amount of paint for shorter strokes or small details.
- 3Moderate: Provides a balanced paint load for everyday coverage and control.
- 4High: Carries a generous amount of paint for smoother coverage with fewer reloads.
- 5Very high: Holds a large paint load for longer strokes and broader, more continuous coverage.
Versatility
How well a brush’s combined qualities serve different media, techniques and tasks. A specialist brush may excel in one job instead.
Handle comfort
Grip shape, length and material affect control and fatigue. Ergonomic shapes or a flat edge may improve comfort and prevent rolling.

A quick buying checklist
Match the brush to the medium and the viscosity of the paint.
Choose a head shape that naturally makes the marks you need.
Select a size appropriate to the scale of the artwork and detail.
Check the point and the overall cut for stray or uneven hairs.
Check that the ferrule is firmly attached and does not wobble.
Consider comfort and handle length for your usual painting position.
Care affects performance. Gentle handling, suitable cleaning and reshaping the head after use help a brush retain its shape. Delicate natural hairs may need especially careful treatment.
