What You'll Need

What Is the Blob Brush Tool?

Illustrator's Blob Brush Tool (Shift-B) is used to draw expanded brushstrokes, and many designers consider it the go-to tool for line designs, character designs, or sketches.

To activate this tool, you can either select it from the toolbar or press the Shift-B keyboard shortcut.

What Does the Blob Brush Tool Do in Illustrator?

In contrast to the Paint Brush Tool (B), which draws brushes as paths, the Blob Brush Tool (Shift-B) draws brushes as filled shapes.

With a brushstroke (or any shape) selected, use the Blob Brush Tool (Shift-B) to add a new brushstroke, and it will unite with your selected shapes provided that the objects have an overlapping area.

Step 5

Drag the Fidelity slider all the way to the right to add extra smoothness to your brushstrokes, or move it all the way to the left to be more accurate in your input.

Step 6

The Size value determines the size of your blob brush in Illustrator. This is the second method that you can use to change the blob brush size in Illustrator.

Step 7

The Angle value determines the angle of the blob brush in Illustrator.

Step 8

The Roundness value determines the shape of the blob brush in Illustrator. Set it to 100% to get a perfectly round brush. Entering a number lower than 100% will produce a flatter brush.

Step 9

Using the drop-down menus, you can choose from a variety of settings for Angle, Roundness, or Size. This feature can be particularly useful if you own a graphics tablet.

  • Fixed: Sets a fixed angle, roundness, or size.
  • Random: Sets a variable angle, roundness, or size. For example, when the Size value is 10 pt and the Variation value is 10 pt, the diameter of your brush will randomly range between 0 pt and 20 pt, as shown in the following image.

  • Pressure: Set a variable angle, roundness, or size based on the pressure of the drawing stylus. This feature is available only for graphics tablet users. For example, when the Size value is set to 10 pt and the Variation value is set to 10 pt, the thickness of your brush will range between 0 pt and 20 pt, depending on the pressure that you apply with the pen tablet.

  • Stylus Wheel: Set a variable angle, roundness, or size based on manipulation of the stylus wheel. This feature is intended to be used with an airbrush pen that has a stylus wheel on its barrel and with a graphics tablet that can detect that pen.
  • Tilt: Set a variable angle, roundness, or size based on the tilt of a drawing stylus. This feature is available only if you have a graphics tablet that can detect how close to vertical the pen is.
  • Bearing: Set a variable angle, roundness, or size based on the bearing of the pen. This feature is available only if you have a graphics tablet that can detect the direction in which the pen is tilted.
  • Rotation: Set a variable angle, roundness, or size based on how the drawing stylus pen tip is rotated. This feature is available only if you have a graphics tablet that can detect this type of rotation.
