All brushes have a variable size that can be changed.

You can change the brush size in several ways:

Using the Size slider in the tool options. Pencil, Paintbrush, Eraser, Airbrush, Clone, Heal, Perspective Clone, Blur/Sharpen and Dodge/Burn tools have a slider to vary the brush size.
By using the default shortcut keys for changing a tool's size:
- Decrease size by 1: [
- Increase size by 1: ]
- Decrease size by 10: {
- Increase size by 10: }
By using the default mouse scrollwheel actions for changing a tool's size:
- Decrease size by 1: Ctrl+Alt+Scrollwheel Down
- Increase size by 1: Ctrl+Alt+Scrollwheel Up
By configuring the mouse wheel behavior in the Input Controllers preferences:

11. Click the OK button of the main window of Preferences.
After these somewhat long explanations, you can use your mouse wheel to vary brush size. For example, choose the pencil tool with the Circle brush. Set the pointer in the image window, and use the mouse wheel in both directions to see the Circle shrinking or stretching.
