All brushes have a variable size that can be changed.
La dimensione di un pennello può essere cambiata in diversi modi:
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 configuring the mouse wheel behavior in the Input Controllers preferences:
Nella finestra principale di GIMP, fare clic su → .
Nella colonna a sinistra della nuova finestra, selezionare → .
The Additional Input Controllers preferences are displayed with two columns: and .
Nella colonna , fare doppio clic sul pulsante .
The Configure Input Controller dialog opens.
In the left column Event, select the entry Scroll Up.
Click the button (at the bottom middle of the list).
The Select Controller Event Action dialog opens.
In the Action column, expand the item.
In the left column Action, select Tool's Size: Increase Relative, then click the button.
Now the Scroll Up event is associated with the action tools-size-increase-percent.
Chiudere la finestra.
With the same method, configure Scroll Down to be associated with Tool's Size: Decrease Relative.
Click the 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.
By configuring the behavior of the Up and Down arrow keys of the keyboard:
Il metodo è simile a quello usato per la rotellina del mouse. Le uniche differenze sono:
In the column Active Controllers, double-click Main Keyboard.
In the column Event, edit the entry Cursor Up for the first key, and Cursor Down for the second key.
Then, use the Up and Down arrow keys of the keyboard. The result is the same as with the mouse wheel.
