If you’re used to the brush tool in Photoshop, you might get a bit disappointed with the brushes in Illustrator. Well, at least that’s how I feel after working as a graphic designer for about 10 years.
The brush tool in Illustrator is not as powerful and convenient as in Photoshop. There isn’t a size option when you select the brush, but it’s super easy to change the size.
The key to changing brush size is to change the stroke size. You’ll notice that when you draw with the brush tool in Illustrator, it automatically selects the Stroke color instead of the Fill.
You can change brush size from the Properties panel, Brushes panel, or using keyboard shortcuts.
I’ll show you how!

Found it? This is what it looks like. Now you can choose one of the methods below to change brush size.
Method 1: Brush Options
Step 1: Click on the hidden menu on the Brushes panel and choose Brush Options.
This brush setting dialog box will pop up.
Step 2: Move the sliders to change the brush size and you’re ready to go. If you changing an existing brushstroke, you can click the preview box to see how it looks.
Note: If you already have some strokes on the artboard, when you change the size here, all stroke sizes will be changed. If you need to change the size of a specific stroke, check out method 2.
Method 2: Properties panel
Step 1: Select the brush you want to change size. For example, I selected the stroke in the middle and I want to make it thinner.
Step 2: Go to the Properties panel > Appearance > Stroke, click or type in a value to change the size.
The default size is usually 1 pt, and there are some common options you can choose when you click on the arrow. I just changed mine to 2 pt.
Method 3: Keyboard Shortcuts
With the brush tool selected, you can use the bracket keys to adjust the brush size. Press the [ key to decrease and ] key to increase the size of the brush.
You’ll see a circle around the brush when you press either key, that shows the size of your brush. This method is convenient when you’re drawing with different sizes of brushes. You can also use it to make dots instead of using the ellipse tool 😉
