When you’re working with the Brush Tool in Photoshop, you’ll need to know how to change the brush size quickly. There are various ways to change the size of your brush, but the best way to do it is with the steps outlined below.
The easiest way to change the brush size in Photoshop is to use the [ or ] keys on your keyboard. The left bracket key will scale the brush up in size, while the right bracket key will decrease the size. This handy shortcut works well to quickly change your brush size as you work.
Now, this doesn’t even cover the tip of the iceberg. There are several other ways to change the brush size in Photoshop, using keyboard shortcuts, your mouse, and good old fashion manual sliders. No matter what your style is, there’s a brush resizing shortcut you’ll love, and this post shares all of them. Let’s get started!
3 Best Ways To Change The Brush Size In Photoshop
Below are three of the best ways to alter brush sizes, starting with the most versatile option.
1. Changing The Brush Size With Your Mouse
This first method varies slightly depending on whether you use a Mac or PC. On a Mac, this shortcut is Option + Control + Click & Drag Horizontally. On a PC, the shortcut is Alt + Right Click + Drag Horizontally.
When dragging to the left using this shortcut, the brush will increase in size. By dragging to the right, the brush will decrease in size. This is one of the fastest ways to change the brush size while you work, but it takes some shortcut memorization.
To sweeten the deal, you can also change the brush feather using the same shortcut. Rather than dragging left or right, you can drag up or down to change the brush’s softness. You can easily tell how your brush will look based on the red highlight that appears when using this shortcut.
2. Changing The Brush Size With Your Keyboard
The second way of changing the brush size doesn’t allow you to change the brush’s feather, but it works well for quickly scaling your brush. By pressing the [ or ] keys on your keyboard, you can quickly increase or decrease the size of any brush in Photoshop. To make life even easier, you can hold down either of these keys to scale large amounts with less effort.
3. Using The Brush Preset Panel To Change The Brush Size
The third and final way to change your brush size is with the sliders found within the Brush Preset Panel. You can access this panel in one of two places. The first is in the upper settings bar when the Brush Tool (B) is active. By opening this panel and adjusting the Size slider, you can easily make manual adjustments or type in precise values.
Alternatively, you can open this same panel in your canvas while you work. While your brush tool is active, right-click on your canvas to open the brush presets panel. Here you can once again change the size slider and quickly change the size of your brush.
With both of these methods, you can also use the hardness sliders to change your brush’s feather on the fly.
How To Change The Default Brush Size In Photoshop
You may find yourself using a certain brush size regularly and would love to have that size set to your default setting. Unfortunately, you can’t set a default brush size across all your brushes, but you can create a default brush size for individual brushes.
To set a default brush size in Photoshop, open the Brush Settings panel and pick the desired size for your brush. Then click on the hamburger menu and choose “New Brush Preset.” In the dialogue box that appears, check off the “Capture Brush Size In Preset” option and click OK to save the brush. Now you have a default size saved for your new brush.
Depending on your workspace, the Brush Settings Panel may not be in your toolbar. If that’s the case, go up to Window > Brush Settings to reveal the panel.
The settings shown in your brush panel will vary depending on the brush you have selected. Once you make any adjustments to the brush in the brush settings panel, they’ll be applied to your active brush, but they won’t be saved. That’s why after you adjust the size of the brush, you need to create a new brush preset.
Clicking on the hamburger menu and going to “New Brush Preset,” you can save your current settings as a new brush to use later on.
A new dialogue box will appear, allowing you to rename your new brush if you wish. The most important part here is that you check off the “Capture Brush Size in Preset” option. Without this, you will not have a default size saved for your new brush.
After the brush is saved, it will appear as a new brush at the bottom of the Brush Preset Panel. Now when you select that particular brush, no matter your prior brush size settings, it will reset the brush size back to the default value you’ve chosen.
So now you know three different ways to change the brush size in Photoshop, along with a helpful option to set a default brush size for new brushes. The right resizing shortcut will depend on your editing style, but I prefer the click and drag option the most. Since you can change the brush size and hardness all in one click, it’s the most efficient way of doing things.
With that said, remembering some keyboard shortcuts can be challenging, so the [ or ] keys and the Brush Preset Panel offer some other worthy alternatives to brush resizing.
