Brush Size Control
Brush size control in Adobe Photoshop refers to the ability to adjust brush dimensions during active painting and editing work. Rather than accessing brush settings through menus or panels, Photoshop provides keyboard shortcuts that allow artists to modify brush properties in real time without interrupting their workflow. This method of control is particularly useful when working on detailed digital art, photo editing, or illustration projects.
Bracket Key Shortcuts
The primary method for controlling brush size in Photoshop uses the square bracket keys on a standard keyboard. The left bracket key [ decreases brush size, while the right bracket key ] increases brush size. This provides immediate visual feedback as the brush outline adjusts on the canvas. When combined with the Shift key, these same bracket keys control brush hardness—Shift+[ softens the brush edges, while Shift+] increases hardness. These shortcuts remain consistent across different Photoshop tools that use brushes, including the Paintbrush, Clone, and Healing tools.
Workflow Benefits
By enabling real-time brush adjustment without menu navigation, bracket key shortcuts maintain artistic momentum and precision. Artists can quickly switch between brush sizes to handle different details or coverage areas within a single painting session, or adjust hardness to create softer blends or harder edges as needed. This direct control method has become standard practice in professional digital art and photo retouching workflows.
