Rectangle for Mac

What Rectangle does

Rectangle is a free utility that makes arranging app windows fast and predictable. It provides keyboard shortcuts to move and resize open windows, and it can snap windows to designated areas of your screen so you can work with multiple apps or documents efficiently.

Getting started

Installation and setup are simple. After launching Rectangle, you'll see a collection of predefined hotkeys that perform common window actions. These presets work immediately, so you can start snapping and resizing without extra configuration.

Customizing shortcuts

If you prefer personalized controls, you can record your own custom hotkeys to match your workflow. Create shortcuts for common positions and sizes — for example, assign keys to place a window in a corner, stretch it across half the display, or center it on the desktop.

• Snap a window to the right half of the screen
• Move a window into the top-left quadrant
• Center a window on the display
• Resize a window to fill the entire screen

Tips for keeping shortcuts organized

With many available shortcuts, it’s easy to lose track of them. Consider grouping related actions (positioning, sizing, centering) and documenting your custom keys in a single note or reference file. You can also limit the number of shortcuts you actively use to the ones that speed up your common tasks.

Who benefits most

Rectangle is particularly useful for people who juggle several windows at once — developers, writers, designers, and anyone who needs to switch between apps quickly. While the variety of features might feel overwhelming at first, the app’s straightforward interface and optional customization make it a practical tool for everyday productivity.
