Display setup
Before configuring Rectangle, set your display arrangement in System Settings → Displays → Arrange. Drag the display thumbnails to match your physical layout. Rectangle respects this arrangement when moving windows between screens.
Move windows between displays
The default Rectangle shortcuts for display switching are:
- ⌃⌥⌘→ — Move to Next Display
- ⌃⌥⌘← — Move to Previous Display
These move the active window to the adjacent display and resize it proportionally.
Pro workflow: Move a window to the next display (⌃⌥⌘→) and immediately snap it (⌃⌥←) to fill the left half — all without touching the mouse.
Multi-display layouts
A common layout for developers using Rectangle App:
- Primary display: Editor (Left Two-Thirds) + Terminal (Right Third)
- Secondary display: Browser (Left Half) + Documentation (Right Half)
Set this up once and recall it in seconds with four key presses. Rectangle Pro adds the ability to save named multi-display presets and restore them with a single shortcut.
Frequently asked questions
Does Rectangle support three or more monitors?
Yes — Rectangle cycles through all connected displays with the Next/Previous Display shortcuts. The free tier handles any number of monitors.
Can I snap to the same position on every display at once?
Not simultaneously in the free version — you snap one window at a time. Rectangle Pro's display presets let you save and restore a full multi-display arrangement with one action.
Does Rectangle work with Apple's Sidecar?
Yes — Sidecar creates a virtual display that macOS treats like any connected monitor. Rectangle App can move and snap windows to it normally.
