How to split screen on Mac with custom window layouts
Arrange Mac windows with the placements you use every day, then add custom layouts when the usual halves and corners no longer fit the work.
To split screen on a Mac in a way that supports real work, start with the windows you need to see at the same time. The shape of the screen comes second. Write down the two or three windows that keep competing for space, then decide which one needs the most attention.
Mac window snapping can place a browser beside a narrow notes column, an editor beside a terminal, or a shared document beside a communication window. Each case needs a different window layout, so one universal grid rarely stays useful.
Use the built-in placements first
Left half, right half, full screen, and center cover most quick changes. Mise also maps the four corners to U, I, J, and K. Their positions match the keys on the keyboard, which makes the layout easier to remember.
Keep these placements available even after you create custom zones. They are useful when a temporary task does not belong to a saved workspace.
Build a custom layout only after you notice yourself resizing the same group of windows more than once.
Turn the repeated arrangement into zones
Mise draws custom zones on a 12 by 12 grid. A zone must be at least two grid cells wide and two cells high, which prevents saved areas that are too small to use. Every custom zone also needs a shortcut before it can become part of the active layout.
The example below gives the main window three fifths of the screen. Two smaller zones share the remaining space. This works well when one task needs sustained attention and two supporting windows need to remain visible.

notes or documentation Secondary
terminal or communication
Give the zones a stable shortcut pattern
A shortcut should describe location rather than the app that happens to use it today. A left reading zone may hold a browser now and a document tomorrow. Keeping the shortcut tied to the position means the same command still makes sense.
Mise shortcuts act on the focused window. When Mise is focused, the shortcut moves Mise. When another app is focused, it moves that app. The default full-screen shortcut is ⌃⌥↑. Built-in shortcuts can be edited, and each custom zone receives its own required shortcut.
Use drag snapping when the mouse is already in your hand
Keyboard placement is quickest when the destination is already known. Drag snapping is useful when you are moving a window manually and want Mise to finish the placement. The three response levels change how close the pointer must get before snapping activates:
- Balanced keeps the activation area close to the screen edge.
- Responsive makes common edge placements easier to trigger.
- Quick grab starts reacting farther from the edge.
Hold Shift while dragging whenever you want to suppress snapping for that move. This gives you a temporary exception without changing the saved sensitivity.
Keep the layout small enough to remember
Save the zones that support a repeated task. Leave one-off arrangements to the built-in placements or manual resizing. A shorter list makes each shortcut easier to recall and reduces the chance of sending a window somewhere unexpected.
