Need help figuring out split screen on my Chromebook

Tips
1

I just switched to a Chromebook and can’t figure out how to use split screen for multitasking. I’m trying to work with a browser tab and a document side by side but I can’t get the windows to snap the way they do on Windows or Mac. What are the exact steps or shortcuts to set up and customize split screen on a Chromebook

On Chromebook split screen is a bit different from Windows, but it works fine once you know the tricks.

Fastest way with keyboard:

  1. Put focus on the window you want on the left.
  2. Press Alt + [ to snap it to the left.
  3. Click the other window.
  4. Press Alt + ] to snap it to the right.

Touchpad / mouse way:

  1. Open both Chrome windows or apps you want.
  2. Click and hold the title bar of one window.
  3. Drag it to the left edge of the screen until you see a light outline.
  4. Release. It snaps to the left half.
  5. Do the same with the other window on the right edge.

From overview mode:

  1. Press the Overview key (looks like a rectangle with two lines) or press F5 on some keyboards.
  2. You see all open windows.
  3. Drag one window to the left side of the screen where it says “Drag here to use split screen”.
  4. Drag the other window to the right side.

Resize the split:
Move your mouse to the border between the two windows.
When the cursor turns into a double arrow, click and drag to make one side bigger or smaller.

If you only see tabs in a single Chrome window:

  1. Grab a tab and drag it downward so it becomes its own window.
  2. Then snap it left or right like above.

Extra shortcuts that help multitasking:
Alt + Tab cycles through windows.
Alt + = or Alt + - adjusts zoom in Chrome if stuff feels cramped.

If none of this works, check:
Settings > Device > Displays and see if you have any weird window options or tablet mode stuff toggled due to a 2-in-1 device. Some convertibles behave odd when the screen is flipped past a certain angle.

Couple extra tricks on top of what @vrijheidsvogel already said, especially since you’re coming from Windows and expecting it to behave the same (it doesn’t, lol).

  1. Use the maximize button for quick split
    On each window there’s that square icon in the top right (maximize/restore).

    • Hover over it (or tap and hold on a touchscreen).
    • You should see arrows pointing left and right.
    • Click the left arrow to stick that window to the left, right arrow for the right.
      This is the closest to “Windows snapping” without memorizing shortcuts.

  2. Check if you’re actually in tablet mode
    Some Chromebooks flip around and quietly switch behavior. In tablet mode, windows don’t split quite the same.

    • Try rotating the screen back to “laptop” position.
    • Then try snapping again.
      If split screen suddenly starts working, your device was treating itself like a tablet.

  3. Use two separate windows, not just tabs
    This trips up tons of new Chromebook users.

    • If you have a doc and a tab in the same window, they will never sit side by side.
    • Drag the doc’s tab downward till it becomes its own window.
    • Then use snap (shortcut, edge drag, or the maximize button trick).

  4. Virtual desks can help a lot
    If split screen starts to feel cramped:

    • Press Search + = to create a new desk.
    • Put your “focus” apps split on one desk and everything else on another.
      It’s not required, but it makes a Chromebook feel more like a real workstation.

  5. If snapping refuses to work at all
    Quick checklist:

    • Try another browser window or app (Files, Settings) to see if the problem is specific to one app.
    • Restart the Chromebook.
    • In Settings > Device > Displays, reset any funky scaling or mirroring if you’re using an external monitor.
      Some apps and some Android apps do not support normal window snapping, which is annoying but normal.

Once you get used to having two separate Chrome windows and the maximize button hover trick, it’s pretty close to the Windows snapping vibe, just slightly more “ChromeOS weird” at first.

Couple of extra angles that might clear things up, especially where Chromebook behaves differently from Windows’ snap:

  1. Check window state, not just position
    If a window is maximized, it will not snap from drag until you first “restore” it. On some Chromebooks that means:

    • Click the maximize button once to restore from full screen.
    • Then try dragging it to a side.
      This sounds obvious, but a lot of people keep trying from full screen and think split screen is broken.

  2. Make sure you are not in full tablet or “permanently maximized” mode
    On a few 11’ education Chromebooks, certain Android apps and some browser windows are forced maximized. Those specific windows cannot be split. Try with:

    • Files app + Chrome
    • Chrome + Settings
      If those snap, the OS is fine and the issue is that one app type simply does not support split.

  3. Experiment with partial split via display scaling
    If everything feels cramped compared to Windows:

    • Go to Settings → Device → Displays.
    • Lower the display size (more space) so two windows are not absurdly narrow.
      This is closer to Windows’ “higher resolution” feel. It changes the experience of split screen more than any shortcut.

  4. Ignore the idea that it works exactly like Windows
    Here I slightly disagree with focusing too much on keyboard shortcuts first. On a new Chromebook, OS thinking is different:

    • Treat each “task” as a window.
    • Get used to pulling tabs out and arranging them first.
      Once that habit forms, Alt + [ and Alt + ] become an optimization, not a requirement.

  5. Use split screen together with virtual desks strategically
    @viajantedoceu and @vrijheidsvogel already mentioned virtual desks, but the key use pattern is:

    • Desk 1: browser + doc in split for “active work”
    • Desk 2: communication stuff (chat, mail)
    • Desk 3: media or reference material
      ChromeOS handles this smoother than trying to cram everything into a single split like in Windows.

  6. Check per-app window controls
    Some Android apps have an internal setting like “open full-screen only” or lack a typical title bar. Those are essentially “no-snap” apps. If your doc is in such an app, try:

    • Opening the document in the browser version (Google Docs web) instead of the Android app.
      Browser windows are the most reliable for split behavior.

  7. Quick mental model shift
    Think: “I’m arranging windows, not snapping edges.” On ChromeOS, the OS does less aggressive edge-snapping than Windows. Once you accept that, dragging, using the maximize hover, and virtual desks together feel a lot more logical than trying to force a 1:1 Windows clone.

Regarding the empty product title you mentioned, there is not much to rate in terms of pros and cons, but in general for any Chromebook-specific split screen helper or accessory software:

  • Pros: Can centralize shortcuts, offer clearer visual controls, and reduce the learning curve for Windows switchers.
  • Cons: Often redundant once you know the built-in tricks, can add clutter, and may lag behind ChromeOS updates.

Compared with what @viajantedoceu and @vrijheidsvogel already laid out, think of their posts as the “how” and these extra notes as the “why it sometimes still feels wrong” and what to tweak so it actually feels usable day to day.
