How to Use Split Screen on a Chromebook

What is split screen on a Chromebook

Split screen is a ChromeOS window management feature that pins one window to the left or right half of the display while leaving the other half available for a second window. When you snap a window, ChromeOS shows a thumbnail strip of your open apps so you can fill the empty side without opening the launcher or cycling through tabs.

The feature works with every kind of app you can run on a Chromebook: browser windows, Android apps, Linux apps, and the built-in Files app. It is especially useful for comparing documents, taking notes while reading, or watching a video while browsing. The mechanics are the same whether you are on a clamshell or a 2-in-1 Chromebook in tablet mode.

• Snap left or right: drag a window to the edge of the screen
• Fill the remaining side: choose a second app from thumbnails
• Resize: drag the divider between the two windows
• Exit: drag the divider all the way to one edge or press the window's unmaximize button

Keyboard shortcuts for split screen

The fastest way to snap a window without touching the trackpad is to press the Overview key (the key with a square and two vertical lines, usually in the top row) together with the left or right arrow key. The active window snaps to that side, and the rest of your open windows appear as thumbnails on the other side.

You can then press Tab or use the arrow keys to select the second window and press Enter to fill the remaining half. This works even when you have many windows open, because ChromeOS filters the thumbnails to only the windows you have used recently. After you snap, you can switch focus between the two windows by holding Alt and pressing Tab, or just click on the one you want to use.

Using the maximize button to snap

Every ChromeOS window has a maximize button between the minimize and close buttons. If you hover over the maximize button, a small layout menu appears with options for the left half, right half, or full screen. Choose left or right and the window snaps into that half.

One advantage of this method is that it works even when the window is not in the foreground. The hover menu also shows a preview of where the window will land, which can help you avoid surprises. After the first window snaps, the thumbnail strip appears so you can pick the second app.

Resizing and exiting split screen

Once you have two windows side by side, you can drag the vertical divider between them to adjust how much space each window gets. This is useful when one app needs more room, such as a spreadsheet, while the other just needs a narrow column for a chat window or a note.

To exit split screen, drag the divider all the way to the left or right edge, or click the unmaximize button (the same button you used to snap) on either window. The other window stays at its previous size, and your arrangement returns to normal. You can also press the Overview key and drag the window away from the edge to unsnap it.

How screen size affects split screen

Split screen is most comfortable on Chromebooks with larger displays. On an 11-inch or 12-inch screen, each half is about the width of a smartphone in landscape, which is fine for reading but can feel cramped for heavy typing. On a 14-inch or 15-inch display, each half is wide enough for a document and a browser side by side without constant horizontal scrolling.

If you mostly multitask with two apps at once, a 14-inch Chromebook or a 15-inch model gives you the most usable space. A 13-inch Chromebook is a compromise if you need portability and still want a reasonable split view. If you often connect an external monitor, split screen works the same way on the external display, and you can have two windows snapped on the built-in screen and another two on the monitor.

• 11-inch: each half is narrow; fine for reading or quick reference
• 13-inch: comfortable for two apps when one is a chat or note
• 14-inch and up: both halves are wide enough for documents and browsing
• External monitor: snap-two-per-display works independently on each screen

Split screen in tablet mode

When you fold a 2-in-1 Chromebook into tablet mode, split screen still works, but the gestures are different. You can drag a window from the top to the left or right edge of the touchscreen, and ChromeOS will snap it. The thumbnail strip then appears so you can tap the second app.

In tablet mode, you can also use the overview gesture by swiping up from the bottom to see all open windows, then dragging one to a side. Because there is no physical keyboard, the Overview key shortcut is not available, so the drag method is the primary way to snap. The divider between the two windows is wider in tablet mode, which makes it easier to drag with your finger.

Alternatives to split screen

Split screen is not the only way to multitask on ChromeOS. You can also float a small window on top of another with picture-in-picture for videos, or use virtual desktops to organize different task groups on separate screens. Picture-in-picture is available for most video players, including YouTube and many Android apps.

For three or more windows at once, you can tile them manually by dragging each corner, though ChromeOS does not have a built-in three-column snap. A practical alternative is to use split screen for the two main windows and keep a third window on top with picture-in-picture. Virtual desktops are a good choice when you want to separate work from personal tasks without closing apps.

What to look for in a Chromebook for split screen

Split screen itself works on every Chromebook, regardless of processor or memory. The experience depends mostly on display size and resolution. A larger screen with a resolution of 1920x1080 or higher gives each half enough pixels to show a full document or web page without zooming out.

If you plan to use split screen regularly, choose a Chromebook with at least 8GB of RAM. Running two apps side by side, especially a browser with many tabs and an Android app, uses more memory than a single full-screen app. See how much RAM you need for a longer explanation. A Chromebook Plus model often includes a higher-resolution display and more capable processors, both of which make split screen feel smoother.

What to pick for your split screen needs

Questions

Can I use split screen with Android apps?

Yes. Android apps run in windows that support snapping just like any other ChromeOS window. Drag the app window to the edge or use the maximize button menu, and it will snap alongside another app.

Does split screen work with Linux apps?

Yes, with some caveats. Linux apps that support window resizing can be snapped like other windows. However, some Linux apps may not respond to touchpad gestures or may have quirks with the maximize button. You can still drag a Linux app window to the edge to snap it.

Can I have more than two windows in split screen?

ChromeOS natively supports two snap positions: left and right. For a third window, use picture-in-picture mode or float a window on top. You can also use virtual desktops to keep several snapped pairs on separate screens.

How do I turn off split screen?

Drag the divider between the two windows all the way to the left or right edge, or click the unmaximize button (the same button you used to snap) on either window. The other window returns to its previous size.

Does split screen work on a Chromebook with a small 11-inch screen?

Yes, it works, but each half is quite narrow. You can still use it for reading or quick reference, but for comfortable side-by-side work, a 14-inch or larger display is better.

What is the keyboard shortcut for split screen?

Hold the Overview key (the key with a square and two vertical lines) and press the left or right arrow key. The active window snaps to that side, and you can then choose a second window from the thumbnails.
