How To Split Screen on Laptop

June 30, 2026

To use split screen on your laptop, you can either “snap” windows to the sides of your screen using your mouse or access built-in window management menus. This allows you to view and work in two or more applications side-by-side.

How to use split screen on Windows

Windows allows you to quickly snap apps using drag-and-drop mechanics or keyboard shortcuts.

Method 1: Drag and Snap

Click and hold the top title bar of your first application.
Drag the window to the far left or right edge of your screen until you see a translucent outline appear.
Release your mouse to snap the window to that half of the screen.
Click on another open app on the opposite side to fill the remaining half.

Method 2: Keyboard Shortcuts

Click on the window you want to move.
Press the Windows Key + Left Arrow to snap it to the left, or Windows Key + Right Arrow to snap it to the right.
Select another open window for the empty side when prompted.

Pro Tip

If you use split screen regularly, learn the keyboard shortcuts instead of dragging windows with your mouse. On Windows, Windows + Left/Right Arrow instantly snaps windows into place, while on Mac you can hover over the green window button to enter Split View. These shortcuts save time and make multitasking much more efficient.

Splitting Into More Than Two Windows

Windows also supports quarter screen layouts. Use Windows key + Up Arrow after snapping a window to a half, which moves it into a quarter of the screen, allowing up to four apps visible at once.

How to split screen in laptop without windows key

To split your laptop screen without using the Windows key, use your mouse or trackpad to drag an open window’s top title bar to the far left or right edge of your screen. When a transparent outline appears, let go to snap it into place, then pick your next app.

Using the Mouse (Drag and Snap)

Half-Screen Split: Click and hold the top bar of your app window, then drag it all the way to the left or right side of the screen until you see a clear box outline appear. Let go of the mouse button to snap it. [
Corner Split (Quarters): Drag the window into any of the four extreme corners of the screen to fill just one-quarter of the workspace.
Select the Second App: After the first window snaps, your other open apps will show up as small pictures on the other side. Click one to fill the empty space.

Using the Windows 11 Snap Menu

Hover your mouse pointer over the Maximize button (the small square icon at the top right corner of your active window).
A small menu showing different grid layouts will pop up automatically.
Click the exact section or side where you want your app to go, then choose your second app for the remaining space

How to Use Split Screen on a MacBook

macOS uses a feature called Split View to tile your windows side-by-side using the maximize button.

Method 1: Using the Green Button

Hover your mouse over the green “fullscreen” icon (with the outward arrows) in the top-left corner of your app window.
A drop-down menu will appear.
Select either Tile Window to Left of Screen or Tile Window to Right of Screen.
Your screen will split. Click another open app on the other side of your screen to pair them together.

Method 2: Click and Hold

Click and hold the green maximize button in the top-left corner of the window.
The window will shrink. While still holding down, drag the window to the left or right side of the screen.
Release the app and select your second window for the other half.

To exit Split View at any time, move your mouse to the top of the screen and click the green button again, then select Exit Full Screen.

How to plit screen on Laptop and Monitor

To use your laptop and an external monitor as a split or extended workspace, plug the monitor into your laptop using an HDMI, DisplayPort, or USB-C cable. Press the Windows Key + P and select Extend. Then, click and drag open application windows to move them freely between your laptop screen and the external monitor.

Connect and Extend Your Displays

Plug in the cable: Connect your monitor to a matching port (HDMI, USB-C) on your laptop and turn the monitor on.
Open Project menu: Press the Windows Key + P on your keyboard.
Select Extend: Choose Extend so your monitor acts as extra screen space instead of mirroring your laptop.
Arrange screens: Right-click your desktop, select Display settings, and drag the display boxes so their layout matches your physical desk setup.

Snap Windows on Each Screen

Side-by-side split: Click and hold the top title bar of a window, then drag it all the way to the far left or right edge of either screen until a transparent outline appears.
Keyboard shortcut: Select any window and press Windows Key + Left Arrow or Right Arrow to snap it to half of that specific display.
Corner split (Quarters): Drag a window into any corner of your monitor or laptop screen to snap it into a quadrant.
Snap Layouts (Windows 11): Hover your mouse over the maximize button in the top-right corner of any window and pick a preferred grid layout.

Using Snap Layouts on Windows 11

Windows 11 introduces an advanced menu to choose from multiple grid layouts instantly.

Hover Menu: Move your mouse cursor over any window’s Maximize icon (the square next to the close button).
Select Grid: A pop-up panel will display four to six different layout configurations.
Choose Position: Click inside one of the layout zones to send your current window to that exact spot.
Keyboard Shortcut: Alternatively, press Windows Key + Z to open the layout menu immediately using your keyboard.

Using Mission Control on Mac to swap split-screen apps

You can use Mission Control to easily switch, swap, or rearrange apps already in Split View.

Open Mission Control: Swipe up with three or four fingers on your trackpad, or press the F3 key.
View Spaces: Look at the top of your screen to see your desktop spaces and existing Split View pairs.
Swap Apps: Drag a different open window from below and drop it directly onto an existing Split View pair to swap it out.
Exit Split View: Hover over the split-screen thumbnail at the top and click the arrows icon that appears to release the windows.

What Is Split Screen and Why Use It?

Split screen divides your laptop display into two (or more) sections, each running a separate app or window at the same time. It is especially useful for:

Comparing two documents or spreadsheets side by side
Following a video tutorial while working in another app
Drafting an email while referencing a webpage
Multitasking during research, writing, or data entry

Adjusting the Split Screen Ratio

Once two apps are side by side, both Windows and macOS allow you to drag the divider between them left or right to give one app more screen space than the other, useful when one window needs more room, like a spreadsheet, compared to a smaller reference window beside it.

Split screen is just one way to work more efficiently on your laptop. These guides can help you manage applications, share your display, and make sure your device is equipped for smooth multitasking.

Troubleshooting Split Screen Issues

Snap Layouts option not appearing on Windows: Go to Settings > System > Multitasking and confirm Snap windows is toggled on.
Split View not working on Mac: Make sure you are holding and dragging the green button rather than clicking it, a quick click only triggers regular full screen mode instead.
Apps feel cramped in split view on a smaller screen: If you frequently multitask, working across two physical displays instead of splitting one screen can make a noticeable difference. Our guide on connect two monitors explains how to set up a true dual screen workspace.

Final Thoughts
