How to split screen on Windows 10 and view apps side by side

The Windows 10 split screen feature is excellent for multitasking, especially if you’re using a large display. You can view apps in Windows 10 side by side, on top of each other, or both, since it’s possible to snap up to four app windows on the screen at the same time. And with Snap Assist, getting each window right where you want it is easier than ever. Here is how to split screen on Windows 10 and view apps side by side:

First thing first: About Snap and Snap Assist in Windows

Snap is the official name for the Windows split screen feature, and it has been around since Windows 7. In earlier Windows versions, Snap allowed users to arrange two windows side by side, each taking up half of the screen, which is especially helpful when comparing two documents or when moving files from one place to another.

In Windows 10, the split screen has been upgraded. You can now also snap three or four app windows on your screen (one for each corner), and you can accomplish this using either your mouse, keyboard, or finger (if you have a touch screen). This lets you compare or copy and paste data without the hassle of switching windows and losing track of what you were doing.

As the name implies, Snap Assist is a feature that assists users in snapping windows side by side. If enabled, once you snap a window into place, Snap Assist lets you choose between your other open windows for the one you want to fit on the remainder of the screen.

Some apps cannot be used in split screen mode at all. Others, like the Photos app, can only be minimized to a certain extent while still being useful. Therefore, depending on your display, they might not resize automatically as you’d expect when snapping them to take up a quarter of your screen.

Enable Split screen (Snap) and related settings like Snap Assist in Windows 10

The Windows 10 split screen and its related settings should be enabled by default, but you can always make sure they are turned on. Open the Settings app by simultaneously pressing Win + I on your keyboard, and access System.

Access System from Windows 10 Settings

On the left-hand side, scroll if you need to, and access the Multitasking tab. The split screen settings are displayed on the right-hand side. To use Snap and Snap Assist efficiently, all the options in the “Work with multiple windows” section should be enabled. Make sure the Snap windows switch is On, and the three boxes underneath are checked.

How to view two applications side by side in Windows 10

The fastest way to use split screen and snap app windows is with keyboard shortcuts. Go to one of the windows you want to snap and press the Win + Left arrow keys simultaneously, to snap it to the left side of the screen, or Win + Right arrow to move it to the right half. If you prefer using the mouse or your touch screen to snap, click or press on the title bar of a window to grab it and drag it to the left or right edge of the screen. A transparent overlay appears, showing a preview of the window’s placement. Release the mouse button or take the finger off the screen to snap the window into the indicated space.

Whether you’re using your mouse or your keyboard, Snap Assist shows up on the empty half of the screen as soon as the first window is into place. Click or tap on the window you want to take up the other half of your screen. You can also use the arrow keys to move between the shown window previews and press Enter to choose the one you want taking up the remainder of the screen.

Click or tap on an app to snap it to the left side of the screen

To exit Snap Assist without snapping a second app window, press the Esc key (or click or tap anywhere else on the screen). The snapped app window stays in place, and the other windows return to their initial position. Use the mouse or the keyboard shortcut corresponding to the free half of your screen if you want to snap a second window manually later on.

NOTE: You can easily resize the two side-by-side windows by clicking (or tapping on a touch screen, but it takes a few tries) on the dark divider line between them and dragging it to either side of the screen. Since they are snapped together, the windows resize simultaneously.

Hovering your cursor over the edge between the app windows highlights the divider line and makes it easier to click.

How to snap windows to the four corners of the screen using the keyboard in Windows 10

If you have a large display and you need to access more than two windows, you can use Corner Snap to fit three or four windows on your screen at the same time. If you prefer keyboard shortcuts, it’s easiest to first split your screen into two halves, as seen in the previous section, before using Corner Snap. Select one of the two windows snapped into place and use the keyboard shortcut Win + Up arrow, to move it to the upper corner of its half of the screen, or Win + Down arrow to reposition it in the lower corner.

As soon as the window is moved, Snap Assist pops up, asking you to select one of the other open windows to fill the empty part of your screen. Use the arrows to navigate between the previews and press Enter to select a third window to display on your screen.

Select the third window to snap

Your screen is now split between three windows.

To show four apps, you can select the window that takes up half of your screen and repeat the process. First, press Win + Up arrow or Win + Down arrow to snap the window to one of the remaining corners, and then use Snap Assist to select another window for the empty corner showing the previews.

Choose a window for the remaining corner

You now have four app windows displayed on your screen at the same time.

You screen is split between four windows

If you want to start setting up your split screen corner windows from scratch, and you want to do it using keyboard shortcuts, the process is a bit more complicated. Select a window and use Win + Right/Left arrow to first move it to a side of the screen. Then, without releasing the Windows key, use Win + Up/Down arrow to move it to the desired corner. Releasing the Windows key before the app is in a corner makes Snap Assist pop up, and your screen just gets split in half. If this happens, press Esc to exit Snap Assist, and continue with the second keyboard shortcut.

Snap a window to the corner

Once one corner is full, open another app window and use the same shortcuts to snap it into another corner. If you snap the first two windows on top of each other, Snap Assist pops up to fill the other half. But you can place them in opposite corners to avoid it. Keep in mind that Snap Assist appears only when there is no doubt over which part of your screen needs filling up.

Placing windows in opposite corners avoids Snap Assist

You can use the same method to snap a third window into place. Snap Assist can no longer be avoided in this case and eagerly shows up to help with the remaining corner. Choose a fourth window to snap, and you are done.

How to snap windows to the four corners using the mouse in Windows 10

When it comes to fitting app windows into a quarter of the screen, the mouse is the best way to do it. Press the app’s title bar to grab it and drag it to one of the four corners of your screen to make the transparent overlay appear. Release the mouse button when you are happy with the placement preview.

The transparent overlay shows the corner for your window

You can then open another window you want to use and do the same. The Snap Assist pops up to help you when either the left or right half are free or when or a quarter of the screen remains empty. If you have a touch screen, you can also use your finger to drag and drop apps to the corner of the screen with this method. However, it might take several tries, because the overlay doesn’t always show up when it comes to Corner Snap.

How many apps do you use with split screen in Windows 10?

We like the split screen feature in Windows 10, but we generally use it with two windows only. Adding more apps makes them too small on our monitors, and we end up wasting time trying to find the info we need. What about you? Is your monitor big enough to fit four app windows on it?
