What is Snap in Windows?

Snap is a feature that was first introduced in Windows 7, which can also be found in Windows 8.1 and Windows 10. In Windows 7 and Windows 8.1, Snap allows users to arrange two windows side by side, each taking half of the screen. This can be especially helpful when comparing two documents or when moving files from one place to another.

In Windows 10, Snap can do the same thing as in previous versions of Windows but can also be used to snap four windows to the four corners of the screen (in a 2×2 grid), like in the screenshot below.

Since Windows splits the screen in a 2×2 grid, you can use it to snap three windows on the screen: two taking 25% of the screen and the third taking 50% of the screen , as shown in the screenshot below.

This is useful especially to people with large monitors and 4K resolutions that can easily work with more than two windows at the same time.

What is Snap Assist in Windows 10?

As the name implies, Snap Assist is a feature that assists users in snapping windows side by side. Once you snap a window to one side of the screen, Windows 10 displays a thumbnail list of your open windows. Click one of them and it will be snapped to the unfilled side of the screen.

It's faster and more intuitive than the Snap feature on Windows 7 and Windows 8.1. If you snapped a window in these operating systems, Windows displayed the empty space there and waited for you to snap a second window.

How to snap two windows side by side in Windows 10?

The fastest way to snap windows is to use keyboard shortcuts. Go to the window that you want to snap and then press Windows + Left arrow if you want to snap it to the left side of the screen or Windows + Right arrow if you want to snap it to the right side.

However, you can also use the mouse, like this: click and hold the title bar of the window that you want to pin to one side. With the left click mouse button still pressed, drag the window to the right or left side of the screen. You'll see a transparent overlay appear, showing where the window will be placed. Release your mouse button to snap the window there.

Snap Assist immediately shows up on the empty side of the screen.

Click the thumbnail of the other window that you want snapped to the remaining side of the screen and it will immediately be shown there. If you don't want to snap another window to the remaining side of the screen, click inside the window that you just snapped and you will see Desktop and the remaining windows, as they were arranged previously, in the other half of the screen.
