Splitting Screen on Windows 10 is a Breeze! There is a keyboard shortcut + the usual mouse drag method — which can be beneficial on larger screen sizes. I’ll discuss both the techniques.
How to Split Screen on Windows 10 by Using the Keyboard Shortcut
As far as I know, this shortcut works quite easily if you want to split the screen vertically for two applications (side by side). Doing so will let the first application occupy 50% of the screen, and the second application the other half.
To get started on splitting your screen with the keyboard shortcut, follow the steps below:
- Choose the first application you want to use.
- Then, decide if you want to split it on the right side or the left side of your screen.
- Depending on the decision you make in the step above, open it, press the Windows key + left arrow (for left), or Windows Key + right arrow (for right).
- Finally, either the Operating System will let you pick the other application with a mouse click (likely not), OR, you’d have to manually split your second application by using the same shortcut, except, on the other side of your screen. For example, if you press Windows key + left arrow on your first application, on your second one, you’d press Windows Key + right arrow.
- Note that you’d have to bring your second application to focus first/click on it, before using the shortcut.

How to Split Screen on Windows 10 by Using Your Mouse
With this method, you’d be achieving the same result at the end of the day, you’d just be getting there differently. To take this course of action:
- Drag your first program/application of choice to either of the bottom or top corners. Doing so will generate a shadowy-outline, indicating the size your window will occupy after releasing your mouse. See the image below for reference.

- After you release your mouse in step 1, Windows will ask you which other application you’d want to split your screen with. (From all other open applications).
(See the image below for visual reference and context).

- Pick the one you want, and you’d be all set!

In Summation
Splitting Screen in Windows 10 can be quite advantageous if you’re a multitasker. In fact, on larger screen sizes, you can split your screen with up to 4 applications. Technically, it’s possible on smaller screen sizes too, if allowed, by dragging applications to the top corner first.
Whatever the situation is with your Operating system, act in a manner that best fits your need. And like many gems, I admire this feature in Windows 10 that’s geared towards simplicity, productivity, and convenient use of space.
