- Product
- Word
- Device & OS
- not provided
- Scenario
- Comparing document content or transferring text and images between two separate files.
- Observed behavior
- The user wants to arrange open document windows side by side to facilitate multitasking without switching back and forth.
Ensure that both documents you wish to compare are downloaded to your local drive and fully opened in your word processor before attempting to arrange the windows.
Use the View Side by Side Feature
The most efficient way to compare two documents is using the built-in View Side by Side tool, which aligns them perfectly into vertical columns on your screen.
This feature is specifically designed for dual-document comparison. It automatically resizes your active windows so they share the screen equally.
Launch Microsoft Word and open the two documents you want to compare or edit.
Click on the 'View' tab located in the top ribbon menu of the Word application.
In the Window group, click on 'View Side by Side'. If you have more than two documents open, Word will prompt you to select the specific document you want to compare with the active one.
To scroll through both documents simultaneously, ensure the 'Synchronous Scrolling' button (located just below View Side by Side) is highlighted.

Use the Arrange All Option
If you need to view more than two documents simultaneously or prefer horizontal tiling, the Arrange All feature is the best choice.

Frequently Asked Questions
How do I turn off View Side by Side in Word?

Can I scroll through both Word documents at the same time?
Yes. Once you activate View Side by Side, the 'Synchronous Scrolling' feature is typically enabled by default. If it is not, go to the View tab and click 'Synchronous Scrolling' in the Window group so that both documents scroll together.
