Font size on the screen is much smaller on QuickBooks Online. Can this be changed?

A warm welcome to the Community, walt37081.
 

The font size in Quickbooks Online is set as default. Although, we can zoom in on your screen to maximize the size of your QuickBooks Online (QBO) interface.
 

Here's how you can do it:

1. Click the ellipsis icon ( ︙ ) on the upper-left corner of your screen.
2. Zoom in the text by pressing the Plus sign (+) beside the Zoom option.
3. Maximize the interface accordingly.

I also added an article as a guide to personalize your reports in QuickBooks Online: Customize reports in QuickBooks Online.

Feel free to reach out to the Community if you need more help in setting up your QBO preferences. Take care.
