The font size in QuickBooks Online (QBO) is set as default. However, we can make it easier for you to see the text and icons in QBO by maximizing your browser's screen size.
Here's how:
- Click the Ellipsis icon (…) on the upper-left corner of your screen.
- Zoom in the screen by clicking the Plus icon (+) on the Zoom option.
- Maximize the interface accordingly.
