Thanks for joining us here in the Community, tomevansii.

You've come to the right place for assistance. I'm happy to provide some info so you're able to change the font in your QuickBooks Desktop account.

While the option to enlarge the font is unavailable within QuickBooks, some users have had success by changing the Windows DPI and screen resolution. Here's how:

Solution 1: Change QuickBooks DPI settings
 

1. Right-click on the QuickBooks icon, then select Properties. 
2. Select the Compatibility tab, and select Disable display scaling on high DPI settings.
3. Click Apply, then OK. 
4. Open QuickBooks and check to see if the windows are visible. 
 

Solution 2: Change the Desktop View Preference

1. Open your company file.
2. From the Edit menu, select Preferences > Desktop View > My Preferences.
3. Switch View from Multiple Windows to One Window.

The following article offers additional info about fixing screen issues in QuickBooks Desktop.

Please give these steps a try and let me know how things look afterward. I'm only a comment or post away if you have any other questions.
