RE: You know it is so much easier to change the font size on any browser and I wish there is an easy way for QBODT.

There actually is a way, and it's not hard.

Changing your display will change the font for everything.

If instead you want to change the default fonts for your reports, as you requested, do that by picking Edit | Preferences | Reports & Graphs | Company Preferences from the QB menu.

Then click the Format button and then, on the Report Format Preferences window that will appear, click on the Fonts & Numbers tab and change the font as desired for each category.
