I wonder if there's a way to figure it out from this?
File > Options > General, the section 'When creating new workbooks' > Font size.
For the changes to take effect, restart Excel.
The next time you open Excel, everything will be big. However, if you open an existing Excel workbook that was created and saved in normal size, only the font of the formula bar will change.
Hi BD. I also read that. Unless I'm missing something (always a possibility) that is not the case for the Mac version. In fact, if I change the font size from "General, the section 'When creating new workbooks' > Font size", it changes the font for everything but the formula bar (on the 2016 Mac version). Formula bar text size stays the same no matter what I've done so far.
