I'm using Microsoft Excel for Mac 2011 and by default, a new spreadsheet has a font size of 12 for cells. On a 4k screen resolution, font size 12 is a bit small, so I have selected the whole spreadsheet and updated every cell to now be font 16, however, whenever I paste a hyperlink, the font size on the cell becomes 12. Similarly, whenever I apply the preset format from the ribbon for Green background "Good" it also becomes font size 12.
How can I change the default font size for this spreadsheet to be 16? Similarly, is there a way to change the default for all new spreadsheets to be 12?
