This is really bugging me. The default font is 10 for Numbers and it's a little small. So I'm in the process of making/editing a spreadsheet for all the medical schools I'm applying to and I keep having to manually change the font to 12. I made a new blank template and just changed the font size (from Format --> Font) to 12, saved the template, and then opened a blank document from that template but it still is size 10. I'm confounded that it is this difficult to change the default font. But maybe I'm just missing something obvious?
