12 is right.
8 sucks.
Silly font sizes aside, there's some truly impressive miscommunication early on in this thread. Assuming neither of you were trolling it's amazing how you two complained about the size without saying what about the size was bothering you because each assumed it was so obvious it didn't need saying... eventually it lead to sarcasm and possibly some anger. Put it in verse and it could be the start of a Dr. Seuss book.
This is what you call small!
