I've made script using a few different whiptail boxes, which all work fine, but I'd like the font size to be larger. All my google searches on whiptail font size tell me either about whiptail box sizes, or about font sizes not related to whiptail. And nothing on the man page. Is there a way to change the whiptail font size?
No font options listed on the man page was a clue.
You just need to increase the font size on the terminal window in which the whiptail script is being run. Whiptail uses that font.
