Increase Mathematica's menu font size?

Hello, I have vision issues & need to increase the size of the font in my menu. Can someone tell me how to do this? Thanks, Jeffrey

Oh I am just seeing this. Are you still having issues. I am not sure which menus you are referring to, do you mean the File, Edit, … menus of the application? I guess those are rendered by your operating system using the same font sizes you would see in every other app. But if you are referring to some other menus, then please let me know and I will try to help

Well, if she is referring to the menus of the application like you suggested then I also have the same problem. In addition, how can I change the font sizes from the defaulted values in the FORMAT → STYLE menu?
