How can I increase text size in Menu bar on MacBook Air?

In Ventura, if you run System Settings, then go into Accessibility, then go into Display, there is

Menu bar size (*) Default ( ) Large

control about halfway down the screen. If you change the setting, you must log out, and back in again, for it to take effect. I tried changing the setting, and didn't notice a huge difference in the size of the text – but there might have been some difference.

There are no separate settings to change that will affect only the Menu bar at the top of the screen.

Any changes you make to the screen resolution will affect everything on the monitor in one way or other.

If you wish, you can leave product feedback or submit a request for features consideration in macOS using this link: Product Feedback - Apple

You can adjust the Display System Settings and/or Accessibility System Settings:
