I am on windows. In the R editor that comes with the R installation I can go to the "Edit" menu and thence to the "GUI preferences" at the bottom of the drop down. I get a pop up (that I cannot show) and there is a "Font" section that allows you to change font, and size, and style. Size options go up to 36 point font, but have many smaller options. The apply button at the bottom lets me see the results without closing the window.

On my Mac platform, it has menu entries in the "Format" menu that allow you to choose different fonts and sizes. On Windows, of course, the menus may be organized differently, but I would assume there's something similar. If you mean some other editor (e.g. see ?edit), then you need to dig into their docs. Again, I assume something similar would be available.
