To double the font size: `setfont -d`.

To revert to the default font: `setfont`.

From the manual page:

```
-d     Doubles the size of the font, by replicating all of its pixels
       vertically and horizontally.  This is suitable for high pixel
       density (e.g. "4k") displays on which the standard fonts are too
       small to be easily legible.  Due to kernel limitations, this is
       suitable only for 16x16 or smaller fonts.
```

One could also set up aliases with available fonts from
`/usr/share/consolefonts/*psfu*`, such as

    alias f1='setfont lat9w-14'
    alias f2='setfont lat9w-16'
    alias f3='setfont sun12x22'
    alias f4='setfont solar24x32'

but of course this is not much handy on a different machine, an
installation media or a rescue shell.
