You are correct. DOS really has nothing to do with the font.

However, in DOS you can use tools to load a custom font. Many systems support 
running fonts that can range from 8x8 to 8x26 pixels. So, the number of lines 
of text can range from about 15 to 50. There is some stuff the BIOS can do to 
provide things like a 9x16 font. But those are really just playing games with a 
8x16 character.

Anyhow, you can use custom font tools to run the larger (or smaller) fonts. 
These will not change the size of the screen. They will just effect the height 
of the character and how many lines of text you get. That can be useful as well 
though.

If you install the extra package PGME (Program Manager Eternity) that is 
included on the 1.2 CD and Big USB image, you can easily play with bigger fonts 
in text mode. PGME is a dos menu system and program launcher. It has built in 
support for using custom fonts and one of its default menus includes viewing 
its documentation using a BIG (8x26) font. Included with PGME is the "Eternity 
Font Designer" to create and modify the type of fonts used by PGME. There are 
also command line utilities to convert to and from plain raster fonts (like 
those in the GNU Fonts package) to the format used by PGME. There are also 
tools to load the fonts from the command line or even turn them into 
stand-alone TSR programs.

That font being used is still a matter of your host environment, and as 
far as the number of lines is concerned, unless you play with VGA 
register level functions, it's 40x25,80x25 or 80x43 for an EGA 
compatible video adapter or 80x50 for a VGA adapter. You need to realize 
that DOS is plain text base, it just displays characters the way the 
video adapter does. And DOS does not have any direct functions to change 
that...

That's what I was wondering -- can you install a larger font to get 
larger characters, or will the window still be the same size so you just 
get less lines and characters per line?

You need to install VMWare tools in the guest to support resizing, and 
the tools are not available for DOS.

DOS doesn't know anything about a font nor it's size. If anything, this 
is something that needs to be adjusted in the virtual environment.
The only font related info is the character itself that is being 
displayed, depending on the code page, within the original 256 character 
extended ASCII set...

You want to scale the window resolution [0].  There are usually a few
options/techniques to choose from.  Look for scale or scaling.

[Freedos-user] Freedos 1.2 font with 4k monitor

[Gordon]

Is there an easy way to double the font size? When running Freedos in 
VMWare on a 4k monitor, the window is so small as to be almost unusable. 
None of the VMWare display settings change the resolution of the window. 
Even in full screen mode, the font size doesn't change.
