If the console text is too small or large, you can change the default font and size.
If the /etc/default/console-setup.conf file is not present:
apt install console-setup
Find and change to the two lines in /etc/default/console-setup to:
FONTFACE="TERMINUS"
FONTSIZE="14x28"
For avaialbe fonts and font-sizes, see Reference [2].
Accordinbg to Reference [1], you can also use the systemd method and modify /etc/vconsole.conf. However, the referenced file, /etc/vconsole.conf, is not present in the Raspberry Pi OS or the minimum install of "Debian on the Raspberry Pi Hardware" [3].
I do not know how the font size in the minimum install of "Debian on Raspberry Pi hardware" [3] is handled. There is no /etc/default/console-setup file nor /etc/vconsole.conf file. However, it does a good job of selecting the font size. I need to investigate this further.
