how can I increase the terminal text size on ubuntu server?

I am logged into an ubuntu server, the only monitor available is an old tv. The terminal text is very small, if I didn't know what it was saying, it would basically be illegible. In the terminal, (not the terminal emulator) how can I increase the text size?

I tried dpkg-reconfigure console-setup and changed the font to fixed, and the size to 8x18, the largest available, but it looks terrible, its even harder to read than whatever the default was.

Ubuntu server 18.04

In order to increase the text size you may decrease the console graphic resolution. https://linuxconfig.org/how-to-increase-tty-console-resolution-on-ubuntu-18-04-server should help.

It's probably a good idea to make sure you can ssh into your computer before trying some video modes. Just in case the changes make the screen completely unreadable.

AFAIR, the default font size is 9x16.
