Install `yay -S terminus-font` if not already done above.
Edit `/etc/vconsole.conf`, but depending on your output resolution you might want to have different sizes, e.g. `v16n` for `1080p`, `v22n` for `1440p` and `v32n` for 4K although `v22n` will mostly do for Full HD and WQHD.
```properties
KEYMAP=de-latin1-nodeadkeys
FONT=ter-v22n
```
To make it available early, add `consolefont` into your `HOOKS=(... consolefont)` of `/etc/mkinitcpio.conf`.
