You can change the font and the font size. They are both defined in one line in the config file

~/.config/i3/.i3status.conf

I have been trying out other fonts on Archlinux, Antergos and Manjaro i3. You can always take a look at the coding and naming of the fonts here.

#font pango:DejaVu Sans Mono 12
#font pango:DejaVu Sans Mono, Terminus Bold Semi-Condensed 11
#font pango:Droid Sans Mono Dotted 12
#font pango:DroidSansMono 13
#font pango:Sans 13
#font pango:hermit 12
#font pango:Inconsolata 15
#font pango:monospace 12
#font pango:SourceCodePro-SemiBold 11
#font pango:Source Code Pro for Powerline, FontAwesome Regular, Icons 9
#font pango:Terminus 14px
#font pango:UbuntuMono-regular 12
