Linux

U001 is my main system font as a clone of Univers. Monospace is Berkeley Mono—it might be paid/proprietary but boy does it look nice & was an upgrade from several years with Iosevka. JuliaMono is its fallback though since I use Unicode with frequency & Berkeley doesn’t cover all the symbols I use.

The important part is if you care anything about your fonts, you won’t destroy them by patching in that uncurated hodgepodge called “Nerd Fonts” clobbering used symbols or the wrought-with-false-positive “coding ligatures” which is not how ligatures are supposed to be used but programmers refuse to demand Unicode support in their languages to fix the problem.

I always end up with SF Pro Display for my desktop. For terminal I’m happy with several mentioned here.

Gohu Font Nerd is a nice small bitmap font I'm fond of. Only issue is the size for high DPI monitors, but the JetBrainsMono nerd font is a nice vector font that's easy on the eyes (quite stereotypical/cliché, but that's for a reason).

I like Maple Mono https://github.com/subframe7536/maple-font

any with a dotted zero, extra points for italic.

I know that this will anger some people, but I just use the defaults and I don't get why there are so many fonts, since they don't seem that much different to me.

Anyone using Nimbus Sans?

It's actually preinstalled in a lot of systems. You can check via
gnome-font-viewer or find /usr/share/fonts -name "*Nimbus*"

I don’t have a reason to move away from the Fedora defaults except for monospaced fonts.

Terminal wise, terminus is my default. It’s so clean, and it looks good without anti-aliasing.

Roboto Mono is my current preference for monospaced fonts.

Adobe Source Code Pro and JetBrains Mono are good alternatives as well.

I like Delugia for any monospace needs. It's a nerdfont, and it's nicely readable without looking too chunky.

Ubuntu Mono for terminal, code, and data, Open Sans for the rest

Code new roman! It's so cosy, and readable. I am a suckered for fonts with the cursive styled 'a'

i want serifs. I use Go Mono for monospaced text. i've yet to find a good proportional slab serif font to match though.

I love Eurostile Regular. Git it at https://freefonts.co/fonts/eurostile-regular

Whatever comes default with the current system.

I don't have a favorite system font, am I meant to? I did try to play with fonts at one point but the process of finding fonts and then figuring out how to install them was a bit much.

I love Cartograph CF for the terminal and code editor. I like the handwriting-style italic variant, and it has programming ligatures. And of course I like the way the font looks.

There is an open-source font, Victor Mono, that also has a handwriting-style italic variant and programming ligatures. Otherwise its style is quite different.

I switched to Commit Mono for Terminal not too long ago but I really like it. Otherwise I use Cantarell but only because it is default and I never felt the need to change it.

@SolarPunker I use Exo2 as desktop font and FantasqueSansMono in terminal.

I mostly use an android, and the default font is Ideal Sans Light. On my system, Arial Nova, Courier Prime, Helvetica Neue, Ideal Sans Book and a few others are regulars.

Every once in a while I get this itch which ends up in getting a new favourite font.

Verdana, Tahoma and Source code pro is good for eyes
