Iosevka is the king of scalable terminal/programming fonts. I'm not sure why, maybe it's because the glyphs have lines and angles that look "terminal-y" in the same pleasing way Terminus and the 3270 font do whilst avoiding the problems that accompany trying to scale a pixel font.

I love Iosevka. I use it as my monospace, serif and sans-serif fonts and it's gorgeous, in its own unique way.
