For the last several weeks I've been using Comic Mono in my terminal. It's a fixed width typeface based on the font that we've all been trained to despise and sneer at for almost 30 years, Comic Sans.
But you know what? Comic Mono works really well at small sizes even with my becoming-elderly failing eyes and my inability to always find my reading glasses. I can see plenty of code in my editor with lots of context. On a 40" screen at arm's length I can comfortably get 100 lines of text - so lots of context for the code I'm working on - in a terminal using 12pt text and read it easily.
Give it a go for a few days!
