On the downside though, a lack of italics for this font means that your text editor will attempt to slant the font to ugly results.

    Comes with Windows. Download for mac

    Consolas is specifically designed to work with ClearType, so may become highly aliased when ClearType is not turned on.

        Contributors:

          From Reddit user chrisdoner:

          Particularly advantageous apart from its aesthetic rounded/smooth appeal is that it somehow scales to tiny sizes while retaining legibility and under subpixel rendering.

            Anonymous Pro

              Contributors:

            Anonymous Pro (2009) is a family of four fixed-width fonts designed especially with coding in mind.

            Characters that could be mistaken for one another (O, 0, I, l, 1, etc.) have distinct shapes to make them easier to tell apart in the context of source code.

            While Anonymous Pro looks great on Macs, Windows and Linux PCs with antialiasing enabled, it also includes embedded bitmaps for specific pixel sizes (“ppems” in font nerd speak) for both the regular and bold weight.

              Envy Code R

                Contributors:

              This font offers well distinct programming characters like {} vs. () and the classically confusing 0O and 1lI. Quite narrow (like Anonymous Pro) but squarish, the letters are easy to read and offer a pleasing reading experience.

              The bold version has the same width than the normal version, which is useful for syntax highlighting.

              Envy Code R also fits more into a given width when compared to Source Code Pro. You can download it here

                DejaVu Sans Mono

                  Contributors:

                This nice open source font family is derived from the Bitstream Vera family, itself close to the Microsoft core Web fonts (see Andale Mono).

                The Sans Mono version is graphically close of Andale Mono, slightly bolder, with the added bonus of the bold font being of same width than the normal one (unlike Andale Mono). It is a nice property with some syntax highlighting text editors.
