Distinctly IBM

As the new typeface for our diverse and global brand, Plex® is just as important as our name or our logo. It fine-tunes the tone of our words. It represents who we are and what we believe—as a company and as designers. Every decision was made with purpose; every detail has a reason for being.

IBM Plex Sans Italic: building characters with character.
We created Plex as part of a system, and as part of our identity. Just like the other elements of our brand; just like mankind and machine; Plex and IBM are better together.

We explored many iterations before landing on the right solution.

Eight bars, eight weights

Selectric Typewriter 1961: Plex’s engineered counter-forms reflect shapes that appear in some IBM classic designs, like the Selectric Typewriter. These forms are vital in making Plex unique.


IBM Plex Mono Italic: A little something for developers.

[↑] Selectric Typewriter, 1961: IBM brought interchangeable typefaces to the world at large. Before the “golf ball” there was pretty much one choice—“type bars” (which were also prone to jamming).

Monospace, not monotone

[↑] Each glyph in the entire Plex family has been TrueType hinted (i.e. optimized for on-screen legibility in small sizes).

IBM Plex Serif:
A hybrid of the third kind (combining the best of Plex, Bodoni, and Janson into a contemporary serif).

We thought the ball terminals of Bodoni Berthold were on-point.

We were also into Berthold Bodoni’s rectangular serifs.

We explored Plex Serif fitting into different serif classifications from Didone, Transitional and Scotch before landing on our hybrid version.<br><br><br><br>

Classic, not too classical.

IBM Plex Serif:
Always pointed, never oblique.

The Plex Italics were engineered according to specific angles that work best with pixels to get the smoothest on-screen rendering.
