What do you do when you need a simple, versatile text typeface that everyone can use? Professional typefaces are often expensive and restrictively licensed,1, 2 Arial and Verdana look like 90's Microsoft Word. You can only Google Fonts in websites and Google docs (and Google is probably tracking you through them somehow, anyway). With a few exceptions, most other free fonts are either unattractive, limited, or don’t support enough languages.

For my day job as the graphic designer for 350.org, I make a lot of guides and templates for our volunteers around the world, but templates aren't very useful without typefaces to go with them — typography is a foundation of design.

Klima exists to fill that gap. Now in version 3.1.

Seven Weights

Six weights: Ultralight, Light, Regular, Medium, Bold, Heavy and Ultra

One typeface, seven weights. Light and regular are great for paragraphs and longer passages of text. Heavy is best at larger sizes, and Ultra is best in titles and headlines.

Language Support

Accents and Diacritics

Over one hundred Latin-alphabet languages supported, see below for the full list.



Handy for pointing at things. On Windows, press alt+24 for up, alt+25 for down, alt+26 for right, and alt+27 for left. On Mac, use Character Viewer. Or just copy and paste.

CO2 Subscripting


Do you know how many un-subscripted 2's a graphic designer at a climate change organisation has to look at? Never worry about an un-subscripted 2 in CO2 again (in applications that support OpenType).

What about commercial use?

Commercial use of Klima is not allowed under the license without prior written authorization.

Why? I don't want to undercut professional type designers. They do great work, and deserve to be paid for their labors! If you need a font for commercial use, try buying a professionally-designed one. You probably won't regret it. See the "alternatives" section below for recommendations.

With that said, there are always exceptions. If you'd like to use Klima for commercial purposes, email me at matthew@350.org and we can discuss it.
