Recognizing this critical need, a dedicated effort was launched to craft Google Sans Code, a monospaced typeface specifically designed to make code more readable. This involved thorough research into the 20 most common programming languages and how developers interact with code, aiming to make the new coding typeface more visually appealing while reducing the ambiguity of similar-looking letterforms. Based on these insights, Google tasked the Universal Thirst foundry to meticulously focus on specific letters, numbers, and operators to meet these requirements. The result is an eminently readable and surprisingly playful typeface.

Google Sans Code launched as an open-source font in 2025, and is the typeface used to display code in Gemini.

While there are some really great coding and monospaced fonts out there in the world, Google Sans Code is my personal favorite. You will also find that code in this blog will be typeset to it as well.

Some examples here:

I also changed the body font to be Bricolage Grotesque and the blockquote to prefer Iowan Old Style with fallback to Newsreader.

Mac system fonts should still contain Iowan Old Style but it looks like it might be on its way out. While I can appreciate New York, it just doesn’t have the presence of Iowan Old Style.
