font follows function

As software developers, we always strive for better tools but rarely consider font as such. Yet we spend most of our days looking at screens reading and writing code. Using a wrong font can negatively impact our productivity and lead to bugs. MonoLisa was designed by professionals to improve developers’ productivity and reduce fatigue.

Designing a monospace font is much harder than a traditional, proportional one: being constrained by the same width of all glyphs can result in a boring or unreadable font.

MonoLisa features a few unique techniques that increase the legibility and make it visually pleasant to look at for longer periods of time.

Increased width

Increased character width helped us designing a typeface with more natural, open forms. The shapes are more relaxed creating less eye strain over long periods of time.


MonoLisa is ~7% wider compared to other monospaced fonts.


Distinction is critical for a good coding font since it reduces ambiguity and helps avoid mistakes that can lead to software bugs.

MonoLisa has a set of glyphs that fit together but at the same time are distinct enough so you can tell them apart.

Different terminals of capitals
Similar characters look different
Zero, capital O and Ø


Monospaced fonts tend to have unevenly distributed dark and light space when compared to regular typefaces. MonoLisa carefully compensates the issue by using unique letter shapes to maintain the balance.

Reading Flow

MonoLisa uses open forms and terminals (starting and ending points) that are pointing towards the neighboring letters to let the eye follow the line of text fluently.



The italics of MonoLisa are not simply slanted versions of the upright font. Some clearly differently constructed glyphs make the difference.



If simple italics are not enough, there is a script version available.

The quick brown fox jumps over the lazy dog and runs away.

Coding Ligatures

MonoLisa comes with over 120 specially designed coding ligatures. Ligature is a special symbol that combines two or more characters together so it looks like one token. Ligatures help reduce visual noise and balance white space by aligning special symbols appropriately.



MonoLisa was designed with developers in mind. It’s one of the few fonts that comes packed with symbols to use in CLIs including PowerLine.


OpenType Features

MonoLisa includes many OpenType features to enable great customization for the most demanding aesthetes.

What Developers Say

As a consultant, an instructor, and a presenter, having a clean and engaging mono font is paramount, and MonoLisa delivers information perfectly to everyone without forgetting to sneak in some personality in a gentle smile.

MonoLisa is now my go to font for all places. It has become my expectation in my terminal and code to the point that seeing other fonts confuses me. From the well designed and unique characters make it simple to parse and read throughout the day.

This font is so sharp that the readability of my code increased a lot! Definitely a font I will use for a long time.

I love it ♥️

I’ve been using MonoLisa as my editor font for the past few months. After a small adjustment period, I really grew to love it. Going back to any of my old font choices feels like a downgrade in comparison.

I’ve been using this font for months, and while the slightly wider nature of this font took a little getting used to at first, it eventually grew on me and I saw how well this font works with my daily workflow. A great, quality font and I highly recommend it!

As someone with an eye condition this font makes my life way easier. And not just in coding but even in design since it doesn’t only carry regular but the whole set of weights so you can even use it in design, logos or anything a monospace font makes sense.

I switched to MonoLisa after trying out several different fonts in my terminal and in my IDE. As a coding instructor and speaker (and just someone who codes a lot in her free time), readability is always the most important thing to me in a font.

I’m not much of a font guy, but after using this font for just a few days it’s grown on my and I really like it. (And people wasted no time in constantly asking me what font I use). Two thumbs up 👍👍

I had been struggling with some vision issues before and MonoLisa really helped me a lot by taking a lot of strain off my eyes.

MonoLisa is the perfect coding font IMO. Spacious, stylish, and super readable. I never pictured myself having such strong feelings about a font, yet here we are.
