An expressive, unusual monospace typeface with ideal legibility, and character recognition, it aims to reduce eye strain when coding.

My thoughts on Intel One Mono

Designed by wonderful Frere-Jones Type, Intel One Mono is a quite unusual monospaced font. The typeface comes across as expressive. The four different weights make it suited for various situations, while the exaggerated, steeps italics truly stand out.

Intel One Mono was built with clarity, legibility, and the needs of developers in mind. The italics are quite steep so that they really stand out, which can be helpful in code formatting.

It is quite spacious and comes in four different weights: Light, Regular, Medium, Bold. You can use this to adjust the contrast for light and for dark backgrounds.
Regular on a dark background might be too fine, depending on the specific screen and rendering. Medium looks sturdier. So use it to adjust the contrast to the situation you use the typeface.

The goal of Intel One Mono is to reduce developer’s fatigue by enhancing legibility. The x-height is a bit decreased to better differentiate capital and lower case letters. The spacing is also quite generous. And to make every character as clear as possible, the typeface is sacrificing consistency over uniqueness, which results in some interesting details.

The e has very open apertures, the upper case I comes with wedge-shapes serif, while the 1 has a straight slab serif. The percentage sign has a disconnected diagonal stroke.
Some of my favorite details of Intel One Mono

At times this means making shapes simpler, like the extremely open e, but sometimes more complex and darker, like the dollar sign, the capital Q or the percentage sign. This results in a more diverse word shape, which makes the typeface accessible, also for people with a visual impairment.

With Intel One Mono, the characters are more unique and easier to differentiate compared to Roboto Mono.

Besides for code, I would only recommend using Intel One Mono for a little text. Set it in one size only, which this could be quite small, like between 12 and 16 px. If you bear that in mind, it can be the cool additional typeface for captions or marginalia that your design needs.

Recommended Font Pairing

Even though Intel One Mono has a lot of unique features, I’d categorize it as a quite dynamic linear sans-serif typeface. When pairing it with another typeface in one line, you should pay closer attention to the x-height, which is quite similar with the following suggestions. I’ll go into greater detail on this on Patreon in the Font Friday Video digest at the end of September.

  1. I know a coder whom I’m immediately sharing this post with. Other than that, I just came here to tell you that I’m grateful for that little l it’s so cute, little worm.🐛

    Other pairs that I like: rk and ra (in this order of letters).

    Oliver, have you covered Akkurat sometime before? I’d be interested to know.
