8 best monospace fonts for coding in 2021

So, why are monospace fonts good for coding? Well, these fonts allocate an equal space for each character, meaning a letter 'i' is given as much horizontal space as the letter 'k'. It may be unnatural and doesn't look right for other types of text and typography, but it's ideal for coding.

Reading numbers and punctuation marks is so much easier when they're evenly spaced. A monospace font makes it easier to achieve indentation and vertical alignment, which are critical for code legibility. 

We've picked the best monospace fonts designed for coding. While some are paid-for, others are free fonts, but with all choices special care has been taken to ensure punctuation is larger than usual, glyphs are distinguishable and they can be comfortably looked at all day. You can even customise some (or, alternatively, our guide to font design will help you to make your own). All of these has its own personality so your favourite will come down to your individual preferences.

01. MonoLisa

Designed specifically to improve developers' productivity and reduce fatigue, MonoLisa is a wonderfully clear font, which ensures all glyphs are the same width for readability but manages not to be boring. With a feature-set boasting increased character width, clear distinction and excellent reading flow, we think this is a winner.

02. Apercu Mono

Apercu Mono is part of the much larger Apercu font family. It was designed by The Entente and is part of the award-winning Colophon type foundry based in London (UK) and Los Angeles (US) that creates, publishes, and distributes high-quality typefaces for analogue and digital media.

The original concept behind Apercu was to create an amalgamation of classic realist typefaces such as Johnston, Gill Sans, Neuzeit and Franklin Gothic. The team created an extensive and usable family including a Mono version, ideal for displaying code.

The Mono version now includes four variations – Mono Light, Mono Regular, Mono Medium and Mono Bold. The standard font family includes upper and lower case, 72 accents and a couple of ligatures across all weights. The pro version adds in old style number glyphs, 100 symbols and more ligatures – more than enough for any coding aficionado. 

03. Fira Code

Fira Code is an extension of Fira Mono, a monospaced font designed for Mozilla to fit in with the character of Firefox OS. The code variant of Fira includes programming ligatures – these are special renderings of certain character combinations that are designed to make code easier to read and understand. So, for example, the == and != combinations are rendered as proper equality glyphs, which are supposedly easier for the brain to process than two separate characters that have their own individual meanings. 

How you feel about this of course depends on personal taste – if you’ve been reading normal code for years you might not want to make the change. But if this does appeal, Fira Code is a widely supported, popular programming font that makes code easy to read. It's also free and open source. The GitHub page has coding samples from a range of languages so you can see how things look.

04. Input Mono

Input is a system of fonts designed specifically for coding by David Jonathan Ross that comes in both proportional and monospaced variants. As it has been designed with coding in mind, the proportional spacing is tailored to that application so it may be that you will consider it over the monospaced version.

There’s a range of widths, weights and styles, each with serif, sans and monospaced variants, resulting in a total of 168 different styles. So you really can get exactly what you want with this font set. It is described as having generous spacing, large punctuation, and easily distinguishable characters, and the size and positioning of symbols frequently used in coding has been given great consideration. You can also customise the forms of certain key characters including the letters 'i', 'l', 'a' and 'g'. 

Input is free to use for private, unpublished usage in your personal coding app. If you want to publish text using something from the Input font family, you can see the prices here (from $5). 

05. Dank Mono

Dank Mono by Phil Plückthun, bills itself as being "designed for aesthetes with code and Retina displays in mind". Like Fira Code, it has the programming ligatures, and there’s also a cursive italic variant that’s useful for distinguishing different types of text within your code. Overall this font has been created for coders who have an eye for design, and the unusual lowercase 'f' is known for being particularly beloved among Dank fans. 

Dank supports the Western, Eastern, Central and Southern European Latin character sets, and you can use it within CodePen. 

To get Dank, you'll need to pay – a personal licence is £24 and a commercial one is £60. But if you’re a type connoisseur and you’re smitten with that jaunty 'f' it might be worth treating yourself to some Dankness. 

06. Gintronic

Creator Mark Frömberg describes Gintronic as "jovial" and "gentle", an antidote to what he sees as the overly technical and mechanical style of many programming fonts. Gintronic overall appears relaxed and easy to look at, with a few particular characters adding a special personality – check out the curly brackets, the question mark, the lower case ‘k’ and the numerals. Extra effort has been made to design glyphs that can be hard to tell apart – such as 'B' and '8', 'i'’ and 'l' and so on – in a way that makes them easy to distinguish at a glance. 

In total there are 1174 glyphs, so Gintronic has a massive character set that includes Latin, Cyrillic and Greek characters as well as a full range of mathematical and technical symbols. 

Gintronic is €50 for the single font, €100 for the Roman or Italic bundle and €150 for the complete family. 

07. Monoid

Andreas Larsen set out a list of priorities when he designed Monoid – he wanted it to be legible, compact (the more code you can fit on one screen, the better), and "pretty". To achieve these ends he compared three other programming fonts – Fira Mono, Source Code Pro and Pragmata Pro – and took note of features that he likes and doesn’t like from each to inform the design of Monoid. 

Like many programming fonts, Monoid has extra-large punctuation marks and operators; apertures are large to help make characters more distinguishable; and ascenders and descenders are kept short. Smart design decisions have been taken to make Monoid both compact and highly legible. It has programming ligatures, and there is also a special feature called Monoisome which enables you to see Font Awesome icons in your code.

Monoid is free and open source, so you can even tweak it to your tastes if you like. 

08. Hack

Over 1500 glyphs that you can customise (Image credit: sourcefoundy)

Among the fonts we’ve covered so far, there are some with huge character sets and several variants, so it’s likely you’ll find something that’s just right. But if you have very specific desires, Hack could be the one for you, as there’s a whole library of alternative glyphs made by users that you can add to if you like. Hack is therefore highly customisable – you can get right down into the detail of each glyph and edit it yourself if no one else has done it exactly as you want. 

Hack is free and open source. Head over to alt-hack, the alternative glyph library, to find out how to create your own custom version.
