As I’m sure you know, programming involves spending hours staring at code. This can lead to eye strain, yet many developers don’t think to change their coding font.
Have you noticed that your eyes start to blur after going through hundreds and hundreds of lines of code? Or perhaps you end up with a headache after a day of programming? If so, it might be time you switched to a different font.
For example, Crocoblock developers, who spend hours inside code editors building JetPlugins, know from their own experience how much of a difference the right programming font makes. In this article, I will share the best programming fonts for developers sourced from my own research and knowledge shared by developers.
Why Switch to a Different Coding Font?
Developer environments and tools don’t always use the best font for coding in WordPress. Although some programmers are fine with their chosen tool’s default font, others can struggle with poor readability and eyestrain.
Although many programming tools allow you to change the font, not all developers think to do this. You might not realize you were using a subpar font until you change over to a better one.
Once you switch to a good font, you will likely notice fewer headaches, less eyestrain, and an improvement in your workflow.
Here are some things to look out for in the best programming font for long coding sessions:
- Character distinction — the characters should be clear and easy to read. There should be a clear difference between the letter “O” and zero, as well as the number 1, lowercase “L”, and uppercase “I”.
- Ligatures — special character combinations that are visually rendered as a single symbol while the underlying code remains unchanged. There are multiple variations of how to display certain characters, so you are able to customize it to your preference.
- Readability — the programming font should be readable and clear during long coding sessions.
What Is a Monospaced Font?
Many programmers prefer monospaced fonts, so I should probably take a moment to explain what those are. Monospaced fonts are those where all or most characters take up the same amount of horizontal space.
You may notice that monospaced fonts tend to add some stylistic touches to some of the characters to make them fit neatly within the same amount of space as all the other characters. For example, the lowercase “i” will often have serifs at the top and bottom to widen it, and the letter “m” will be squashed to fit in.
The reason why monospaced fonts are so popular for programming is that individual characters are vitally important. One incorrect character can mess up your entire code, so it’s important that you can see every character clearly.
Compare this with regular text, where individual letters are not so important as it’s more about the overall meaning of the words and sentences. Thus, monospaced fonts are less common outside of programming.
6 Best Coding Fonts Compared
So, programmers tend to prefer monospaced fonts. But that doesn’t mean any monospaced font will do. Each font is a bit different, so it’s worth looking for one that works well for you.
If you want to explore a wide range of coding fonts and compare them, check out CodingFont. They have 30 different coding fonts you can quickly switch between to see what they look like.
But if you just want a handful of awesome programming fonts to try, below are six of the best I have found.
Here is a quick takeaway from the comparison of the selected fonts:
| Font | Free/Paid | Ligatures | Best For |
| Fira Code | Free | ✅ | Dynamic WordPress projects, PHP templates, and JavaScript-heavy workflows |
| Consolas | Included with Windows | ❌ | Traditional coding environments and developers who prefer standard character rendering |
| Input | Paid | Optional | Front-end development, CSS/SCSS, and custom design workflows |
| DejaVu Sans Mono | Free | ❌ | Linux development, server administration, and terminal-based tasks |
| JetBrains Mono | Free | ✅ | WordPress plugin development, debugging, hooks, and query optimization |
| MonoLisa | Paid | ✅ | Professional development teams and long coding sessions involving large codebases |
Fira Code (Free)
🏆 Best of programming fonts with ligatures.
Fira Code is a monospaced coding font with ligatures, which is a very helpful feature. This combines commonly used multi-symbol sequences into single characters, making it quicker for you to scan through it to find specific bits of code.
For example:
- Using – and > together results in one arrow symbol.
- Typing <=> results in one two-way arrow symbol.
- Typing \ and / together results in a downward arrow.
This doesn’t actually change the individual characters themselves. It just changes how they are displayed, so they are quicker and easier to read.
In addition to this, you can also fine-tune how the font is displayed to suit your particular preferences.
Consolas (Free)
🏆 Best for familiar, distraction-free coding.
If this font seems familiar, your eyes are not deceiving you. Since Windows 8 was introduced in 2012, it has been the default font in Notepad.
I must confess, when I was younger, I used to wonder why Notepad used this typewriter-style font that differed from the fonts used in other text editors, such as Microsoft Word. Now, in hindsight, it seems obvious that this is because many programmers use Notepad to edit their code.
However, Consolas has proportions closer to normal text than traditional monospaced fonts like Courier, enabling a more comfortable experience when reading through lots of text.
Input (Premium)
🏆 Best for personalized coding environments.
If you like customizing things to suit you, you might want to check out Input. Rather than being one single font, it is a flexible system of fonts intended for programmers. For example, you can choose between monospaced and proportional fonts and decide on your preferred width, weight, and style.
Adding up all the variations available, Input offers as many as 168 individual styles. For some people, this might feel like they are spoilt for choice. But others will welcome the opportunity to fine-tune their programming font so that it suits them perfectly.
DejaVu Sans Mono (Free)
🏆 Best for open-source and Linux development.
The intention behind the DejaVu fonts was to cover the whole Unicode character set entirely. Unfortunately, they didn’t quite achieve that, although they do provide greater character coverage than many other fonts.
DejaVu Sans Mono is no exception to this, but is specifically intended for programmers due to its readability and distinguished characters. Due to its free, open-source nature, DejaVu Sans Mono comes bundled with many operating systems, including Linux. So, if you already have this font on your computer or laptop for programming, you might want to try it before you go to the bother of installing another one.
JetBrains Mono (Free)
🏆 Best for WordPress plugin and backend development.
If you use a JetBrains development tool, you may already be familiar with the JetBrains Mono font.
Similar to Fira Code, it comes with many space-saving ligatures. 139 of them, in fact. It also has 8 different weights and is available in 145 languages.
But one feature I particularly like about JetBrains Mono is its increased letter height. Although characters are standard width, lowercase letters are taller. This significantly reduces the length of your lines of code.
Also, oval shapes are slightly more rectangular in appearance, which makes the whole pattern of the text more clear-cut.
MonoLisa (Premium)
🏆 Best for professional developers and extended coding sessions.
If you are not concerned with the length of your lines of code and prefer a wider font, you should check out MonoLisa. It is about 7% wider than most other monospaced fonts.
However, unlike the other fonts on this list, MonoLisa is not free, starting at $59.50 for the Basic version. So, before deciding whether to buy, you might want to take a look at the character set and font playground.
In the font playground, you can see how the code looks for various types of code, such as JavaScript, CSS, and PHP. You can also switch the ligatures on and off to see what the code looks like with and without them.
Fonts Crocoblock Developers Actually Use
Choosing the right font for programming depends mostly on individual taste, but specific features become more significant when handling extensive code repositories, debugging complex logic, and maintaining WordPress plugins used on thousands of websites.
The Crocoblock developers work on JetPlugins daily, which makes a solid ground for recommending a particular font (or not). While there is no single font used across the entire team, some options consistently stand out because they enhance clarity, reduce eye strain, and make frequently used symbols easier to distinguish.
For JetEngine development
JetEngine development involves work with PHP, JavaScript, SQL queries, dynamic listings, custom relations, and template logic. When working with complex query builders or debugging dynamic content structures, readability becomes especially important.
Many developers prefer JetBrains Mono and Fira Code for this type of work. Their clear punctuation and optional ligatures make operators, brackets, and template syntax easier to read through, which can be helpful when reviewing large blocks of code or troubleshooting dynamic functionality.
For JetFormBuilder development
Developing advanced forms often requires switching between PHP and JavaScript while working with validation rules, conditional logic, calculations, and custom actions.
To ensure clarity in diverse coding environments, fonts like JetBrains Mono and Fira Code are used, whereas programmers leaning toward a traditional appearance often select Consolas. The main benefit is the ability to easily differentiate between similar-looking characters while inspecting logic, variables, and validation rules.
For JetSmartFilters and query optimization
Performance-related development frequently involves debugging database queries, reviewing REST API responses, and optimizing filtering logic.
In these contexts, developers usually prefer fonts with distinguishable characters and well-defined spacing. Highly readable typography helps with identifying code errors and understanding elaborate query patterns during SQL analysis or parameter tracing, preventing needless visual strain.
Front-end work with JetThemeCore and JetMenu
Front-end development introduces another set of requirements. Working with JavaScript, SCSS, HTML templates, and dynamic layouts often means navigating large files and switching between multiple languages throughout the day.
Some coders value Input and MonoLisa for their adjustable features and pleasant spacing, though many still lean toward the well-known JetBrains Mono. Selecting the ideal typeface typically depends on individual taste and the extent of front-end development required.
FAQ
There is no single best programming font for WordPress developers, but JetBrains Mono and Fira Code are among the most popular choices. Their readability, clear character distinction, and support for ligatures make them well-suited for PHP, JavaScript, custom plugins, and dynamic WordPress projects.
Ligature fonts can improve readability by displaying common character combinations such as `!=`, `===`, `->`, and `=>` as unified symbols. Many developers find this makes code easier to scan, although some prefer traditional fonts without ligatures. At Crocoblock, both approaches are used depending on personal preference and project requirements.
They commonly prefer fonts such as JetBrains Mono, Fira Code, and Consolas. These fonts make it easier to work with hooks, queries, conditional logic, and dynamic content structures that appear frequently in WordPress development workflows.
