A well-chosen font can simplify difficult technical material into a digestible form, therefore decreasing the workload and improving understanding. On the other hand, a poorly chosen typeface can cause discomfort for the eyes, hide meaning, and perhaps result in critical mistakes. The best font is not a one-size-fits-all fix but rather a strategic option that calls for careful thought of several elements, including the target audience, the goal of the document, and the particular information being expressed.

The article explores the subtle aspects of font selection in technical documentation and investigates the main ideas guiding font choice, common mistakes to avoid, and best practices to guarantee that technical papers are not only useful but also visually attractive and easily navigable. Technical creators can improve their works to unprecedented levels by knowing how fonts affect readability, correctness, and general user experience, therefore promoting clarity, comprehension, and finally, the effective spread of technical knowledge.

How to use fonts as a technical writer

Knowing the basic elements of a font helps one to choose fonts for technical papers with accuracy. Often subtle but powerful, these components greatly help a document to be aesthetically pleasing and generally readable.

Traditional and formal fonts are typified by serifs, like Times New Roman or Georgia, for printed products and long text due to their apparent elegance and simplicity of reading. Sans-serif typefaces, on the other hand, give a cleaner and more modern look even if they lack these artistic strokes. Common sans-serif fonts used extensively in digital documents and screen-based reading because of their clarity and legibility are Helvetica, Arial, and Verdana.

Especially in smaller font sizes, the x-height, meaning that height of lowercase letters excluding ascenders and descenders, plays a crucial part in readability. Greater x-height improves the visual weight of lowercase letters, therefore increasing their clarity. On digital devices, fonts having a higher x-height, Verdana or Calibri, can increase readability.

A font’s apparent strength and visual impact depend on its weight, that is, its stroke thickness. To highlight certain material, establish a visual organization, and direct the reader’s attention, employ diverse weights, regular, bold, and italic. Understanding these basic elements helps technical writers choose fonts that best maximize the readability and general efficacy of their writings.

Things to keep up in mind when choosing fonts for technical documents

A consistent font choice throughout the entire manuscript is most important. When there are too many distinct fonts, it might cause the readers to lose flow and make it harder for them to grasp. The correct distance between letters and words is another significant factor that contributes to the improvement of reading and the reduction of eye strain.

Accuracy is yet another factor that is vital. Selecting a font that can accommodate the required character set is crucial, particularly when the document contains mathematical symbols, code snippets, or characters from a foreign language. It is of the utmost importance to check that the typeface accurately generates symbols, subscripts, and superscripts, which are all considered special characters. 

Focus and clarity can be achieved by choosing the right font. Format headings and subheadings in distinct, easy-to-read fonts to establish a hierarchical structure. People frequently select sans-serif fonts for headlines due to their bold and modern appearance. Fixed-width fonts, such as Courier New or Consolas, are ideal for displaying code snippets and syntax highlighting. This is because they maintain consistent spacing and enhance the readability of the code. It is possible to emphasize specific ideas or keywords by using bold, italics, or underlining. 

It is imperative that technical documents are easily accessible. When it comes to readers who have visual difficulties, following the recommended font sizes is helpful. Larger font sizes are more readily available. The background and text color should contrast enough to make reading easier. Typically, people prefer the combination of dark text on a light backdrop or vice versa. Additionally, the choice of typeface, serif or sans-serif, can influence accessibility. Despite the fact that some studies suggest that serif fonts may be better readable for printed texts, it is possible that sans-serif fonts are more suitable for use on digital devices.

Errors to avoid when writing a technical document

Technical documentation often falls victim to the overuse of fonts. Using several fonts inside one document could visually clutter it and divert the reader from the information. Using a restricted number of fonts for headings, body text, code, and other sections keeps a uniform font palette.

Inconsistent font size is another frequent error. Different font sizes in body text and headings could upset the visual equilibrium and make reading difficult. Keeping constant font sizes guarantees a clean, professional look, particularly inside the same level of heading or text.

Another major error in technical documentation is ignoring branding rules, which can also compromise an organization’s professional reputation. Should your company have certain branding rules, you must follow them exactly in font choice. Fonts that fit the visual identity of the brand support the brand’s image and help preserve consistency.

Technical writers have the ability to generate articles that are not only precise and helpful but also visually beautiful and simple to navigate. Carefully selecting and utilizing fonts accomplishes this. If you follow these criteria, you will be able to guarantee that the technical documents you create are excellent instruments for communication and the transfer of information.

Helvetica

The Helvetica font is one of the most notorious fonts in the world. It is the creation of Eduard Hoffman, director of Haas Type Foundry in Switzerland and it first appeared in 1957. Its original name was Neue Haas Grotesk – a bit hard to remember, right? Shortly after its appearance, it became Helvetica, after the Latin denomination of Switzerland.

Originally, Helvetica was used for printing papers. But with no doubt this sans-serif font is doing very well in the digital era. Nowadays, lots of brands use Helvetica. To state some of its most famous usages:

• on the NASA spaceships, the name of the United States of America lays written in Helvetica;
• you can see Helvetica all over New York city because all subways signs are using that font.

This font is so cool it even has its movie. Released in 2007, Helvetica is a documentary film that gathers lots of opinions on typography in general and Helvetica in particular from many influential typographers and graphic designers. Check out the trailer here.

Georgia

Another very recognisable font is Georgia. Designed by Matthew Carter and Thomas Rickner, this serif font first appeared in 1996. At first, it was one of Microsoft’s core fonts for the world wide web, but after a while it became available on Macintosh too. Rumour has it that this font got his name after Georgia O’Keefe, the favourite artist of the Microsoft’s program manager.

Georgia was designed to go hand in hand with Verdana. Despite their different proportions – Georgia looks a bit smaller than Verdana when they are side by side at the same point size – they represent the perfect contrast pair. They are clear, readable and legible on screen, unlike other fonts that go well on print, such as Arial or Times New Roman.

Today, we all know about Georgia. It’s popular and goes well on text heavy sites. It’s pretty much the right choice for a more upmarket, classic design. But things were not always like this. Back in the day, Georgia was not that popular and it was perceived way too similar to Times New Roman.

Garamond

Old, but yet very recognisable. Garamond was created between 1530-1545 by a French type founder, publisher and type designer named Claude Garamond. This serif font is one of the typographical highlights of the 16th century. To create it, Claude Garamond found his inspiration in the handwriting of Angelo Vergecio, the librarian of the French King Francis I. It was brought back to life in the 1920s, by Stanley Morison and the Monotype Corporation.

There’s something very appealing about this font: the characters are fluid and consistent, while some of them have very unique traits. Just look at the small bowl of the lowercase ‘a’ or at the small eye of the lowercase ‘e’. These characteristics make Garamond one of the most easy to read fonts in the world.

Today, the one and only set of original Garamond type is in Plantin-Moretus Museum, Antwerp.

Didot

Created in 1784, the Didot font is as fresh today as when it first appeared. Member of the most recognisable fonts gang, Didot is the first font that unmistakably defined the modern style known as Didone.

Inspired a little bit by Baskerville due to its increased contrast and vertical stress, Didot has strong, clear forms and flat serifs. His neat and clean look make it more appropriate for fashion and cultural uses. Remember the new Zara logo? If not, check out the article on that here if you want to see this font in action.

Rockwell

Last but not least, let’s move our attention towards the Rockwell font. It’s a reinterpretation of an older font called Litho Antique and it was released in 1934. Made almost entirely out of straight lines, perfect circles and sharp angles, Rockwell is a simple serif font. Although the shapes are pretty complex, they don’t feel overwhelming at all. Also, because of its shape, it doesn’t read well when used in the body of a text. We recommend it mainly for the titles, it will surely be more effective.

When you think about Rockwell, you cannot help to not think about the architecture and design of Modernist movement. Simple, bold and captivating.

These are just some of the most recognisable fonts in the world. But, as we like to think, these are some of the most relevant fonts that everybody should have in mind when starting a creative project. Choosing a right font is as important as choosing an appropriate logo or catchphrase. If ever in need for a pinch of inspiration, check WhatFontIs.com.
