Best fonts for apps - where to find and how to choose

Without a doubt, fonts are one of the most critical elements of UX . It can make or break the UI design. If your users are unable to read your content, you can say goodbye to them immediately. That’s why even a rudimentary understanding of typography means you can determine for yourself the best fonts for apps.

Legibility is everything and choosing the right font will have a big impact on the overall user experience of your mobile apps. In this post, we’ll look at how to choose fonts for app design. We’ve also thrown in a list of the best free and paid ones around!


Why your choice of fonts for apps is important

If words are what you read on the screen, then we can define fonts as the style of those words. Think of them as clothes for the words, their outfit if you like. Since each font is like a unique outfit, it stands to reason that each one will have a different purpose or intention.

Just like wearing a scarf in summer would be absurd, certain fonts work better in different situations. By creating a symbiosis between your UI design and fonts, you will be creating coherent user experiences.


Fonts fonts depend type and style of apps

Why do some fonts for apps work better than others?

Following on from our outfit analogy, let’s imagine you wear a Hawaiian shirt to a funeral. Seem appropriate? Neither would Comic Sans be on the menu of a Michelin-starred restaurant. In this way, many of us already understand the feeling that fonts can elicit. It’s this feeling that can help determine which are the best fonts for apps.

However, we’re not just talking about whether or not a font “goes with something”. Just because a font looks good doesn’t always mean that its appearance translates into other important areas: legibility, readability and usability.


Responsive fonts for better app legibility

Mobile is the dominant screen today so UX designers should ideally design with responsive typography in mind. Responsive typography have geometric and scalable outlines. Remember, fonts are there to be read, not for pretty decoration.


Another important aspect to improve readability and typography in your app is the spacing between your fonts. Check out our post on the best UX practices for line spacing to learn more!

If you have a font which displays large on an ordinary computer screen but doesn’t scale down properly when viewed on a mobile, then your website or  app wireframe is going to have terrible usability, even if you’ve chosen the best font in the world.


Responsive and fluid fonts improve legibility and readability

To really push the boat out, think about fluid typography. It’s like responsive typography’s more attractive cousin. Basically, fluid typography resizes fonts to match any screen not just at certain breakpoints as with responsive typography.


Arch-rivals; to serif or not to serif ?

Before we think about the best fonts for app designs, it’s important to make the distinction between two different styles. These styles are serif and sans-serif.


What a dashing font!

The Oxford Dictionary believes the word serif, to have originated from the 19th-century Deutch word “schreef”, meaning line or dash. With respect to fonts, a serif is a small line attached to the end of a stroke in a letter. Think of names like Times New Roman or Clarendon that everyone knows about.


That’s grotesque!

Conversely, a sans-serif – also known as Grotesque – is a font without serifs, hence “sans”. These fonts include familiar typefaces such as Helvetica, Proxima Nova and Open Sans. Many modern fonts for apps are sans-serif because they increase readability and can scale much more easily. They also tend to clash the least with most UI designs.


Serif and sans-serif are the two main distinctions

How to choose the best fonts for apps

The first thing you should do is disregard most fonts. It sounds drastic, but many fonts for apps that you can find on the internet don’t get widely used in mobile app design. However, every so often, a font will pop up and get used by everybody, like Gotham. Ubiquity isn’t something to shun when it comes to fonts, particularly if that font does the job well.

It’s likely that you can count on both hands the number of fonts that pop up frequently in mobile app design. The reason the same fonts keep showing up time after time in UI design is because they work best. They’ve been tried and tested again and again. They’re readable, legible and most people are familiar with them already. We’re looking at you, Proxima Nova!

Waxing technical

When picking out fonts for apps, these questions should help you distinguish a good font against a bad one:

  • How many weights does the font have?
  • Is readability good owing to the x-height?
  • Does this font scale well on multiple devices?
  • Is it accessible?
  • What’s the contrast ratio?

If a font has a wide selection of weight, a large x-height and scales well, then it’s likely to work well in most UI layouts, context permitting. Keep the general rules of usability and UI design principles in mind when picking the font.


Less is more

Whichever fonts you do decide on, limit yourself to using just one or two at a time. Sometimes just using one font at various weights can be just as effective as using multiple fonts.


Test, and then test some more

In the Justinmind UI design tool, you can use default and Google Fonts in your designs. They’re easily integrated into the tool. If you’re stuck between a few font choices then a great solution to this age-old problem is to simply prototype and test until you have the most appropriate solution. Some designers even go so far as to create a paper UI sketching of the design, already noting the fonts they feel would fit in.

Prototyping fonts can put you on the right track before making any commitments that might affect the UI design later on. As you work your way from a low-fidelity to a high-fidelity prototype, your style will never escape from your control.

Best fonts for apps – the takeaway

Asking what are the best fonts for apps is going to elicit a multitude of responses. The answer is, it depends. It depends on a range of different factors, from audience demographic and cultural context to device use and product objective.

Perhaps there is no “best” font for apps. Perhaps, it’s a question of what is the most appropriate given the pre-defined circumstances. And, frankly, isn’t that how all UI/UX design should be?
