Open Sans is a clean humanist sans serif typeface designed by Steve Matteson (Type Director of Ascender Corp). Open Sans was designed with optimization for UI, web, and mobile in mind. What makes this font great for UI is the way it was designed using upright stresses and open forms, which makes it easily readable, enhancing readability. Another upside of using this font for your UI project is it comes with a complete 879 character set, including ISO Latin 1, Greek, and Cyrillic.

Roboto is another Google font that is excellent for UI design. It features a seamless mix of geometric forms, with open curves. This makes Roboto flexible for many purposes. Especially in web and mobile, where readability at different point sizes is paramount. One of my favorite aspects of choosing Roboto for UI is that there are three families of Roboto: Regular, Condensed, and Slab. This allows you to mix and match for all use cases.

Why Is Typography Important In UI Design

As the digital age evolves, more people interact with UI every day. As a result User Experience Design (UX), User Interface Design (UI), and the technologies they are built on are becoming more and more important. Anyone developing a User Interface needs to make sure the experience is intuitive, effortless, and easy to use. This is why choosing fonts for UI can make or break the user experience.

When choosing fonts for UI, it is not all about what feels on-brand. Effective UI Design marries function and form. So how do you choose the right font for UI?

Here are some practical guidelines for choosing fonts for UI.

How To Choose The Best Fonts For UI

Readability & Legibility

You want to look at the context of what the font is being used for, and ask yourself; is it going its job? For example, body copy needs to be easy to read. Headers or display fonts are usually meant to draw attention, while also being readable. As much as clients might want a more unique font from time-to-time, the deciding factor should always be readability and overall usability. For example, below is simply the worst font you could choose for body copy.

Easily Distinguishable Letters:

Best Fonts For UI Design - Hard To Read Fonts

While some fonts can be aesthetically pleasing and have visually consistent letterforms, this can have a negative impact on readability. Especially when viewing fonts at a small scale in user interfaces. You want distinguishable differences in letterforms to aid scanning.

When choosing the best for UI, look for the following letters in combination to ensure there’s enough difference.

Lower case A, C, E, O: (a c e o)

Capital I, lower case L, and the number 1: (I l 1)

Lower case descenders: (y j p q)

Easilly Distinguishable letter-forms

Having clear visual differences between capital I, lower case L, and the number 1 is a good initial test when assessing UI font readability.

Ample X-Height:

Good UI Font Characteristics - X-Height

X-height, in typography, measures the vertical space between the baseline, and height on lower case letters (ignore capital E and ascenders like the top of h).

It is important to look at the x-height because this area houses the most recognizable part of letters. You should always stress test potential font options be mocking them up as the smallest scale. Look for fonts with good-sized x-heights, as you will notice they are usually more readable.

Pick A Robust Font Family

Font Family Flexibility - UI Design Fonts

How many weights does it have? This is an important question, as incorporating 2 or 3 weights can help create hierarchy and emphasis. If the font family has four or more weights, this is a good sign. Furthermore, if the font has a condensed version, this is great for display headers or other branding opportunities outside of UI. Overall, the more weights and versions, the more flexible the font will be for your project.

Google Fonts vs TypeKit – How Do They Compare?

What Google Fonts and Adobe TypeKit have in common is, they are both web font services. These two services deliver fonts from their servers to browsers and websites around the world.

Google Fonts:


Google Fonts are often preferred by web and mobile designers because they are open-source and free to use. Not to mention they are easy to download and integrate into websites. It’s important to note, a lot of the Google Fonts were designed specifically for web design with site speed in mind. Google Fonts are free for personal and commercial use.

Adobe Typekit:


In contrast, Adobe TypeKit is a font service that comes with an Adobe Creative Cloud subscription. This Adobe CC subscription is rather pricey, at roughly $50 per month. Graphic Designers sometimes prefer TypeKit, because of the high quality and large variety of fonts. TypeKit Fonts are free for personal and commercial use, as long as you have an active Creative Cloud subscription.

What both of these services have in common is, you have to rely on their servers to deliver the fonts. This means page load times will increase slightly.


If you made it this far, I hope you have a good idea of what fonts are best for UI Design. In Addition, I hope you learned what makes a font good for UI purposes. Any of the fonts we recommend are great choices. That said, I know there are even more fonts we didn’t cover, which are solid options for User Interface Design.
