Cell Typography Suggestions and Pointers

Typography considerably impacts how customers understand a model and work together with its cell apps. Good typographic decisions guarantee legibility, set up a transparent visible hierarchy, and categorical model id.

Whereas each app designer has their very own model and method to typography, designers can guarantee their cell app textual content is efficient by making use of basic design rules, understanding consumer expectations, and evolving with cell know-how and tendencies.

As a UI/UX designer with in depth expertise in mobile-first design, I perceive the significance of utilizing the precise font kinds, sizes, and preparations to create visible concord on smaller screens. Listed below are 5 tips for designing sensible and interesting cell typography, together with selecting an appropriate typeface on your app and making your design accessible to all customers.

Give attention to Readability

When selecting a typeface on your cell app, your major concern needs to be readability, which is important for content material consumption, accessibility, navigation, model consistency, and lowering consumer errors. Whereas readability performs an vital position within the consumer expertise of all digital merchandise, it’s paramount in cell apps, the place restricted house and diminished consumer consideration spans make fast and clear communication key.

In my work for the meals supply app NOM NOM I prioritized clear typography and legible fonts throughout the app to verify customers may simply learn menu merchandise descriptions, costs, and allergy info. I additionally optimized the readability of navigation parts together with classes, filters, and buttons, serving to customers to easily discover the app and efficiently place an order.

When evaluating fonts for cell typography, take these elements into consideration:

Serif vs. Sans-serif Fonts

Of the 5 typeface classes, cell designers sometimes select serif or sans-serif fonts for his or her apps. Each have distinct traits that may impression an app’s aesthetics and readability.

Serif fonts make it simple to differentiate between sure characters (capital “I” versus lowercase “l” versus the quantity “1,” for instance). Whereas these fonts was once principally related to printed supplies, advances in display screen decision imply that they’re more and more utilized in digital merchandise resembling cell apps.

Georgia is an elegant and legible serif font that’s utilized by respected establishments resembling The New York Occasions on each its web site and cell app. Its letterforms, with their thick strokes, open apertures, and enormous x-height, make it simple to learn even at small sizes. There are, nevertheless, some serif fonts that needs to be strictly prevented in app design. Be cautious of overly stylized serif fonts resembling Previous English; with their scripts, shadows, outlines, and ornamentation, these fonts might be notably arduous to learn on small screens.

In distinction, most sans-serif fonts work nicely the place there’s restricted room for copy. They’re typically utilized in cell apps as a result of their clear and easy design makes them simple to learn on small and low-resolution screens. One instance of a extremely legible sans-serif typeface is Roboto, a contemporary, geometric typeface developed by Google for the Android cell working system.

Font Pairings

Font pairing combines completely different fonts that complement each other to create concord and stability inside a design. Nonetheless, utilizing a number of typefaces for cell app content material should be achieved rigorously to make sure that the reader, who might be on the go or multitasking, can take in info rapidly and successfully. Furthermore, designers ought to keep away from utilizing many alternative combos of fonts as these can decelerate web page loading, an enormous deterrent for cell customers.

To make sure that a font pairing enhances your app’s consumer expertise, Toptal designer Karlie Chung suggests utilizing a typographic system that defines the typeface, model, dimension, spacing guidelines, and different parts that you simply’ll use for the several types of copy in your app together with headings, physique copy, captions, menus, and UI buttons. If you happen to’re working with a longtime model, there might already be a system or model information in place that you will want to comply with. Nonetheless, for those who’re creating your personal from scratch, I like to recommend having a look at Kimberly Elam’s e book Typographic Methods and her dialogue of various guidelines and tips for typography and the way to manage textual content inside a digital design.

If you happen to resolve to make use of a single typeface for all textual content, you should utilize completely different font weights, kinds, and sizes so as to add distinction and create a visible hierarchy. Heavier weights needs to be used so as to add emphasis to headings. Generally, medium weights needs to be favored over mild and common weights in app physique copy for optimum readability. Likewise, daring sort can spotlight particular sections of textual content that you simply need to deliver the reader’s consideration to.

Imposter Letters

To make sure excessive readability, keep away from fonts which have “imposters,” or letters that look equivalent facet by facet. A zero might be mistaken for a capital O, and a lowercase L might be confused for a capital I or the #1 on smaller screens. Complicated characters are particularly problematic when displaying content material resembling authentication codes that customers should enter manually. If a number of characters look too comparable, and also you foresee confusion for the reader, contemplate altering your font.

The letters “I,” “L,” and “1” are compared in Verdana, where they’re distinguishable, and in Gill Sans, where they are not.
In some fonts, sure characters look equivalent. Select fonts that get rid of confusion for readers.

Take into account the “Clickability” of Your Textual content

Choosing the right font dimension for headings, subheadings, and physique copy is important for making a harmonious visible expertise and making certain that info is readable—and clickable—on smaller units. When arranging typography for apps, the problem is to make textual content giant sufficient to accommodate contact interactions so customers can precisely faucet hyperlinks or buttons, however not so giant that it takes up your entire display screen or requires extreme web page scrolling.

When it comes to app font dimension, an excellent rule of thumb is a minimal sort dimension of 16 pixels for physique copy with headings being round 1.3 instances bigger than that. (An alternative choice for cell design is to make use of the golden ratio, wherein headings needs to be 1.618 instances bigger than physique copy.)

A mobile screen shows the ideal typography sizes: Headings are at least 1.3 times larger than body copy, which has an ideal size of 16 pixels.
Numerous typography sizes assist with readability and usefulness, whereas additionally establishing a harmonious aesthetic.

Designers may make use of ready-made cell typography techniques and instruments, with predefined properties and kinds. The web typographic scale device Typescale, for instance, lets you visualize your textual content inside the hierarchy of the web page and create different-sized scales relying on the display screen you’re designing for.

Set up a Clear Hierarchy

Appropriate use of font dimension, model, shade, weight, case, and distinction might help customers rapidly determine and perceive what’s most important on the display screen. An efficient typographic hierarchy attracts the attention to crucial copy and offers that means and context to every content material sort (e.g., headings, subheadings, and physique copy). Toptal product designer Brian Carter recommends utilizing a grid system to make sure parts are aligned, nicely proportioned, appropriately spaced, and uncluttered. Some further concerns that will help you set up a coherent rating embody:

Line Spacing for Physique Copy

Correct spacing, together with line peak, letter spacing, phrase spacing, margins, and padding, is essential to readability, particularly on smaller screens with much less white house to information the consumer’s eye from one piece of content material to the following, says Chung. Optimum line spacing (or main) varies relying on the kind of copy. For cell physique copy main needs to be about 1.6 instances the font dimension. This creates extra white house between the strains to keep away from crowding and restrict eye fatigue.

Line Spacing for Headings

To speak hierarchy in your cell design, your headings should stand out in opposition to the accompanying physique copy. A straightforward method to do that is to create house across the heading or to take away house between lengthy titles that run over a number of strains. Perhaps a heading runs two and even three strains on a cell display screen; lowering the main between these strains will make it clear to the reader that the heading is separate from different textual content varieties. As a normal rule for headings, main needs to be round 1.2 instances the font dimension; for subheadings, it needs to be 1.4. In my expertise, one different vital guideline about spacing is illustrated within the graphic under: If a heading is in all caps, the peak of the house between strains ought to match the width of any letter’s stem—or be as much as 1.2 instances its width.

The words “Typography for Apps” and names of letterform attributes: capital letters, baseline,  stem width, and stem.
For cell headings in all caps, the peak of the house between strains needs to be 1 to 1.2 instances the width of any letter’s stem.

Eyebrow Textual content

To draw further consideration to your heading, contemplate including eyebrow textual content, which sits simply above the primary phrases of a heading. This textual content presents a quick clarification of the options or content material and serves as a beneficial device to information customers successfully via the cell interface, facilitating user-friendly navigation and drawing them into the principle content material.

An example of eyebrow text sits above a brief contextual description, and guides readers to the heading “Your Heading Here.”
“Eyebrow textual content” that sits above a heading helps draw the consumer’s consideration to the principle content material and facilitates speedy UI navigation.

In cell design, the intention behind eyebrow textual content is to present readers an instantaneous grasp of what to anticipate on the web page. It permits them to scan the content material and eat it extra rapidly, in accordance with Carter, who has used this function in a number of app designs, together with digital Pockets app Meteor.

Make Your Cell Typography Accessible

There are a number of methods to make sure your cell typography is accessible to all, together with customers with low imaginative and prescient, blindness, shade blindness, and dyslexia. Firstly, keep in mind that lengthy strains of textual content might be troublesome to comply with for low-vision customers or these with a small sight view. Size isn’t normally an issue in portrait mode, because of the slender viewport, however attempt to restrict line size to 80 characters in panorama mode.

Secondly, contemplate providing a handbook possibility for adjusting font dimension to assist customers keep away from eyestrain. Darkish mode can also be a beneficial function for low-vision customers, however be sure that there may be enough distinction between the textual content and background colours. Poor distinction could make textual content arduous to learn, particularly within the shiny mild of a backlit display screen.

When designing typography for apps with display screen readers—assistive software program applications that convert textual content and different on-screen parts into synthesized speech or Braille output—there are some things to recollect. Display screen readers can misread letters which might be very shut collectively or overlap, making serif fonts, italics, and all caps difficult to translate. Very skinny or light-weight fonts are additionally problematic. In a current webinar, Jacinta Oakley, UX designer and advisor for Imaginative and prescient Australia, advised utilizing a humanist sans-serif typeface like Calilbri, Verdana, or Tahoma. These fonts have giant x-heights, ample open house, and distinctive letter shapes, making them supreme for display screen readers. One other font with these traits is Proxima Nova, which has made many high 10 lists for finest fonts for cell and digital UI/UX.

On the left, upper and lower case letter and number examples in Proxima Nova, and on the right, a range of Proxima Nova font weights and styles, and with which types of content to use them.
Accessible in a number of completely different weights and kinds, Proxima Nova is a well-liked UI/UX font that’s utilized by many corporations for cell apps, web sites, and branding supplies.

At all times Check Your Typography

By conducting complete exams on cell typography, designers can transcend in search of bugs to making sure that their chosen fonts, sizes, and kinds improve usability and in the end contribute to an app’s success, says Chung. Instruments like Font Tester, Fonts Ninja, and Typetester can measure readability and legibility, whereas usability and UX testing instruments like UserZoom, UserTesting, and Optimizely allow you to do surveys and polls to collect quantitative and qualitative knowledge.

It’s also possible to search suggestions out of your staff and exterior testers. Whereas the design staff seems to be for and refines visible flaws, exterior testers simulate numerous consumer interactions carried out by way of contact, keyboard, and different inputs to uncover performance errors. When evaluating the usage of typography, testers may also search for sort that’s too small or too giant for the display screen decision. Based mostly on the testers’ suggestions, the design staff can iterate to make sure their designs align with the specified targets.

Cell Typography Pointers: Keep As much as Date

Typography for cell design continues to evolve with the instances and consumer preferences. I urge you to comply with design leaders, be part of design communities, and skim up on cell tendencies with a view to keep updated on the most recent in cell typography. Take into account taking part in designer boards or becoming a member of occasions that debate typography; you may also comply with hashtags and accounts resembling #typography and @typocircle that curate typography content material on X (previously Twitter).

Creating good typography for cell apps goes past making use of basic tips—it’s essential to know customers so we will create a welcoming house the place they’ll work together and interact with our manufacturers and merchandise.
