We have come to learn that typography does a whole lot more than just make a product pretty in our design process. It influences the way users perceive the content, the speed at which they can get information, and the amount of confidence they can act upon.
By creating, experimenting and refining a number of digital products, our design team has established a typography playbook that continues to deliver higher conversions and engagement with users.
In this article, we are going to offer our 10 best typography tips, which are practical, tested and experience-based.
1. Choosing Readable, UI-Optimized Fonts
The most excellent typography begins with appropriate font choice.
During the initial work we were lured by fonts that appeared to be fashionable but failed to work well in real-life UI application, particularly in small screens and low resolutions. We have been taught to give priority to fonts that are digital interface specific.
Inter, Roboto, SF Pro, and Open Sans have become our favorite fonts, as:
They are responsive.
They are crisp in small portions.
They provide various weights to be flexible.
A practical project example: In one of the dashboards we designed in the field of finance, we did use Poppins because of its modern appearance. However, during testing tables and small labels on mobile, we observed that users had difficulties reading them. The change to Inter made legibility much better and friction lower.
Our tip: Don t finalize fonts in your design system without testing them in different weights, sizes and on mobile, tablet and desktop.
2. Limiting Typefaces or Font Families
Trust and clarity are a result of consistency.
We have experienced designs that have become messy when there are numerous fonts used. The extra fonts do not make it elegant, they make it messy.
Our guideline: Use only one main font and (as an exception) one secondary font to be used as accents.
The reason why we recommend it:
It brings visual harmony.
It assists users to concentrate on content, but not the unwanted switch in style.
It makes handoffs and development of designs simple.
An actual project example: On one of the social media applications we developed, a consistent font family on all the elements provided a sense of unity to the platform and enhanced the user experience during content scanning.
Our tip: When you are about to add a secondary font, question it: Does this clarify or is it merely decorative? Unless it is contributing functionality it is contributing noise.
3. Applying a Type Scale
Structure beats random sizing.
The first problem we had when we began to create typography systems was that we randomly chose text sizes because they were what looked right on each screen. The result? Rhythmic and visual ill-flow.
We now use a type scale all the time, which is a set of font sizes that we predetermine, that are mathematically proportional to each other, and provide a harmonious rhythm to the interface.
The modular scales we use are often:
12px, 14px, 16px, 20px, 24px, 32px
This system:
Enhances visual consistency
Makes design choices straightforward
Makes responsive scaling predictable
An actual project scenario: A structured type scale was introduced in an e-commerce project and kept the whole team (designers, developers, QA) on the same size throughout the pages and components without the need to guess the same sizes twice.
Our tip: Type scale calculators or keep it simple by using ratios such as 1.25x or 1.333x. Record the scale in your design system to ensure that it is easy to implement.
4. Setting a Clear Hierarchy
The eye should be led through typography.
It has been one of the largest lessons we have learned that typography is a form of visual storytelling. It informs the users on what to look first, second and third. In the absence of a definite hierarchy, users are lost or overwhelmed.
We make hierarchy by:
Font size
Font weight
Color emphasis
Spacing above and below elements
An actual case scenario: We implemented a strong hierarchy on a mobile banking application with the account balance being the biggest, boldest text, the secondary options such as the Transfer and Pay Bills options being smaller but bold text, and the informational text being smaller and lighter.
This assisted the users to intuitively locate important actions, which increased the completion rate of tasks.
Our tip: Squint and look at your screens, can you still see what is most important? Otherwise, the hierarchy is not transparent enough.
5. Using proper Line-Height and Tracking between Letters
Give your typography space to breath.
We have come to know throughout the years that text must have space in order to be comfortable. Cluttered text causes more eye strain and less understanding, particularly on mobile.
Our common standards:
Body text: line-height: 1.4x to 1.6x
Letter-spacing (tracking): A small positive value enhances readability, particularly on upper case and smaller fonts
Actual project case: In a long form blog section, raising the line-height of 1.2 to 1.5 made the copy much easier to read and boosted session duration by 15%.
Our tip: Be particularly careful with tight line-heights and negative letter-spacing, they may appear tidy, but usually damage legibility.
6. Setting proper Text Alignment
Readability can be determined by alignment.
The one thing we have always discovered is that left-aligned text is most effective in most of the UI designs particularly in the screens that are content-heavy. It offers predictive initial positions, and natural reading.
Center-aligned text is attractive on titles or hero modules, but if applied in paragraphs or lists, it interrupts the scanning.
An actual project case: On a help center page, the change of the center-aligned FAQs to the left-aligned saved users a lot of time in searching answers.
Our tip: Center alignment should be used sparingly- short heading or splash screens. Use left alignment on anything that the users need to read or scan fast.
7. Selecting proper contrast and colors for better accessibility
Accessibility isn’t optional, it’s essential.
In some of our earlier projects, we prioritized aesthetics over accessibility, choosing subtle text colors that looked great in perfect lighting but failed in real-world usage.
We now always:
Ensure minimum contrast ratios (4.5:1 for body text) as per WCAG guidelines
Test color combinations across different backgrounds
Consider colorblind accessibility.
A real project example: In a food delivery app, we had to darken gray text that initially had a low contrast ratio. Post-adjustment, readability improved dramatically, especially for users on low-brightness settings.
Our tip: Use contrast checkers and test in both dark and light modes. Design for all users, not just those with perfect vision.
8. Avoid all caps when possible
All caps may be considered aggressive and read slowly.
We have seen that upper case lettering removes the shapes of the words that we perceive unconsciously as we read. This reduces the reading speed and may create the impression of the UI being heavy-handed.
Now we restrict all caps to:
Small labels
Short call to action buttons
Occasional emphasis where attention-grabbing is critical
A real project example: On a social site, switching the labels on all the buttons to sentence case (“Post comment”) instead of all caps (“POST COMMENT”) made the site seem more chatty and inviting.
Our tip: Never use all caps in paragraphs or in vital information, only when you really need to add weight or urgency.
9. Use Consistent Spacing Systems
The clean design is the silent structure of spacing.
A clear system of spacing, usually on a grid of 4px or 8px, is one of the things that our team stresses. Having different spacing is visually distracting and usually interrupts the flow of a layout.
We standardize:
Vertical distance between heading, paragraphs and buttons
Margins and paddings between components
Text block gaps in line and paragraphs
Actual project example: During the redesign of a B2B platform, the overall typography spacing system was changed to an 8px system, which had a profound effect on the visual alignment, lessening the design review feedback, and giving the product a feeling of polish.
Our tip: Embed your spacing system in your design tokens and follow it through your project lifecycle.
10. Document all the rules you’ve decided in a Style Guide
A system is only helpful when everybody can abide by it.
At the beginning of our design process, we were using memory and disorganized Figma files, which was a mistake. The result? Screen and platform inconsistencies.
Now we always:
Document typography scales
Name font families, weights and sizes
Detail line-heights, letter-spacing, and alignment rules
Add accessibility color combinations
An actual project scenario: In the process of developing a cross-platform ERP system, we simply needed a more detailed typography section in our design system, which reduced hours of handovers between design, development, and QA teams.
Our tip: Consider your typography documentation a living documentation. Maintain it as your system changes.
Final Thoughts
Typography is a lever that is usually underestimated, but in our experience, it is one of the most effective to increase usability, drive conversion, and influence brand perception.
When we steadily apply these principles, our team has managed to create interfaces that are intuitive, balanced, and accessible.
These are not only theory-based but also are based upon many hundreds of hours of designing, testing, and refining actual products.
