Choosing fonts is one of the most important decisions you’ll make when designing a user interface. The right typefaces can enhance user experience and support your brand, while poor font choices may negatively impact readability, usability and your company’s image. With so many options on the market, it’s not always easy to narrow down fonts that will work best. In this article, I’ll explore several key points to consider when identifying fonts for your UI design.
Consider Your Content Type
The first thing to think about is the type of content users will be consuming through your interface. Font choices that may work well for headings or calls-to-action may not be the best pick for long blocks of paragraphs. For example, bodies of dense text are often best served by high-quality sans serif fonts like Arial, Helvetica or Verdana that maximize legibility. On the other hand, bolder or decorative fonts can help headlines and buttons really pop. And serif fonts like Georgia may also support easy reading of longer passages.
Match Your Brand Personality
You’ll also want to select typefaces that align with the overall tone and personality of your brand. A playful, colorful children’s app could showcase lively, hand-drawn inspired fonts while a formal financial website may stick to neat, classic sans serifs. Your font choices should complement rather than clash with your desired aesthetic. Spend time experimenting with different typeface-imagery pairings and colors to find the perfect fit.
Consider Screen Size Variations
Another key factor to think about is how your chosen fonts will render at different screen sizes. While a typeface may look elegant on desktop, the details that make it attractive could become too subtle or crowded on smaller mobile screens. Be sure to preview your font combinations across a range of typical viewports to ensure readability, clarity and balance remain consistent.
Focus on Accessibility
Accessibility of your UI content is also crucial. Stick to widely available system fonts whenever possible to maximize readability for all users. Additionally, pay attention to factors like appropriate font weight, size and color contrast, which impact accessibility for individuals with visual impairments. Your design should aim to be inclusive for all.
Browse Preferred Sources
Now that you understand the important evaluation criteria, it’s time to start browsing available options. Some trusted choices to consider searching through include Google Fonts, Adobe Fonts and Fonts.com. You can sort and filter each catalogue to zero in on typefaces aligned with your goals. Be sure to download generous free samples before making your decisions.
Draw Inspiration From Others
Once you have a preliminary list of prospect fonts, it can help to scan what others in your industry are using. Look at competitors’ sites, high-profile brands or award-winning designs for inspirations. However, take care not to directly replicate – you want a style uniquely your own. Observing experts can spark new ideas to consider adding to your evaluation process.
Test Thoroughly Before Finalizing
With research complete, you may have a shortlist of top 2-3 font combinations that seem fitting. But it’s critical at this stage to preview mockups with real content using each prospects across all intended pages and screens. Sample texts may look different than full designs. Continue tweaking and testing alternatives until confident your UI will shine.
By keeping these points top of mind, you can ensure choosing the optimal typefaces for your interface in terms of usability, brand and development best practices. Let me know if you need any other UI or user experience design tips!

Ideally A/B test readability at various common text sizes (14-18px). 16px is often a safe minimum for paragraph text.

Freely available fonts like Google Fonts don’t require attribution. For commercial use, confirm you’re licensed or purchase commercially-licensable alternatives.

Readability tests show serifs can aid print but hawk a sans style for digital. Consider your content and balance legibility with matching your visual style.
