Text is one of the most fundamental elements in UI design. It communicates information, guides users through applications, and plays a critical role in creating a seamless and intuitive user experience. A thoughtfully designed typography system can significantly enhance readability, efficiency, and the overall aesthetic of an interface.
In my work as a UX/UI Designer, I’ve developed typography systems guided by principles that ensure both function and form are prioritized. By focusing on dynamic order, natural logarithms, and temperament, I aim to create text systems that are not only visually appealing but also practical for everyday use.
When crafting a font system for a visual interface, I consider these five essential aspects:
1. Font Family Selection
Choosing the right font family is critical for consistency and readability across platforms. I ensure to provide alternative font libraries to guarantee stability, even across different browsers and devices. For example:
font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Helvetica Neue", "Arial", "Noto Sans", sans-serif;
2. Base Font Size for Optimal Reading
The base font size in a design is fundamental to creating a comfortable reading experience. I use an updated base font size of 14px, optimized for common display monitors and supported by research on viewing angles and screen distance (approximately 50 cm for most users). These considerations ensure a balance between readability and efficiency.
3. Font Scale & Line Height
A font scale paired with carefully calculated line heights contributes to an ordered and harmonious text structure. For instance, a 14px font size may pair with a 22px line height, providing the right amount of spacing for readability while avoiding clutter. Here’s a quick example of scaling:
- Font Size: 12px, 14px, 16px, 20px
- Line Height: 20px, 22px, 24px, 28px
4. Font Weight and Hierarchy
Creating a clear hierarchy is essential for guiding the user’s attention. I typically select font weights like 400 (regular), 500 (medium), and 600 (semibold) to maintain balance and restraint. These weights are applied depending on the emphasis needed, ensuring both structure and visual harmony.
5. Font Color for Accessibility
Maintaining appropriate contrast ratios is non-negotiable for accessible designs. I strive for an AAA contrast level, adhering to WCAG standards, which ensures a minimum ratio of 7:1 between text and background colors. This guarantees that all users, including those with visual impairments, can comfortably read the content.
Typography is not just about aesthetics—it’s about creating a functional system that enhances communication while staying visually appealing. I believe that great typography in UI/UX design doesn’t just support the content—it amplifies it.
