Why typography scale matters in UI design
Typography is one of those elements that can make or break a design especially when working on blogs and user interfaces. When I first began creating type scales it felt a little like fumbling in the dark. Lots of guessing tweaking and second guessing. You might know that feeling too. Figuring out how many text sizes are actually needed and how to properly name them, for yourself and your team, is a real challenge.

How many text sizes should you use?
In most cases starting with four to seven distinct text sizes works well. This range typically includes everything from large display headers that draw attention to small captions or labels that offer additional context. More complex systems might have additional sizes but keeping it simple avoids inconsistency and clutter. At least that is what I have found helps me stay focused and keeps designs cleaner.
Choosing the right modular ratio
When building a scale it helps to work with ratios that define how much bigger or smaller each step is. Popular ratios include the minor third, perfect fourth, and golden ratio among others. The minor third is subtle and great for calm balanced text heavy designs. The golden ratio makes bigger jumps creating an organic feel that some designers favour. Personally I prefer the perfect fourth. It has enough contrast to create hierarchy without feeling like it is shouting for attention.
Best practices for naming text styles
Naming text styles might seem minor but it can cause big headaches down the line. Rather than naming styles small, medium, large which quickly becomes confusing especially in teams it is better to use semantic names tied to the role each text plays. For example display extra large for big headers heading medium for subtitles and body small for captions. This kind of naming makes it much easier for collaboration and communicating design intent.
Rounding font sizes and line heights
A detail many overlook is rounding off font sizes and line heights to whole numbers. It might sound small but it does affect the clarity and rendering of text across browsers and devices. Fractional font sizes can lead to small but noticeable inconsistencies. Rounded values lead to cleaner visuals and often simpler implementation in CSS and development workflows.
How to build a typography system in Figma
Start with your base font size often sixteen pixels for web. Use your preferred modular ratio to set up text styles ascending and descending from this base. Organize these styles in Figma or your tool of choice with clear semantic names and consistent spacing. Check your type scale in real UI contexts and across various screen sizes to ensure it reads well and feels balanced. Iteration is key here and trusting your eyes helps.
Testing your typography scale across devices
Test your typography system in different scenarios. Text that looks great on desktop might feel cramped on mobile or tablets. Multi line headings require more care with line height and letter spacing. Keep checking and refining your scale in various breakpoints and environments so your design stays legible and visually pleasing everywhere it appears.
One final point
Typography scale affects every UI and blog layout. There is no single perfect scale. It is about mastering principles and adapting as you gain more experience. Typography like all design is never really finished it evolves and takes shape with every project you touch. I find it genuinely interesting and I hope you do too.
