## Typography Scale Generator

Create beautiful, mathematically harmonious typography scales for your design projects. Our AI generates consistent type hierarchies using proven ratios like the golden ratio, perfect fourth, or major third — complete with pixel values, rem units, and line heights for every step in your scale.

## The Mathematics Behind Beautiful Typography

Typography scales use mathematical ratios derived from music theory and natural proportions. The Perfect Fourth (1.333) mirrors the musical interval, the Golden Ratio (1.618) appears throughout nature and architecture, and the Major Third (1.250) offers balanced contrast. By applying these ratios consistently, each size in your hierarchy relates harmoniously to every other, creating the visual rhythm that distinguishes polished design from amateur work.

## Implementing Your Typography Scale in Design Systems

Once generated, encode your typography scale as design tokens — CSS custom properties or design tool styles. Map each step to a semantic name (display, heading-1, body, caption) rather than using raw sizes. This abstraction lets you adjust the entire scale by changing the base size or ratio without updating individual components. Teams using a tokenized scale ship more consistent UIs and spend less time debating font sizes.

## Frequently asked questions

Short answers for this tool before you move into a full branded assistant.

**What is a typography scale?**

A typography scale is a set of harmoniously proportioned font sizes derived from a mathematical ratio. Just as musical scales create pleasing note relationships, typographic scales create visual harmony between heading levels, body text, and small text. Using a consistent scale ensures your typography feels cohesive and professionally designed rather than arbitrarily sized.

**Which scale ratio should I choose?**

For most web projects, the Perfect Fourth (1.333) or Major Third (1.250) work well — they provide enough contrast between sizes without becoming extreme. The Golden Ratio (1.618) creates dramatic differences suited to editorial designs. Smaller ratios like Minor Second (1.067) work for compact interfaces with subtle size differences. Choose based on how much contrast you need between heading levels.

**Should I use px or rem for font sizes?**

Use rem units for production CSS. Rem units are relative to the root font size, respecting user browser settings for accessibility. Pixels are useful as a reference during design, but rem ensures your typography scales proportionally when users adjust their default font size. Our generator provides both so you can design in pixels and implement in rem.

**How do I handle responsive typography?**

Use fluid typography with CSS clamp to smoothly scale between mobile and desktop sizes. A common approach is reducing your scale ratio by one step on mobile — for example, using Major Third (1.250) on mobile if you use Perfect Fourth (1.333) on desktop. This prevents headings from becoming too large on small screens while maintaining visual hierarchy.

**What line height should I use with my typography scale?**

Line height should decrease as font size increases. Body text (14-18px) typically needs 1.5-1.7 line height for readability. Headings (24px+) work well at 1.1-1.3 because the larger size provides natural spacing. Small text (12px and below) may need 1.6-1.8 to maintain legibility. Our generator calculates optimal line heights for each step in your scale.
