    Choose a base size

    Select a base font size that matches your product's reading density, from compact dashboards to spacious editorial layouts.

  2. 2

    Pick a scale ratio

    Choose a modular scale ratio like Major Third or Perfect Fourth to generate a harmonious type hierarchy.

  3. 3

    Adjust typography rhythm

    Fine-tune font weight, line height, and letter spacing to improve readability and visual balance.

  4. 4

    Preview in real layouts

    Test your typography system across website, mobile, blog, and dashboard previews to validate hierarchy and usability.

  5. 5

    Export your tokens

    Export your final typography system as CSS variables, Tailwind config, JSON, or AI prompts for production workflows.

WHY TYPOGRAPHY BUILDER

More Than a Typography Calculator

Most typography tools only generate font sizes. Typography Builder helps you build complete, production-ready typography systems for modern design workflows.

Modular Scale System

Generate mathematically balanced typography scales using proven ratios like Major Third, Perfect Fourth, and Golden Ratio.

Real-World Previews

Preview your typography across websites, mobile apps, dashboards, and blog layouts instead of static specimen sheets.

Health Diagnostics

Instantly detect readability, hierarchy, and mobile scaling issues before shipping your design system.

Design Token Export

Export production-ready typography tokens for CSS variables, Tailwind, and JSON workflows.

AI Workflow Ready

Generate AI-friendly typography rules that help tools like Claude, Cursor, and GPT maintain visual consistency.

System-Level Consistency

Create a unified typography language for headings, body text, labels, captions, and UI components.

Unlike basic type scale calculators, Typography Builder creates a complete typography system with previews, diagnostics, and AI-ready design tokens.

Typography Builder FAQ

Common questions about typography scales, ratios, exports, and using the tool.

What is a typography scale?
A typography scale is a structured set of font sizes built from a base size and a mathematical ratio. Instead of choosing random font sizes, a scale creates consistent visual hierarchy between headings, body text, labels, and captions. This improves readability and helps create a more polished design system.
What is a modular scale in typography?
A modular scale generates font sizes by multiplying a base font size by a consistent ratio such as 1.2, 1.25, or 1.333. For example, starting with 16px and using a 1.25 ratio creates a harmonious progression for headings and body text. Modular scales help maintain rhythm and consistency across interfaces.
How does Typography Builder work?
Typography Builder lets you choose a base font size, modular scale ratio, and reading style preset to generate a complete typography system. You can fine-tune font weight, line height, and letter spacing, preview the results in real-world layouts, and export the final typography tokens for development workflows.
What makes Typography Builder different from a typography calculator?
Most typography calculators only generate font size values. Typography Builder goes further by generating a complete typography system with responsive scaling, readability diagnostics, live previews, and export formats for CSS, Tailwind, JSON, and AI-assisted frontend workflows.
Which typography scale ratio should I use?
The best scale ratio depends on your product: Minor Third (1.2) is great for dashboards and dense interfaces; Major Third (1.25) is the best all-purpose choice for SaaS products; Perfect Fourth (1.333) gives strong visual hierarchy for marketing pages; and the Golden Ratio (1.618) creates dramatic contrast for editorial designs. For most modern products, Major Third offers the best balance.
Can I use these typography tokens in Tailwind CSS?
Yes. Typography Builder supports export formats for Tailwind CSS, including structured typography tokens that can be integrated into your design system. This makes it easier to maintain consistent typography across components and layouts.
Can I use Typography Builder with AI coding tools like Claude or Cursor?
Yes. Typography Builder can export AI-friendly typography instructions and token data that help AI coding tools follow consistent font sizes, hierarchy, spacing, and reading rhythm. This reduces inconsistent typography in AI-generated interfaces.
Why is typography important in design systems?
Typography affects readability, visual hierarchy, accessibility, and user experience. A well-defined typography system ensures consistent headings, body text, labels, and UI elements across every screen, making interfaces easier to scan and more professional.

With your type scale in place, add matching font pairings, spacing, and color for a cohesive frontend design language.
