Achieve visual harmony and mathematical precision in your design system with our Type Scale Calculator. A consistent typographic scale is the backbone of a professional UI, ensuring that your headings and body text maintain a clear and logical hierarchy across all screen sizes. Our calculator allows you to define a base font size and choose from several classic ratios—from the subtle Major Second to the dramatic Golden Ratio. As you adjust the parameters, the tool instantly generates a complete scale for H1 through H6, along with small body copy and button sizes. Stop guessing your font sizes. Use our interactive preview to see how your scale looks in a vertical stack or within a sample content layout, then copy the CSS variables or relative REM values directly into your project.

Frequently Asked Questions

A type scale is a set of font sizes that follow a mathematical ratio, ensuring that the visual difference between sizes remains consistent and harmonious.

Subtle ratios like Major Second (1.125) are great for information-dense sites, while the Golden Ratio (1.618) is best for creative or marketing-heavy designs.

REMs are generally preferred for accessibility and responsive design, while pixels are useful for initial layout mockups.
