Quick Start

Open the Type Scale tool on HeronTool, choose a preset ratio (e.g., 1.333 or 1.618), and get a complete font-size ladder from headlines to body text. Click any size to preview in real time and copy the corresponding CSS or Figma style code.

Customization & Fine-Tuning

Use the sliders to adjust the base font size and ratio coefficient, observing how the text hierarchy changes. Set min/max size limits to prevent extremes. Also, refer to the font pairing suggestions to choose harmonious font combinations for headings and body.

Export & Integration

Once you've finalized your styles, click "Export" to get sizes for Web (PX/REM/EM) or mobile (PT). Paste the generated code directly into your project files, or use "Copy Styles" to quickly apply to text layers in design tools.
