Typography Playground
Experiment with font family, weight, size, line height, letter spacing, and measure to understand how typographic variables affect readability and tone.
What this playground does
This typography playground lets you experiment with font family, weight, size, line height, letter spacing, and measure in real time. See how each variable affects readability and tone before applying changes to your project.
How to use it
- Select a font family and weight to establish your base typographic voice.
- Adjust font size and line height to find a comfortable reading combination.
- Fine-tune letter spacing and container width to optimize measure.
- Compare changes side by side with sample headline and paragraph text.
- Read Typography Fundamentals for principles behind each variable.
For deeper context, read the Typography Fundamentals chapter in the Typography Master guide.
Frequently asked questions
- What typography variables affect readability most?
- Font size, line height, measure (line length), and contrast have the largest impact on readability. Letter spacing matters at display sizes. Start with 16px body text, 1.5–1.7 line height, and 45–75 characters per line.
- How do I test typography before implementing in code?
- Use this playground to preview combinations with real content. Once satisfied, copy values into CSS custom properties or export tokens with the Typography Token Exporter tool.
- What line height works best for body text?
- Body text at 16–18px typically needs 1.5–1.7 line height. Headlines use tighter values around 1.1–1.3. Adjust based on typeface, measure, and font size.
