How to use this tool
- Choose minimum and maximum font sizes.
- Set the viewport range over which the type should scale.
- Review the live text preview.
- Copy the generated CSS and test it at browser zoom levels.
Understanding the result
Fluid sizing can reduce abrupt breakpoint changes, but it does not replace typography decisions about line length, spacing, hierarchy and user zoom.
Practical guidance
Keep body text comfortably readable, avoid extreme scaling and test at 200% browser zoom. Use relative units for text wherever practical.
