Frequently Asked Questions
Everything you need to know about using this application.
What is the CSS clamp() function?
The CSS clamp() function defines a value by clamping a middle value between a minimum and a maximum range, enabling fluid typography that automatically scales based on viewport width.
How do I use this CSS clamp calculator?
Simply input your desired minimum font size, maximum font size, and the viewport range. The tool automatically computes the mathematically correct clamp() syntax for your stylesheet.
Why use clamp() for typography instead of media queries?
