For developers and technical teams.
Enter a nonnegative source value, choose CSS px or rem and supply the root font size in CSS px for the page you mean. A root of 16px is only an example, not a universal rule. Use a decimal period in either language. Source must be 0–10,000; root must be 4–96px. The CSS-ready result has at most six decimals and is marked approximate if rounded. A nonzero value too small to display is rejected. Copy or download the text report. CSS px are not physical display pixels; converting units does not certify accessibility.
