When to Use 15px (0.9375rem)

A value of 15px (0.9375rem) is commonly used for body text, paragraph text, default browser font size, and standard UI text. In responsive web design, using 0.9375rem instead of 15px ensures your body and paragraph text scale proportionally when users change their browser font size settings.

Why Use REM?

REM units are relative to the root element's font-size, making them ideal for accessible, responsive designs. When you write 0.9375rem instead of 15px, your layout respects user preferences — if someone sets their browser to a larger font size for readability, all your rem-based values scale up proportionally.
