When to Use 34px (2.125rem)

A value of 34px (2.125rem) is commonly used for section headings (h2, h3), modal titles, and prominent UI text. In responsive web design, using 2.125rem instead of 34px ensures your headings 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 2.125rem instead of 34px, 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.
