Understanding Print Points vs Web Pixels & REMs
Digital typesetting bridges the gap between historical print typography and responsive modern web design:
- PostScript Points (pt): Standardized by Adobe in 1984 as exactly $1/72\text{ inch}$. Traditional print documents are set in $10\text{pt}$ to $12\text{pt}$.
- CSS Pixels (px): Standardized by the W3C as $1/96\text{ inch}$. Therefore, $1\text{ pt} = \frac{96}{72}\text{ px} = 1.3333\text{ px}$.
- REM (Root EM): Scalable CSS unit proportional to the root `` element's `font-size` ($1\text{rem} = \text{Base px}$). Crucial for accessible web applications allowing user zoom.
