Typography Units

Convert between pixels, points, em, rem, and physical units

About Typography Unit Conversion

Typography units bridge the worlds of digital and print design. Pixels (px) are the fundamental unit of screen displays, while points (pt) originate from the printing industry where 1 point equals 1/72 of an inch. On screen at the standard 96 DPI, one point equals approximately 1.333 pixels. Understanding these relationships is essential for designers working across both digital and print media.

In modern web development, em and rem units provide relative sizing. One em equals the computed font size of the element, while one rem equals the font size of the root element (typically 16px by default). Using rem units creates consistent, accessible designs that respect user font size preferences. Our converter assumes the standard 16px base font size for em and rem calculations.

Physical units (centimeters, millimeters, inches) are primarily used in print design and CSS for print stylesheets. At 96 DPI (the CSS reference pixel density), one inch equals 96 pixels. This converter helps web developers and designers quickly translate between all these interconnected units.
