About the Unit

Pica (pc): The pica unit (pc) is another traditional typographic unit used in printing. 1pc is equivalent to 12 points (pt), and its origin dates back to early typographic systems. Although rarely used in web design, the pica unit still finds application in typography and graphic design, especially when working with print systems and physical documents. When using the pc unit, you are essentially working with a value that is larger than the point, which can be helpful in typographic projects where font sizes or other elements need to be larger. In CSS, the pica unit can be used to define font sizes, but it is more commonly found in print contexts rather than in digital web design. Its usefulness is limited in most digital designs, as most projects benefit more from relative units.

Pro Tip: pc → cm

1pc = 0.4233cm. Convert pica to cm for print measurements.
