pica to inch – How to convert pc to in
Converting pica to inch (pc to in) is essential in typography, printing, and graphic design. While the pica is a traditional unit for measuring type and layout, the inch is more widely used in everyday measurements and printing specifications. This conversion helps bridge the gap between design precision and practical production.
What is a pica (pc)?
A pica (symbol pc) is a unit of length commonly used in typography and publishing. By definition, 1 pica = 12 points = ¹⁄₆ inch. Picas are primarily used to measure column widths, margins, and other design elements in print layouts. For example, a standard magazine column might be around 12–14 picas wide.
What is an inch (in)?
An inch (symbol in) is a widely recognized imperial unit of length equal to 25.4 millimeters or ¹⁄₁₂ foot. In design and publishing, inches are used for paper sizes, margins, and print dimensions. For example, the common U.S. Letter size is 8.5 × 11 inches.
Conversion formula: pica to inch
The relationship between picas and inches is straightforward:
-
1 pica = ¹⁄₆ in ≈ 0.1667 in -
1 in = 6 picas
Example: 18 pc ÷ 6 = 3 in.

Do you know?
-
Pica fact: The modern pica system was standardized by the American Type Founders Company in the late 19th century, ensuring consistency across printing presses.
-
Inch fact: The inch was historically based on the width of a man’s thumb, but it was standardized internationally to 25.4 mm in 1959.
-
Pica fact: In digital publishing, many software programs like Adobe InDesign still allow layout dimensions to be set in picas and points.
-
Inch fact: Screen sizes are universally advertised in inches — a 27-inch monitor, for instance, is measured diagonally.
From typesetters’ trays to modern design software
In the era of movable type, printers needed a standard way to measure text and layouts. The pica became the unit of choice, dividing the page into manageable pieces for typesetters. A line of type might be 30 picas wide, with margins measured in fractions of picas.
As printing technology evolved, the inch became more prominent because it tied into paper dimensions, press machinery, and later digital design standards. By the 20th century, printers often had to convert between picas and inches daily.
When desktop publishing emerged in the 1980s with software like Aldus PageMaker, the tradition of picas continued. Designers could still work in the familiar pica/point system, while final print dimensions were calculated in inches for presses. This seamless link between pc and in is one reason why typography traditions survived into the digital era.
Today, even though many designers work with pixels on screens, picas remain in professional use, especially in editorial and book publishing. Knowing how to convert pica to inch ensures smooth collaboration between designers, printers, and publishers across the globe.
