About these units
Pica (pica)
A pica is another typographic unit, equal to 12 points, or 1/6 of an inch, making it larger and more suited to structural layout than to fine detail. Picas are commonly used to measure text blocks, column widths, margins, and line lengths in print and digital page design. The pica originated alongside the point in printing traditions stretching back to the 18th and 19th centuries. It offered a convenient intermediate scale—small enough for precise adjustments but large enough for practical page design. When newspapers became widespread, picas helped designers rapidly calculate column grids and organize dense printed pages. Even as publishing tools evolved into software like Adobe InDesign and LaTeX, picas remain deeply integrated into the workflow of book designers, typographers, and professional printers. They are part of a system that allows page elements to be arranged with precision, ensuring that every visual aspect of a document aligns harmoniously.
Long Reed (long reed)
The long reed is a traditional unit of length used in Egypt and other ancient cultures, roughly equivalent to 2 cubits. It was employed in surveying, architecture, and the measurement of agricultural fields. The unit's length made it suitable for laying out longer distances with relatively few measurements, especially in river valley contexts where precision at large scales was important for irrigation and crop management. Historical records show the long reed in use for temple construction, pyramidal measurements, and land division, illustrating the practical integration of human-based units into early engineering practices.
