Typography

派卡

定义

排版单位，等于12磅或恰好1/6英寸（约4.233 mm），主要用于度量栏宽和其他版面尺寸。

解释

Picas have been a standard unit in print publishing for centuries and remain in use in professional page layout software such as Adobe InDesign. A standard US letter page (8.5 inches wide) is 51 picas wide. The unit bridges points (too small for column measurements) and inches (too coarse for fine typographic work), making it practical for specifying margins and gutter widths in book and magazine design.
