Glossary » grid
(graphic design) a system of templates used as a framework to create a document with uniform layouts between pages while still allowing each page to adapt to its content. The grid defines positions for standard elements on the page, margins, proportions, spacing, and edges along which elements will be aligned.
(computer graphics) in drawing software, a grid defines a series of visible or invisible, horizontal and vertical, uniformly-spaced edges for easy alignment of elements on a page. Autogrid features force all mouse input on the drawing surface to fall along those edges.
