THE FORM OF THE GRID
ORGANIZATIONAL SYSTEMS
But we really start to see a system emerge in grid construction. What separates a grid system from a basic grid structure is modularity—where a base unit or units, of some size and measure, build(s) larger units. The larger whole is configured from the sum of the constituent parts: a screen and its assets over time, measured in pixels and frames; or a magazine, with its articles and ads in picas and pages. Grid systems help typographers assign active or supporting duty to every pica, pixel, or inch, and to order elements across space and time.

the margin
First they help ensure that all the type that needs to be present and intact is indeed present and intact every tell an ear safe from the page trimmer or web browser frame second they prevent words from getting lost in the gutters up books and from being Luke off on street signs third margins keep our eyes from inadvertent lean flipping off the page or bumping into competing screen text as he read which is annoying. The margins primary function is to define the boundaries of text as a complete and comprehensible entity.

the armature
If elements are indeed like actors, then the Armature is an assortment of connected stage marks that set up interactions among the players. armatures are built through alignment. A basic Armature is a vertical center line balancing horizontal text lines. other schemes are the arc and curve. From spindly webs to radiating spokes, armatures are pliant, so they work brilliantly for straightforward content and one-off productions, such as advertisements and posters.

the grid
Grids are brigades of intersecting, invisible lines that demarcate space; there are organizing schemes as basic to civilization as mark-making. Even the alphabet has been submitted to rationalize grids at various points in history.

CLASSICAL GRIDS
In western civilizations, early book grids Evolved from proportional relationships, particularly the Golden mean, a ratio of 1:1.618, which ostensibly mimics a proportion found in many natural structures- conch shells, for example. The golden rectangle was inherited and applied in various ways to medieval codices, precursors to the books we design and read today. The points found at intersections, when connected, establish margin widths and text areas that harmonize with the page. The classical grid also creates other features that we relate to the form of traditional books, including spacious margins and symmetrical facing pages.

MODERN GRIDS
His design visually sorted both text and image into primary, secondary, and Tertiary levels, based on the relationships that the content required. In short, he considered the parts relative to a whole. The modern grid has evolved to become an organizing structure that contains text blocks, or columns, and ascribes hierarchical roles to typographic elements. The modern grid is distinguishable from classical grids in several ways. First, it builds equal margins rather than progressively wider ones. Second, columns of text separated by gutters established the whole text area, rather than the classical grid's one wide column, or single text area, although the latter also fits within the modern grid scheme. Third, the modern grid accommodates arbitrarily play skylines, typically for the placement of headlines in subheads. Fourth, this grid is designed to support asymmetrical composition. Finally, the modern grid is constructed from mechanical measures, dictated by content needs an machine production standards rather than by notions of proportional correctness.

MODULAR GRID SYSTEMS
A modular grid system is in network of rational spatial divisions and multiple alignments. These divisions are determined from a base unit, or module; the idea to subdivide a rectangular format into organization then sub-units. The typographer first determines an irreducible  element, specifically, a type size and comfortable line space. This fixed measure establishes a base unit that is then extrapolated to build modular fields, sometimes referred to as zones.

grids in space, and in real time
The rationale of grid systems is frequently applied to physical space, and to objects. Placing uniform signage on the floors of a building, for instance, lessons effort for visitors as they try to locate an office on the 16th floor in the north wing of the main building. When layers of assorted text need to exist in both sequential and simultaneous reading spaces, such as signage distributed throughout an airport, a grid system helps travelers to recognize related information easily as they come across each sign within the system. The grid assists the reader by patterning the hierarchy of information.

FORMING AND USING GRIDS
A knowledgeable use of grids simplifies planning and standardized production, so they are fundamental to design and typographic practices. Employing a grid can have economic benefits, such as maximizing resources and minimizing labor. The tools we use and are standard practices of production also sustain grid use. Once a grid and its guiding rules for placement have been designed, they also streamline the task of managing a lot of text. And of course, grids work to facilitate reading if they are mindfully organized and populated with clear visual cues.

physical needs
Text needs room to breathe. It needs adequate space to function well in its physical environment. So, typographers always take stock of the kind of content, the amount of text, and the medium as they begin to settle on an appropriate and functional grid.

KIND OF CONTENT
A primary consideration in building a suitable grid is the kind of content to be contained within it. Specific grids are predisposed to manage specific content, and certain kinds of content inspire certain grids.

AMOUNT OF TEXT
What we can do is expand the grid or reduce the type size to increase the amount of text page. Or we can select a typeface with A narrower set-width. Or decrease the line-spacing. It is conceivable that a book contains so many words, in relation to the maximum physical space and production budget, that the type is forced into an unreadable size.

CLASS OF MEDIUM
It happens that the OED content does also reside on a website.

organizational and navigational needs
Given how most typographers fuss over grids, it can be disheartening to learn that readers hardly notice them, unless their interaction is hindered by the lack of one. Designers can similarly place elements at will within grids, as the arrangement suits organizational, navigational, and communication aims. The structural system grounds the array, while visual characteristics  of elements and their arrangement direct readers through the assortment to access the content they seek.

ROLES AND RULES WITHIN GRIDS
Several types of information need ordering so that readers are able not only to access the content, but also to understand the relationships between the levels. The design of this book, as an immediate example, manages primary, secondary, Tertiary hierarchical levels devised from several divisions of content. The chapter section, one such division, includes a variety of typographic levels, and each level has a role to play: headlines, subheads, body text, captions, and so on. The primer sections, another division, include other levels and rolls. These levels are consistent across all members of the division, so each chapter employees the same typographic rolls in the same way. With so many different but necessary roles, one can begin to comprehend the value of the grid that reduces placement options, and it's rules that help readers recognize the various levels of information.

communication needs
Different circumstances, uses, communication requirements, and so on help typographers to make decisions about the attributes of the grid, and its rules. A monograph designed to communicate the subject of modern architecture might understandably look quite different from one about a contemporary comic-book artist.
