A few notes from Josef Muller-Brockmann’s Grid Systems in Graphic Design
Grid divides 2D space into smaller fields. Fields may be the same or different in size. Vertical distance between fields: at least 1 line of text. Horizontal distance between fields depends on size of type and illustrations used. The smallest illustration corresponds to the smallest grid field (???) All illustrations, photos, stats, etc. have the size of 1, 2, 3, or 4 grid fields. The fewer the differences in size of the illustrations, the quieter the impressed created by the design. Standard typefaces listed in the book: Garamond, Caslon, Bakersville, Bedoni, Clarendon, Berthhold, Times, Helvetica, Univers. Columns should be 10 words wide. Margins of the same size never result in interesting design.
