The ratio of a rectangle's width to its height. It is measured by dividing the shorter side length, here "w" or width, by the longer side length, "h" or height. The aspect ratio may be given as either a fraction or as a decimal.
The process of arranging type to make written material readable. The arrangement of type involves decisions about individual letters and words (e.g. line spacing, letter spacing, and word spacing) and more significant page layout decisions (e.g., margins, headline position on the page).
The art and science of arranging information so that it's intuitive to find, easy to navigate, presents a cohesive design, meets accessibility guidelines, looks attractive on any device or screen size and ultimately drives behaviour change.
A portion of an image where the remainder is discarded.
A type of user interface design carefully crafted to trick people into doing things they might not want to do.
A prediction model used in human-computer interaction. It states that the time required to move to a target area rapidly increases as the distance to the target increases. The law was proposed by Paul Fitts, an American psychologist, in 1954 as a mathematical model of movement with limited cognitive capacity.
Fitts hypothesized that one would quickly select its first apparent target when reaching for an object before considering alternatives — a phenomenon called "target fixation." This tendency would increase progressively with increased distance between the subject and object until it eventually became exponential (i.e., too far away).
A group of rules, guidelines, and/or standards designers use when producing artwork or branded projects ensuring that they have the desired appearance and are compliant with usage guidelines.
