PPI stands for Point Per Inch. PPI is the number of dots per inch in a printer's resolution or the number of pixels per inch in a monitor's screen resolution. The more PPI, the higher your image quality will be as it becomes sharper and clearer. The lower your PPI, the lower your image quality will be, and the more likely you'll see individual pixels in an image.
Colours that directly across the colour wheel, like blue and orange. When you put these colours next to each other, they make a great contrast together. Complementary colours are often found in nature.
A small picture or design that represents an idea, function, or some other type of visual concept. For example, in computer graphics and web development, an icon is a pictorial representation of a program or file type.
In typography, a bowl is a curved shape used to control the area of white space.
The area of negative space around and between elements in a design.
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 collage consisting of images, colours and text that is assembled to convey an idea or theme.
A system of columns and rows designers use to create layouts. It's used in graphic design and web development to align elements for easy use on the page. Grids are a key part of design because they help you create balance, rhythm, proportion and hierarchy in your layout.
A unit for defining the size of a font. It's not a distance; this unit's measurement is only relative to the typeface's design.
A type of user interface design carefully crafted to trick people into doing things they might not want to do.
A design technique employed on websites and mobile apps that encourages users to scroll to view additional content.
