AlignmentPlacing elements on the same line and positioning them on that line (e.g. left, center or right).
Angular ShapesBoxes, horizontal lines and vertical lines are overused in design such that other angles tend to stand out. For example, the use of triangles.
Asymmetrical BalanceA complex type of balance where both sides are different but equally weighted.
CohesionElements that look like they belong together.
Color HarmonyColors that look like they belong together.
Complexity / New ComplexityThe opposite of minimalism -- designs that are detailed and dense.
ContrastThe use of elements that do not match.
Design DominanceDesigning elements to dramatically stand out.
Focal PointsAreas of emphasis that draw the viewer's attention.
HierarchyEstablishing a hierarchy of elements such as levels of headings in text.
LayoutThe positioning of things such as the furniture in a room.
Leading LinesThe use of lines to direct the viewer's eyes.
LineThe use of lines.
MinimalismThe use of few elements and much space.
MovementThe sense that elements of a design are in motion.
Negative SpaceThe use of a background such as white.
PerspectiveGiving a 2d visual work realistic depth.
ProximityThe closeness of things.
RepetitionThe use of repeated elements.
Rule of ThirdsPlacing a 3x3 grid over your design and placing your focal point on one of the corners of the center box.
ScaleDesigning physical environments to human scale.
Shape & FormThe shape or 3d form of the design and its elements.
SizeThe size and relative size of elements.
Symmetrical BalanceA simple type of balance where both sides of middle are the same.
TransitionThe flow between elements in a design.
Vanishing PointElements that get smaller towards an imaginary horizon line until they disappear altogether. A vanishing point is an art technique that creates perspective.
Visual BalanceGiving both sides of middle an equal weight.
Visual WeightMaking elements appear heavy or light with variations of size, line, color and texture.
