Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale.
Hierarchical proportion is a technique used in art, mostly in sculpture and painting, in which the artist uses unnatural proportion or scale to depict the relative importance of the figures in the artwork. For example, in Egyptian times, people of higher status would sometimes be drawn or sculpted larger than those of lower status.
In 1961, Danish Egyptologist Erik Iverson described a canon of proportions in classical Egyptian painting. [2] This work was based on still-detectable grid lines on tomb paintings: he determined that the grid was 18 cells high, with the base-line at the soles of the feet and the top of the grid aligned with hair line, [3] and the navel at the eleventh line.

In classical architecture, proportions were set by the radii of columns. Proportion is a central principle of architectural theory and an important connection between mathematics and art. It is the visual effect of the relationship of the various objects and spaces that make up a structure to one another and to the whole.
Human proportions marked out in an illustration from a 20th-century anatomy text-book. Hermann Braus, 1921 Drawing of a human male, showing the order of measurement in preparation for a figurative art work (Lantéri, 1903) [1] It is usually important in figure drawing to draw the human figure in proportion.
Plans are usually "scale drawings", meaning that the plans are drawn at specific ratio relative to the actual size of the place or object. Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:50 (1:48 or 1 ⁄ 4 ″ = 1′ 0″) whereas a detailed view may be drawn at 1:25 (1:24 or 1 ⁄ 2 ...
For example, a work of art is said to be aesthetically pleasing to the eye if the elements within the work are arranged in a balanced compositional way. [10] However, there are artists such as Salvador Dalí who aim to disrupt traditional composition and challenge the viewer to rethink balance and design elements within art works.
As another example, Carlos Chanfón Olmos states that the sculpture of King Gudea (c. 2350 BC) has golden proportions between all of its secondary elements repeated many times at its base. [3] The Great Pyramid of Giza (constructed c. 2570 BC by Hemiunu) exhibits the golden ratio according to various pyramidologists, including Charles Funck-Hellet.
