The relation or adaptation of one portion to another, or to the whole, as respect magnitude, quantity, or degree; comparative relation; ratio; as, the proportion of the parts of a building, or of the body.
The equality or similarity of ratios, especially of geometrical ratios; or a relation among quantities such that the quotient of the first divided by the second is equal to that of the third divided by the fourth; -- called also geometrical proportion, in distinction from arithmetical proportion, or that in which the difference of the first and second is equal to the difference of the third and fourth.
A comparative size relationship between several objects or between the parts of a single object or person. In drawing, for example, watch for the correct relationship of the size of the head and the body.
Scale or relationship of one part of a work of art to the other and to the whole. Figure (adult seven-and-a-half heads high). Three-and-a-half heads from waist to top of head; four from waist to ties. Arms fall at mid-thigh. Portrait. Eyes are one-half distance from top of head. Nose is one-half distance between eyes and chin. Mouth is one-half distance between nose and chin.
harmonious arrangement or relation of parts or elements within a whole (as in a design); "in all perfectly beautiful objects there is found the opposition of one part to another and a reciprocal balance"- John Ruskin
A term used to describe how symmetrical the various parts of a diamond are in relation to each other and the rest of the diamond. All Hearts On Fire diamonds earn the grade of "0" for excellent proportion from the American Gem Society's grading lab.
A special type of ratio expressing a relationship between the part and the whole. The numerator represents a portion of the total; the denominator is the total. For example, five male health workers out of a total of 15 health workers make a proportion.
Type of ratio in which the numerator is included in the denominator. A proportion is calculated by dividing the number of people with a common characteristic at a given time period by the total population that shares the same event in the same time period.
The proportions of a diamond are very important, so that the maximum amount of light be reflected off and out of a stone. Proportion is the relationship between the angles of the facets of the crown and pavilion.
A portion of a population in relation to another portion of the population or to the population as a whole. Proportions are a special type of ratio in which the denominator always includes the numerator. (See also ratio.)
The harmonious relationship of the size of one element to the size of another element or of a space it shares; also, to adjust so that proper relations between parts are attained. Two items of different sizes are considered proportional to each other when the ratio of their dimensions to each other are equal..
Architectural practice has often used proportional systems to generate or constrain the forms considered suitable for inclusion in a building. In almost every building tradition there is a system of mathematical relations which govern the relationships between aspects of the design. These systems of proportion are often quite simple; whole number ratios or easily constructed geometric shapes (such as the vesica piscis or the golden ratio).
Number of actual occurrences of an event divided by number of occurrences possible for that event. EX: If nine restorations are placed and three fail, the proportion of failing restorations is .333. Proportions can only take values between 0 and 1 (cannot be negative). Abbreviated p (by convention q is the complementary proportion, 1 â€“ p.) [See also probability
