Aspect ratioThe aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction.

RectangleIn Euclidean plane geometry, a rectangle is a rectilinearconvex polygon or a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square. The term "" is used to refer to a non-square rectangle. A rectangle with verticesABCD would be denoted as ABCD.ISO 217The ISO 217:2013 standard defines the RA and SRA paper formats. OverviewThese paper series are untrimmed raw paper. RA stands for "raw format A" and SRA stands for "supplementary raw format A". The RA and SRA formats are slightly larger than the corresponding A series formats. This allows bleed (ink to the edge) on printed material that will be later cut down to size. These paper sheets will after printing and binding be cut to match the A format.

Square root of 2The square root of 2 (approximately 1.4142) is the positive real number that, when multiplied by itself or squared, equals the number 2. It may be written as 2{\displaystyle {\sqrt {2}}} or 21/2{\displaystyle 2^{1/2}}. It is an algebraic number, and therefore not a transcendental number. Technically, it should be called the principalsquare root of 2, to distinguish it from the negative number with the same property.
