72x84

72x84 denotes a rectangular dimension expressed as width by height. The numbers describe size, but the actual meaning depends on the units specified in context. In design, printing, and construction, common units for this pair are inches for large-format media such as posters and banners, and centimeters or millimeters in metric workflows.

Mathematically, 72x84 is the ordered pair (72, 84). The product 72×84 equals 6048. The greatest common divisor of 72 and 84 is 12, and their least common multiple is 504. The ratio 72:84 simplifies to 6:7, indicating an aspect ratio where the height is 7 parts for every 6 parts of width.

Practical uses and conversions vary by unit. A 72x84 inch size equals about 1.83 by 2.13 meters, with an area of roughly 3.9 square meters, a common dimension for large posters, banners, or stage backdrops. If the same numbers are given in centimeters, 72 cm by 84 cm describes a poster about 0.60 square meters in area. In millimeters, 72 mm by 84 mm would be a small component rather than a display size. Because units do not inherently appear with the numbers, it is essential to specify them to avoid ambiguity.

Overall, 72x84 is a flexible size descriptor used across industries to denote width and height, with its meaning anchored by the units applied to the pair.
