40x48

40x48 denotes a rectangle defined by a width of 40 units and a height of 48 units. The meaning of the numbers depends on the units used in a given context, such as inches, centimeters, or millimeters. This size notation is common in fields involving physical templates, such as framing, print production, photography, and architecture, where precise width-by-height dimensions are required. The orientation implied by 40x48 is portrait (taller than it is wide) when the units are consistent.

When expressed in inches, 40x48 inches covers 1,920 square inches of area, which is about 13.33 square feet. The diagonal measures roughly 62.4 inches. The aspect ratio simplifies to 5:6, since 40:48 reduces by a common factor of 8. In metric terms, 40x48 cm equals 0.4 by 0.48 meters, with an area of 0.192 square meters and a diagonal of about 0.625 meters (62.5 cm).

Applications of a 40x48 size vary by context. It is a common dimension for large-format prints, posters, and gallery mats or frames in some markets. In other contexts, the same numeric pair may refer to dimensions in centimeters or millimeters for architectural drawings, signage, or display panels. Because the units are not explicit in the notation, users should verify the scale and orientation when ordering, mounting, or comparing sizes across different measurement systems.
