285mm

285 millimeters (mm) is a unit of length in the metric system. It equals 0.285 meters and approximately 11.22 inches.

Millimeters are used to specify precise dimensions in science, engineering, manufacturing, and construction. A dimension of 285 mm can denote the width of a sheet or plate, the overall dimension of a housing, the spacing between holes, or other component sizes in technical drawings and specifications.

285 mm is not a named standard size in widely used systems such as ISO paper formats or common display sizes. It may appear as a design or tolerance requirement in engineering projects and can be chosen to fit a particular part or assembly.

Because it lies between common metric and imperial sizes, 285 mm is easy to communicate in both measurement systems, aiding cross-border collaboration in technical domains.
