A 19-Inch Rack is the standard equipment rack whose mounting rails are spaced so that installed gear presents a 19-inch (482.6 mm) front panel width, with height measured in rack units. In data centers it is the dominant form factor for servers, switches and other IT hardware, standardized under EIA-310. Usable equipment width is 17.75 inches between the rails.
