What is a standard rack width in inches?

The standard rack width is 19 inches. This width comes from the widely adopted EIA-310 standard for rack-mount equipment, which defines the front panel width that equipment like servers, patch panels, and switches must fit into. Designing equipment to this 19-inch front width ensures compatibility across devices from many vendors, so they can all be mounted together in the same rack frame. The measurement refers to the width across the mounting rails where the devices’ front panels attach. While the overall cabinet or enclosure that houses the rack may be wider (and depth varies), the equipment itself is built to 19 inches. The other widths shown don’t align with the common rack-mount standard, so they’re not used for typical telecom or data-center rack gear.
