What are the common widths of racks?

Explanation:
Racks use standardized mounting widths, with one width being the norm for most IT equipment. The typical front-mounting rails and equipment are designed for 19 inches. That makes 19 inches the standard width you’ll see in the vast majority of racks and patch panels. A wider option, about 23 inches, appears in some telecom and certain wall-mounted or specialty cabinets. This wider external frame accommodates the additional doors and clearance those setups require, while the internal mounting rails still follow the 19-inch pattern. So the common widths to expect are 19 inches and 23 inches. The other widths listed aren’t standard for most rack mounting, and 24 inches is generally referenced as depth rather than width.
