Distance of the holes in the row of holes: 32 mm; Diameter of the holes: 5 mm and 8 mm [clarification needed]. A typical 5 mm shelf stud may measure 15-16 mm long, and has a thin flange of about 7 mm diameter halfway at its length. Distance of the front row of holes to the front edge: 37 mm
Lateral files are typically 20 inches (510 mm) deep and manufactured in 30,-36,-and-42-inch (760, 910, and 1,070 mm) widths and 2-, 3-, 4-, and 5-drawer versions.

Rack with sample component sizes including an A/V half-rack unit. A rack unit (abbreviated U or RU) is a unit of measure defined as 1 + 3 ⁄ 4 inches (44.45 mm). [1] [2] It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed ...

This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
The size denotes the width of the faceplate for the installed equipment. The rack unit is a measure of vertical spacing and is common to both the 19 and 23-inch racks. Hole spacing is either on 1-inch (25 mm) centers (Western Electric standard), or the same as for 19-inch (482.6 mm) racks (0.625 in or 15.9 mm spacing).
