Racks have traditionally come in 19, 23 and 24 inch mounting widths. Today, the 19 inch is the standard for most applications, including A/V systems. All Middle Atlantic A/V racks have 19 inch wide rackmounts. The 19 inch mount is just the internal mounting width from rail to rail. Overall width depends on the kind of rack. For bigger heavy-duty rack enclosures that will need a thick steel frame to hold larger, heavier equipment, or to run cabling down the side you can expect the overall width to be around 22-23 inches or more. For a simple system with 4 or 5 consumer electronic components, you may need a smaller, slimmer rack with as little as 19.125 inches of width. Remember that the width of the mounting shelf or rack ears on the piece of equipment that you are mounting have to be compatible with 19 inch wide rackmounts.
