For this reason, this post focuses on server rack dimensions.

Standards server rack dimensions

One of the primary defining characteristics of server racks is the dimensions. Below are standard server rack dimensions:

1. Height

The heigh is one of the popular elements used to classify servers and server racks. More often than not, server rack manufacturers label their products based on their specific height.

For instance, a manufacturer may name their product “the 42U server rack.” In this case, the U stands for rack units. It can also be expressed as U-spaces. Each of the spaces usually features a standard 1.75 inches.

Therefore the size of the rack is calculated by multiplying the number of rack units by 1.75 inches. The average standard height of a server rack is 7 feet or 42 unit racks. Server racks with these dimensions are ideal because they can accommodate various IT equipment and accessories. They also allow room for airflow and cabling systems. However, note that the height may differ from one manufacturer and application to the next.

2. Depth

The server rack depth is not measured in rack units. It is measured in inches. Unlike the height, the server rack depth typically features fewer size variations. This means that server racks can range between zero to fifty inches in depth. However, most server racks on the market are labeled at twenty-four and forty-eight inches in depth. Twenty-four-inch server racks are an idea for housing network and AV equipment. They are also perfect for storing patch panels and other small equipment.

On the other hand, forty-eight-inch server racks are suitable for larger equipment that need more storage space. Some racks allow for depth adjustments. This can be done by moving the mounting rails. Note that the depth is usually determined by the intended application of the server rack.

3. Width

The standard width for most server racks is nineteen inches. The width is typically measured from one hole to the next. This means that a server rack may have a larger overall or exterior width and a smaller hole-to-hole width. Nineteen inches is the standard size as it can fit the standard size of IT equipment. There are also server racks with a width of twenty-four inches. Manufacturers create such server racks to provide more storage space and added room for ventilation.


Note that the server rack dimensions may differ from one brand and server rack to the next. For instance, wall-mounted server racks are typically smaller than the latter. The type of application intended for the server rack also determines the size.
