Why are racks 19 inches?

When it comes to designing and building electronic equipment, one of the most common standards that is followed is the 19-inch rack size. But have you ever stopped to wonder why racks are specifically 19 inches wide? In this blog post, we'll explore the history and significance of the 19-inch rack size and why it has become the industry standard.

The 19-inch rack size has been around for over a century and has its origins in the telecommunication industry. In the early days of telecommunication equipment, there was a need for standardized rack sizes to accommodate the various components of telephone systems. Engineers at the time settled on a width of 19 inches as it was deemed to be a practical and manageable size for housing the equipment.

The 19-inch rack size quickly gained popularity and became the de facto standard for other industries as well. Today, you'll find 19-inch racks used in a wide range of applications, from server rooms and data centers to audio and video production studios.

So why exactly are racks 19 inches wide? One of the main reasons is compatibility. By sticking to a standardized rack size, manufacturers can ensure that their equipment will fit into any standard 19-inch rack. This makes it easier for customers to mix and match components from different manufacturers without having to worry about compatibility issues.

Another reason for the 19-inch rack size is efficiency. The width of 19 inches provides a good balance between space utilization and accessibility. It allows for easy access to equipment for maintenance and installation, while also maximizing the use of space in server rooms and data centers.

In addition to compatibility and efficiency, the 19-inch rack size also offers some other benefits. The standardized size makes it easier for engineers and technicians to design and build equipment, as they can follow a set of guidelines and specifications. It also helps to streamline the production process, as manufacturers can mass-produce components that are compatible with 19-inch racks.

But why specifically 19 inches? The answer lies in the imperial system of measurement. In the early days of the telecommunication industry, when the 19-inch rack size was first established, the United States was using the imperial system of measurement. The 19-inch width was likely chosen as it was a convenient size in the imperial system and provided a good balance between space utilization and accessibility.

While the 19-inch rack size has its roots in the telecommunication industry, it has since become a global standard that is used across various industries. Whether you're setting up a server room, a data center, or an audio production studio, chances are you'll be working with equipment that is designed to fit into a 19-inch rack.

In conclusion, the 19-inch rack size has become the industry standard for a reason. It offers compatibility, efficiency, and ease of use, making it a practical and convenient choice for housing electronic equipment. So the next time you're setting up a rack system, remember that there's a century-old history behind the 19-inch rack size – and it's here to stay.
