What does this mean? For electronic equipment racks (e.g., 19 or 23 inches wide), the term 1U is used to define one rack unit of height. To be precise, 1U equals 1.75-inches (44.45mm) of rack height. Therefore, a 2U rack mount height would be 2 x 1.75”, which equals 3.5-inches high.

What size is 1U?

1.75 inches
1U refers to a height of 1.75 inches or 4.445 cm. This is the space between the rack shelves that is available for device installation. The size of rack mountable devices is often specified in ‘U’ with a number. A one-rack device is a 1U, while a 2U device requires two rack units.
