What is the maximum length of a USB cable?

The maximum length of a USB cable, specifically for USB 2.0, is 5 meters (approximately 16.4 feet). This length ensures reliable data transmission and minimizes potential signal degradation that can occur over longer distances. Beyond this length, the USB signal may weaken, leading to a higher chance of data loss or connection issues.

For USB 3.0 and subsequent versions, the maximum length is generally less than that of USB 2.0, approximately around 3 meters, due to the higher data transfer speeds which are more susceptible to interference over longer distances. Hence, while other choices reflect either shorter distances or greater lengths that exceed the specifications for conventional USB cables, 5 meters is recognized as the standard maximum length for maintaining optimal performance and connectivity with USB 2.0 devices.
