How do you designate the size of a bench vise?

Thickness of the jaws
Length of the vice
Width of jaws
Height of the base

The correct answer is: Width of jaws

The size of a bench vise is typically designated by the width of the jaws. This measurement is critical because it directly relates to the maximum size of the workpiece that can be held securely in the vise. A wider jaw allows for more versatility in clamping larger materials, making it an essential specification for users to consider when selecting a vise for their specific tasks. While other attributes like the thickness of the jaws, length of the vice, or height of the base may provide additional information about the vise's capabilities or dimensions, they do not serve as the primary metric for size designation. Instead, the width of the jaws is the standardized measurement that indicates the vise’s capacity for holding material effectively during machining or assembly processes.
