The gauge system for wire indicates the wire’s diameter, with a higher gauge number corresponding to a smaller diameter. Wire gauges are typically defined by the American Wire Gauge (AWG) standard. In this system, #16 gauge wire has a specific thickness, and as the gauge number increases, the wire becomes finer.

In this context, #20 wire is finer than #16 wire because it has a higher gauge number. Specifically, the diameter decreases as the gauge increases, meaning that #20 is smaller and therefore finer than #16. The finer wire is often used for delicate arrangements or small projects where a lighter touch is required.

The other options, such as #14, #18, and even #22, demonstrate thicker wire compared to #20. As you move to lower gauge numbers, the wire diameter increases. Thus, #14 is more substantial than #16, #18 is also thicker than #16, and while #22 is finer than #20, it is not the answer to this specific comparison with #16. Hence, #20 wire being finer directly aligns with the definitions of the gauge system.
