Which gauge is thicker?

Which gauge is thicker?

• A. No. 6 gauge
• B. No. 8 gauge
• C. No. 4 gauge
• D. No. 2 gauge

Answer: (C)

In this gauge system, thickness goes down as the gauge number goes up. In other words, a lower gauge number means a thicker piece of metal. So the order from thickest to thinnest among these options is: No. 2 gauge, then No. 4 gauge, then No. 6 gauge, then No. 8 gauge. Therefore the thickest among the four is No. 2 gauge. The provided answer identifies No. 4 as thicker than 6 and 8, which is true relative to those two, but it is not the thickest overall. The key idea to remember is that gauge numbers decrease as thickness increases.
