What is the thickness of 22 gauge in inches?

Explanation:
Gauge thickness is listed as an inverse scale: as the gauge number goes up, the metal gets thinner. For common steel, 22 gauge is about 0.0299 inches, which is very close to 1/32 inch (0.03125 in). Among the options, 1/32 inch best matches the typical 22 gauge thickness, so it’s the correct choice. The other options are notably thicker or thinner than that standard value (1/64 is much thinner; 1/16 and 3/32 are thicker).
