"Gauge" is the thickness of the fence wire, similar to the "gauge" of electric wire or tennis racquet string. "Gauge" represents the number of strands of a single given width that can fit in a standard measure tube. For example, if I cut a length of wire into 5 pieces of a foot long each, and they all fit perfectly into that tube, then you could say that it is "5 gauge" wire. If I take a thicker wire, and cut it the same way, but only 4 pieces fit perfectly in the tube, then it is "4 gauge" wire. Thus, the thicker the wire, the lower the gauge (i.e., less can fit into the tube), and the thinner the wire, the higher the gauge (i.e., more can fit into the tube). Again, the same is true for electric wire and tennis racquet string, et al. Given the common gauges of chain link fence, this product's 12.5 gauge metal wire is THINNER than another chain link's 11.5 gauge metal wire. If you're wondering which is "better," it depends on its intended use. If it's to keep dogs and children in (or out), then you might want to go with the thicker gauge (11.5). But, if it's meant to keep critters from gobbling your garden goods, then the thinner gauge (12.5) would probably suffice. Generally speaking, the thicker gauge wire is more expensive than the thinner gauge, which makes sense, since you're getting more product, but, again, it depends on its intended function, so, saving a few bucks might cost you in the long run!
