Chicken wire has various gauges. Guage means the thickness of the wire and not the size of the hole. The lower the gauge, the thicker the wire. For example, 19 gauge wire, the wire could be approximately 1mm thick. Alternatively you could see 22 Gauge wire, which could be approximately 0.7mm thick.

The mesh size of hexagonal wire netting means hole size is from quite large at 22mm to very small at 5mm. Please choose the size depends on the animals you wish to keep in or out of an area. For example,if you want to keep rats and other rodents out of chicken runs you need to choose  approximately 5mm.

The chicken wire also comes in varying heights, we usually call this widths. The height required is depend on the size of animal .If you want to use 0.9m width,but you can only find hexagonal wire mesh like 1m.That you can cut down to the required width.
