>>131376you're reading the post wrong and the sizes wrong. Adult wolf spiders measured from leg tip to leg tip are commonly up to 4 inches across easily. Their main body however is normally around 1 inches.
>There are many genera of wolf spider, ranging in body size from less than 1 to 30 millimetres (0.04 to 1.18 in).[1]The above is for the body, not the leg span.
Every so often you meet a freak that is a lot bigger like 5 inch leg span and 2 inch long body. They are the only large spider in this area. The second largest is the black and yellow garden spider.
The largest wolf spider I've ever found (in the late 1990s) was big enough to hang its feet over a tea saucer. I captured it after several attempts over the course of a couple days. It was scary as fuck too because I has to stand belly button deep in water and reach up to an over hanging tree to get it. Every time I missed it would drop to the water and skitter across the surface to the closest object (me) and I had to plunge underwater until it went to the tree roots. It was super fast on the water too.
