BIG, UGLY Spider outside my front door. What type?

[ph4nt]

Orb Weavers come in lots of different colors. Here is another one that looks more like your picture

Same thickness of legs, same back shap, same hairs on the legs. I think that's what you got, they aren't harmful to humans.

 

There are over 2700 species of this type, So i'm sure yours is one of them.
