This is in Austin, TX, USA. Photos taken at night on a phone with a flash, so colors may not be entirely accurate.
I found this spider hiding inside my motorcycle cover, which I'd thrown in a pile on my front porch for a few days.
It wasn't aggressive nor skittish, although it did scuttle away at a relatively slow pace as soon as I tried to move it using a large envelope. I would estimate its diameter (legs included) at about 1-1/2 to 2 inches (38mm - 51mm).
I was very cautious around it since I thought it might be a brown recluse, but I know there are a number of Central Texas spiders that bear a resemblance. I couldn't make out the "violin" on its back but I also didn't get close enough to make sure.
