There are so many spiders of different kinds in Ohio that it would take an entire book to discuss them. There is a book about the Spiders of Connecticut, and it is over an inch thick.
The spiders in Ohio are about the same group as the ones in Connecticut. Generally speaking, in Ohio you could probably find some member of every genus of spider that is found in the U.S. with the exception of the kinds that are limited to the hottest areas of this country such as Florida and the states the border the Gulf of Mexico. That means that you won't find any tarantulas in the wild, nor will you find Huntsman spiders, golden-silk orb weavers, and maybe a few other of the main Families of spiders. The reason is generally going to be that it is too cold in Ohio for some spiders to survive.
There are some kinds of spiders that are found in other parts of the world, but not in the United States. The oceans have kept Eurasian and African species at home. There are also spiders in Australia and New Zealand that are unique to those areas.
I am pretty certain that is a variety of the wolf spider. scary as all hell, but completely harmless.
Ohio is Very Far Away

Sounds like a tarantula.

My guess is that this spider you saw was either a Jumping Spider (quite possibly a Daring Jumping Spider) or a Parson Spider.
It is called a Cotton Spider. I dont know if they are dangerous but I doubt it. They have never bothered me and I am really afraid of almost all spiders. However, Living in Oklahoma you tend to get more used to them and just kill as many as possible.
A big,hairy European spider with a painful bite is what we call the ''TARANTULA''
