Rebar spacing

[Whitewheelin]

I'm looking to pour a slab soon and I was curious the spacing I should use for the rebar. I helped a guy pour one 2 years ago but I can't remember the spacing. I wanna say they were a foot squared when all the rebar was laid out. I'm wanting to Pour 24'x32' with a 4" floor and a club footing around the edges. Thanks Scott

A slab for...? Is it needed for code, or just over built like the was I do things? A little more info on the use of the slab and where you're located would help. If not needed to meet code, pretty much any spacing you'd like. I went with 18" with #3 bar in the slab and four #4 in the footing.

My 48' x 30' x 6" slab called for rebar according to the plans furnished with the building kit. It was 6" thick because I asked for that. The rebar was spaced at 12" square #4's.
