I think this is the right place to ask this?

Anyway, I'm planning on building a lawn shed for our lawn stuff... probably 8x8 or 8x12 or abouts ... my question is.. would you make the walls 16 in centers or 24 in centers?

I'm thinking this small of a shed, 24's would work but the small cost of making them 16's would make it a lot more sturdy at just a bit more cost.... or would it matter??

I'll be using 2x6's for floors and 2x4's for walls....

Thanks for any input....
