osb floor thickness

HELP!!! I'm building a loft in my barn approx. 6 ft off the ground. The loft is supported by a 4x8 treated pole in each corner (12x12 ft) with 2x6 beams from joist hangars running 18in. apart. I just don't know if I got the right thickness OSB. Is 7/16" thick enough or should I go get 3/4" ???

Now, I realize this whole thing is not up to code and we expect it to be springy... but is the 7/16" OSB strong enough for joists spaced so far apart???

OSB subfloor

I'd go with the 3/4" OSB.

I also would use 3/4, but then I wouldn't have used 2x6s spanning 12' either......so don't plan to put much of any weight on that floor.....like almost none......
