I'm not sure how big my wood shed is, probably like 14x18 and it's completely full, stacked 8 feet high all the way through, and has a couple ricks across the end not covered. Last year it took about 1/2 of the shed full, I'd say I have well over 2 years of wood cut.
About 40% of my wood is well seasoned and it will be burnt this winter, however i'm excited about next years wood, there was a HUGGGEEEEE double white oak that fell in my grandparents back yard. The logs were over waist high, and absolutely full of huge limbs, we cut over 15 full size 8 foot truck bed loads of wood out of it. The rounds were so big it took 2-3 people to get them off the ground and rolled up on the splitter.
