When drying lumber, how wide and how thick should the stickers be, and how far apart?
If you are stickering 1 inch or thinner boards, go 12 to 16 inches apart; closer for real thin boards. If you're stickering framing lumber you can spread them out to 16 to 18 inches, and even a little more if you're doing beams. I never go wider than 20 to 24 inches.
Although 16 to 18 inches is very good for expensive hardwoods, just about every commercial operation uses 24-inch spacing. I wish it were closer.
Also, very few operations add weights to the top of the pile -- 10 inches of concrete over the entire top would make for very flat lumber. Any weight is better than none!

The weight does indent slightly, but that is why most people use 3/4 x 1-1/4 (or even 1-1/2) wide sitckers -- to help disperse the weight.
