Over time, most treated lumber will shrink slightly across its width as it dries out. Take this small amount of shrinkage into account when laying decking or fence boards.
How much does pine shrink when drying?
As wood loses moisture content, it will also shrink in size. In fact, as wood dries below about 30% moisture content, it will lose about 1% in the radial and tangential directions for every 4% drop in moisture content. Wood shrinks very little in the longitudinal (lengthwise) direction as it dries.
