Pressure Treated Shrinkage

I'm expanding a deck that I built 2 years ago and am curious if I should add 3/16" to 1/4" to the cuts that would affect height so that after shrinkage everything will still line up. I could also let the wood dry first but it seems like this would take a long time.

Thoughts?

Boards shrink along their width, not their length. So if you are talking the width of your joists, you would have to measure the existing ones and the new ones. My guess is that 1/8" would be plenty.

I'm talking about the height of the posts, and the 11.25" dimension on the 2x12 beam.

Height of post, no difference. If the new joists are already 11.25 they won't shrink much at all. No more than 1/8. I wouldn't worry about it at all.
