joist span for 8' x 10' deck
I'm looking to build a small attached deck off the house, 8' deep and 10' wide. Deck planks will be 2x6 redwood running parallel to the house. I was originally planning to use 2x6 pressure treated joists for the 8' span, 16" oc, supported at the house and at halfway & end with piers.
However, the deck is only about 10" off the ground and I'm concerned about airflow. Can I use 4x6 pressure treated at 32" oc instead? Will the 32" (true ~ 29") oc give way too much bounce for the planking, even with the stronger joists?
