Insufficient information for a meaningful response.

Try one of the online joist span calculators, such as the Canadian Wood
Council's, and provide the missing information. It will tell you the
allowable span based on deflection and wood species.

Your municipal building permit office can tell you.

it depends on the span and the requirements in your local area.
some build a second floor deck with less, but ours is 8x8" posts, so
overbuilding is good here in this case since the deck overlooks a
cliff.

OP-

Joist depth needed is a function of span & spacing; check your local
code, check out some span calcuators on the web My 1930's hosue has
2x6 but they're supported every 4ft

also for long spans, to avoid winding up with a bouncy floor I would
suggest either reading & understanding

Canadian Building Digest
CBD-173. Floor Vibration

http://irc.nrc-cnrc.gc.ca/pubs/cbd/cbd173_e.html

This is some very good work into the behavior of floor vibration

OR

short of doing the calcs (or having someone do them for you) I'd just
bump up to the next joist depth. I'd also consider engineered ood
joist for longer spans (again going deeper)

wood is cheap, problems are expensive

Depends upon if you are using structural wall paper
