all floor joist tables start with 2x6 lumber. if you use awc calculator 2x4 can span 6'2' with l360 deflection for decks 40lb ll. i personally think it will be a bouncy floor. shorten the span maybe to 5' and put them 12' oc or like mac said 4'- 16' oc.
the appropriate spans for deck beams and joists are determined in part by the weight loads that the deck will have to bear. the so-called dead load is the weight of the deck structure itself
the distance your joists can safely cantilever or overhang a drop beam is determined by the size of the joists, the wood type and grade of the lumber and the spacing between joists. many building departments limit joist cantilevers to 24' maximum. you must use at least five framing nails to attach the rim joist to the ends of your joists.

if you are allowed to use 2x4's for the joists, it'll cost you more money than using 2x6's would. the 2x4's won't span as far, so you would need more beams and more footings to support them. and your math on the beam spacing isn't adding up. 3 beams spaced 5' apart total 10'. add 2' of overhang on each side and that makes the deck 14', not
low profile deck using 2x4 joists by: editor - rich bergman 2x4 joists would be sufficient depending on close they are spaced no further than 12' on center, maybe even a bit closer and how long the 2x4s will span from one support beam to the next. 2x4s can not span a very long distance without starting to bend.
deck joist sizing and spacing. the layout term for joists is “on center,” which is the center-to-center measurement from one joist to the next. most decks use 16' on center spacing for joists. most decking is not strong enough to support longer spans than 16'. some builders reduce joist spacing to 12' on center to strengthen the deck
these shallow waters are guarded by currents, so no hagfish appear. the waterfront has three docks; meagan's parked on the easternmost. steal a pouch from the workbench-using npc, then hop into the water nearby to find a medium-sized shipwreck. its submerged deck holds an ivory scrimshaw and some small change worth 10 coins.
