You really should seek information on the _maximum_ distance between
supports. The minimum is always 0'-0" ;)

If you Google

wood beam span tables

you will get all the info you need, and more.

Maybe, maybe not. The span tables don't give you the load calculations
nor factor in all of the adjustment factors that apply to wood
structural members.

Dave-

If you can calculate the load that the beam will need to handle (lbs
per ft). you could use a span calculator to size it.

Depending on the load & the span you might be able to get away with a
multiple 2x10 or 2x12.

If the loads are high & you want to minimize beam depth you might
consider a glulam.

here is a link to glulam load / span tables depending on service
condition & wood species

And the key statement here is "Specific beam designs should be reviewed
by a licensed design professional."
