The answer to this question is too complex to describe here. There are too many factors which are not specified in the question, such as load in pounds per linear foot, spacing of the 4X12 joists, as well as grade and species of lumber.

What size of beam do you need to span 18 ft?
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.
On a deck what would be the maximum spacing of 2'X12' floor joists on a 20ft span?
Even using a 2x12 the spacing for 20 feet will be less than 12 inches on center. I would recommend splitting the distance with a double beam perpendicular to the joist run. This will allow you to go up to 24 inches on center. Your span will only be ten feet aproximately this way. I would double the beam. (2-2x12 joined together) Good luck. when building your beam make sure the laps on the beam are at least 6 foot apart and put a good wood glue on the 2x12s plus for added strength put 1/2 inch O.S.B. in between the 2x12 and I would also lag or bolt them together, at about 16 to 24 inches O.S.B. = Oscilating Strand Board.
Can a 4X8 beam support a floor with a span of 13 feet?
Technically Yes, but you'll need to check with your building inspector because there are codes regarding structure that vary from place to place, and the inspector isn't going to pass something based on my say so.The old rule of thumb was 1 inch for 1 foot, so a 12 foot span would require a 2 x 12.A 4 x 8 isn't equal to a 2 X 16, or even 2 2 X 8's, but it should do if the load isn't too great.I'm guessing you want to go with 8" stock because you've got some headroom issues. You'd be better off structurally with an LVL (Laminated Veneer Lumber) or OSB (Oriented strand Beam) or a truss, but these are kind of pricey.If you get in trouble see if they'll let you go with them on 12" centers.
Will a 6 x 12 wood beam span 12'?
Only if it is at least 12' long.
How much weight can a 2 x 12 beam hold span of 10 feet?
It depends on what the beam is made of.
How far can you span a 12 steel you-Beam without a support?
Depends on the loads and the properties of the beam. Consult a structural engineer.

What thumb rules do you follow while assigning the size of a beam in RCC design of structures?
depth of a beam can be approximately calculated as follows span/12 and breadth=depthX(1/2 to 2/3)
What size spruce beam header would you need to span 12 feet while supporting the center of a truss roof?
You must also take in consideration the width of the building. For instance a 12'x16' building you would use 2x6 rafters and a 2x8 beam with collar ties every 4'.
