It is usually 16 inch.
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.
16" 19.2" and 24" are the standards, because they will all divide evenly into a sheet of plywood deck mr graf is always wrong
Not really. All joists will be the same whether you are working on a 1st or second floor, so your floor does not have a bunch of different levels. Usually we use 2 x 12 lumber, doubling joists which have walls above them or decreasing the spacing if you are at the limits of the span. example you have a 22' span in a garage with living area above it, you would use 2 x 12 with 12" on center spacing.
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.
