Standard sizing for circuits feeding wall outlets is either 15A or 20A. In
commercial buildings (including offices), 20A is pretty standard. In
residential, for example, kitchen outlets above counter (for appliances)
are usually 20A. In most houses, if you run 12ga wire, the distances are
short enough that pretty much any circuit will handle 20A. Make sure you
get 20A rated outlets.

Under NEC it's acceptable to use standard 15A outlets on 20A circuits unless
it's dedicated to a single outlet. 20A outlets are really for cases where
you intend to use an appliance that REQUIRES a 20A outlet, as you will
notice they have an extra notch for the special plugs.
