In desktop publishing this is often referred to as "baseline shift."
Usually it is expressed as a measurement in whatever units have been chosen
for typesetting units. With points chosen, a baseline shift of +3 would
place the character(s) above the baseline by three points, -2 below it by
two points.
This capability is frequently used for the trademark and registered symbols
and drop caps.

min | tiny | small | normal | large | huge | max
(Curiously, the number of characters in each name follows a bell curve.)
