I assume you're making returns, and I believe you're looking for the word "PERIMETER" - the total distance around a geometric shape...or, in this case, a letter.
A CAD program like AutoCAD will give you the perimeter (and area) of grouped objects, and if they're un-grouped it will give you lengths of specific segments such as lines and arcs.
Not sure about other programs...most will give you line segment length, but I don't know about arcs and beziers.
