The standard is and the thing do is to say whatever it takes to sell the printer.
If you ask the marketing department build area will be the bed plate size even though very few printers can really print from edge to edge. Actual build area is hard to predict because it is a function of flatness, leveling, temperature, and size as well as the limits of motion of the extruder/bed. If the bed is heated the temperature will drop near the edges and corners and plastic may not stick reliably. If the bed is 300 x300 but the heater stuck to the bottom is 200 x 200, you won't be able to print much larger than 200 x 200 (for materials that require a heated bed).
The marketing people will tell you the printer's resolution is the mathematical result of the microstepping/by the pulley circumference, even if the frame wobbles and shakes while the printer runs and the thing produces terrible Z aritfacts.
They'll say the machine is "ABS compatible" if the hot end can get hot enough to melt ABS even if the bed can't get hot enough for it to stick and the machine has an open frame.
They'll say the Z axis resolution is 20 um even if the bed isn't flat enough to allow such fine layers over more than the central few cm^2.

How about printing a big cube and seeing how big the printer can actually print? That would be a powerful sales tool (assuming the cube was actually big). I think I saw something like that in a recent Prusa video.
