Can one lung be larger than the other one?

Does anyone know if one lung is usually larger then the other one? My one lung is larger and I don't know if this is a concern or not. I have heard that kidneys aren't the same size, but was wondering about the lungs? It's my left one that is larger and since I have pain on that side, I am concerned since I saw the chest X-ray report about it being larger then the right one.
