Canine Wolf Vs Dog Breed?

Ok i know theres allot of breeds, like english mastiff, bullmastiff, dogo argentino, american bulldog and allot more that can kill a wolf, but now, which dog is taller. I think wolfs are no bigger then german shepherds, right? German shepherds stand 24 - 26 inches and weigt 75 - 140 pounds. But now i know for sure english mastiffs, irish wolfhounds, and great danes have to be taller, please let me know if im right. I know that the tallest is irish wolfhound then borzoi and another breed then great dane then english mastiffs, i also know that 60 % of english mastiffs get bigger then danes height whise, and ALWAYS weight whise, cuz there the heaviest dog breed, but thats besides the point. HOW TALL DOES A MATURE GREY WOLF GET?
