I'm not sure how I came across this picture by a photographer named Garret Lau, but I always thought it showed demonstrably the difference between a crow and a raven. The American Crow (Corvus brachyrhynchos) is 17.5" (45 cm) long, while the Common Raven (Corvus corax) is almost 6 inches longer than the crow at 24" (61 cm). The crow also has a smaller bill than the raven. Both birds are found in a variety of habitats, but the raven is found farther north and west in North America (including the arctic), but not in the southeast of the United States. The crow is found throughout the U.S.A. and the lower half of Canada.
