A crow has blunt and opened wings, and their wingspan is about 32 to 40 inches. Ravens have pointed wings, and their wingspan is 46 to 54 inches. The feathers of a crow are less glossy, and they may have lighter markings. A raven's feathers taper off at the end and form a wedge. A crow, on the other hand, has a fan-shaped tail.
A raven is twice the size of a crow. The size of a crow is 17 inches long, and it generally weighs around 20 oz. The raven's size is about 24 to 27 inches long, and it weighs approximately 40 oz. Ravens have a much larger head than a crow with a long, curved bill. Also, crows usually flock with other birds, while raven's like to fly either solo or with one other bird.
