Hoods cover the head, can be attached or detached (university graduation hoods). It can also be a garment of it's own usually about chest length like the one Robin Hood wore. Hoods can have many names e.g. liripipe.
A cape is usually circular, can be ovoid, square (poncho) and begin to be called cape from waist-length to sweeping-the floor length. Shorter lengths are called capelets or mantelets and can be with or without hoods. Long-ish hooded capes are called cloaks.
After looking at too many pictures, it seems that the term cape and cloak are interchangeable. Then again......cloaks and robes.......yeah...headache....a Jedi cloak or robe? A Harry Potter cloak or robe?
Whatever they are, I hope these vintage pictures below (no more copyrights applicable) will give you an idea of the style or garment you wish to make.
