Depends what you mean by 'largest'. There were some very tall dinosaurs (I believe that a brachiosaur is still the tallest from ground to top of head). There were some very long dinosaurs (I'm not sure who ranks as the longest now; at one time it was a diplodocid). And there were some very big and heavy dinosaurs (I really don't know who's the tops any more). Of course, all of these dinosaurs were sauropods, so you could safely go with that.
As for smallest, it's hard to know - Compsognathus is certainly very small, but with all the new discoveries in China, I'm not sure whether something even littler has been discovered.

Hey. Currently the largest (longest) dinosaur is Seismosaurus at 150 feet; (heaviest) dinosaur is Argentinasaurus ranging in at around 50 tones. The smallest dinosaur (size and weight) is currently Mussaurus, being about the size of a rat. (Of course, the more avian dinosaurs [Archeaopteryx, Mircroraptor etc.] were perhaps smaller, about the size of a crow or sparrow respectively. Hope this helps. P.S. Seismosaurus and Argentinasaurus are both longer and heavier than a blue whale.
