Just like modern animal, biggest dinosaurs belong to herbivorous group. In our world Animal like Elephant, Giraffe, Rhino, Hippo are the biggest, heaviest and longest animal and all are herbivorous.

Biggest dinosaurs are sauropods. By far the largest creatures ever to roam the earth, sauropods branched into numerous genera and species over the course of 100 million years, and their remains have been dug up on every continent.
From my sources, The biggest verified dinosaurs is Argentinosaurus. The size of Argentinosaurus has been supported by convincing evidence. In 1986 the remains of this gigantic titanosaur was discovered in Argentina (and hence the name).

According to paleontologists Argentinosaurus could have weight 100 tons and over 120 feet long from head to tail.
Other contender are Amphicoelias fragilis, Bruthathkayosaurus, Futalognkosaurus and Brachiosaurus.

 Amphicoelias fragilis said to be longest and may be heaviest dinosaurs of all time, Source claim that it was 200 feet long and almost 125 tons heavy.
This dinosaur is represented in the fossil record by a single vertebra measuring 5 by 9 feet long, truly enormous proportions that correspond to a sauropod measuring about 200 feet from head to tail and weighing over 125 tons.
But Not everyone is convinced, especially since we no longer have that backbone to examine. So I don't think it should be considered as biggest dinosaurs

Bruthathkayosaurus found in woodland of India is said to weight about 200 tons and 150 feet long. But once again not enough evidence to support it.
Pieces of Bruthathkayosaurus that have been identified so far don't convincingly  support to a titanosaur

Futalognkosaurus is also of huge size nearly 100 feet long and 75 tons heavy. Good thing about this dinosaurs is that about 70 percent of skeleton has been recovered which is more than any  titanosaur.

There are many more contender in this category and I am sure many of other will emerge in future.

Next we will discuss about Giant theropods (Meat eating). Like Spinosaurus, Tyrannosaurus Rex and  Giganotosaurus

This might be like "not dinosaur" but there are animal that are larger than dinosaurs which is Megalodon. Megalodon was also far bigger than the great white shark, which would only be around half of Megalodon's size. Megalodon has also been found to be far larger than the gigantic theropod dinosaurs such as Spinosaurus, T-Rex, as well as the large ocean going marine reptiles such as Basilosaurus, and Tylosaurus.
