About four inches (10 centimeters). Velociraptor, meaning "swift robber"
a t-rex's claw was about a gazillion feet long
about 2 inches long
There were many different species of raptors, and larger ones had larger sickle claws. Velociraptor was 6 feet long and had a claw that was 2.6 inches long on the outside edge. Utahraptor was 23 feet long and had a claw that was 9.4 inches long.
Iguanodon doesn't have a long claw on each foot. They do have a long claw on each thumb, which they may have used for defense. Dinosaurs that do have a long claw on each foot are dromaeosaurs, such as Velociraptor and Troodon, and they used these long, curved claws for hunting by stabbing and slashing their prey in soft areas with blood vessels.
