The smallest dinosaur known is the Parvicursor remotus, which was ony 12 to 15 inches long and is estimated to have weighed 4.8 and 5.7 ounces. Parvicursor was a tiny, bipedal feathered theropod dinosaur. It was an Alvarezsaurid, so it only had a single finger, with a claw. It may have used that claw to dig into termite mounds. To escape predators, they would have run quite fast.
So far, the records are these:

Smallest dimensions
Most palaeontologists believe compsognathus was the smallest dinosaur, but recent discoveries of an a dinosaur, micropachycephalosaurus that may be the smallest dinosaur ever and has the longest name ever given to a dinosaur!The smallest dinosaur is said to be the compsognathus.Its just 2 feet long and weighs only up to 6.5 pounds. There are a few more small dinosaurs which have the same heeight of the compsognathus.They are the saltopus and the echinodon.
The smallest adult fossil of a herbivorous dinosaur belongs to Echinodon becklesii.
The smallest unit of life is known as an atom!
compsognathus is the smallest dinosaur and is the size of a chicken, but palaeontologists have just discovered 'micropachycephalosaurus' which might be even smaller and has the longest name of any dinosaur so far!

Epidexipteryx is the smallest known dinosaur. It weighed only 0.36 lb.
At only 25 centimeters long, Epidexipteryx is the smallest-known non-avian dinosaur. Its tail feathers are not counted in its official length.
Epidexipteryx is the smallest known dinosaur. It was a feathered theropod less than 10 inches long and weighing about 0.36 lb.
The smallest known dinosaur is Epidexipteryx, and it weighed only 0.36 lb. The largest known dinosaur with well preserved remains was Argentinosaurus, which weighed up to 80 tons.
the biggest dinosaur was amphicoealis fragillimimus and the smallest dinosaur microraptor or frutaidens
The smallest dinosaur is Microraptor, probably less than 1 ft tall, and is 2 ft long.
Compsognathus was once thought to be the smallest known dinosaur. However, smaller dinosaurs have since been discovered, such as Epidexipteryx.
The bee hummingbird (Mellisuga helenae) is "the smallest dinosaur that ever lived". Of course your question only applies to non-avian dinosaurs. For over a century the smallest known dinosaur was the 3 foot Compsognathus, otfen compared to chickens in size. The discoveries in China for the last 20 years have revealed many smaller dinosaurs. Currently the smallest known dinosaur is Epidexipteyx, at only 1 foot long. The smallest dinosaur that ever lived on earth was "westlothiana," it is almost the same size as a fully grown human's toe!
The smallest dinosaur is a humming bird.
The smallest dinosaurs were just slightly larger than a chicken; Compsognathus ("pretty jaw") was 1 m (3 ft) long and probably weighed about 2.5 kg (about 6.5 lb). They lived during the Jurassic Period. Mussaurus ("mouse lizard") was claimed as the smallest dinosaur, but it is now known to be the hatchling of a dinosaur type that was much larger than Compsognathus when fully grown. If birds are advanced dinosaurs, then the smallest dinosaur today would be the hummingbird!
