The Hayden Sphere in front of you serves as a scale of reference for exploring this entire range of sizes.  For example, if the Hayden Sphere—26.5 meters (87 feet) in diameter—represents the size of the Sun, then Jupiter stretches 2.7 meters (9 feet) across, while Earth is a mere 24 centimeters (9.5 inches) in diameter.

Scale size measures
Major size scales of the universe include galaxies, stars, planets, humans, and atoms. We use a wide variety of units to measure each object at its natural size scale.

Scaling the universe: powers of 10
The complete range of size scales between the largest and smallest objects in the cosmos is truly astronomical. The observable universe is 100 million billion times bigger than a human, while humans are a million billion times larger than a proton in the nucleus of an atom.
