The total surface area of Jupiter is approximately 23.7 billion square miles, or 61 billion square kilometers. This is 120 times greater than the surface area of Earth.
Jupiter is the largest planet in the solar system, with an average radius of 43,440 miles. Its total volume is approximately 3.4 x 10^14 cubic miles. More than 1,300 planets the size of Earth could fit inside of Jupiter.
Because Jupiter rotates very quickly, the planet is flattened at its poles. At the equator, its diameter is nearly 89,000 miles, but from pole to pole, the diameter is only 83,000 miles. The circumference at its equator is nearly 273,000 miles.
