The diameter of Mars is just over half the diameter of Earth.
To be accurate, it depends on where you measure it.
The equatorial radius of Mars is 3,396.2 km which is 0.533 Earth's 6,378.1 km.
The polar radius of Mars is 3,376.2 km which is 0.531 Earth's 6,356.8 km.
From smallest (1) to largest (8) 1. Mercury. Diameter (at the equator) = 4880km or 0.3825 x Earths diameter 2. Mars. Diameter = 6794km or 0.5323 x Earths 3. Venus. Diameter = 12104km or 0.9488 x Earths 4. Earth. Diameter = 12756km 5. Neptune. Diameter = 49,532km or 3.88 x Earths 6. Uranus. Diameter = 51,114km or 4.01 x Earths 7. Saturn. Diameter = 120,534km or 9.45 x Earths 8. Jupiter. Diameter = 142,984km or 11.21 x Earths
Pluto (if you still count it)- (diameter - 2300 km) Mercury - (diameter - 4879.4 km) Mars - (diameter - 6787 km) Venus - (diameter - 12,104 km) Earth - (diameter - 12,115 km) Neptune- (diameter - 49,528 km) Uranus - (diameter - 51,118 km) Saturn - (diameter - 120,660 km) Jupiter - (diameter - 142,800 km) But Venus is the about the same size as Earth, its a little bigger not by much though.
Earth is larger than Mars in terms of both diameter and mass. Earth has a diameter of about 12,742 kilometers, while Mars has a diameter of about 6,779 kilometers, making Earth about 1.9 times larger than Mars. Earth's mass is also greater than Mars', with Earth being about 10 times more massive than Mars.
Mars is the second smallest planet, Mercury is the smallest. So out of the eight planets, it is comparitively small. Mars' diameter is about half that of Earths. The Gas giant planets are much larger than the inner planets, so these would dwarf the planet Mars (and Earth).
The diameter of the Earth is about 7,926 miles (12,756 km). The diameter of Mars is about 4,222 miles (6790 km) - roughly half that of Earth.
Mars is bigger than Earth's moon. Mars has a diameter of about 4,212 miles, while Earth's moon has a diameter of about 2,159 miles.
110 times greater..
The Sun's diameter is about 109 times the Earth's diameter.
Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12104km or 0.9488 x Earths Earth's diameter = 12756km Mars' diameter = 6794km or 0.5323 x Earths The inner planets are all much smaller than the outer gas planets; Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths
Mars is only about half the diameter of Earth.

The warmest places on Mars are about the same temperature as the coldest places on Earth.
