How would the size of a parachute required to safely land a space probe differ on the planet Mars?

A parachute that would function on Mars would have to be very large, much larger than one used in Earth's atmosphere, because the atmospheric pressure on Mars is much lower. The surface pressure is only about 600 pascals, about 1/160th the sea level pressure on Earth. The thinner the atmosphere, the less force exerted against the parachute as it slows a falling craft.
Some Mars probes are designed to use retro-rockets and inflatable cushioning bags, to supplement their parachutes.

How would the size of parachute required on a space probe to allow it to land safely on a planet such as venus which has a thick atmosphere?
It would need to have a small parachute for a planet such as venus, because the atmospheric pressure is about 90 times that on Earth. This increases air resistance (drag) slowing the probe down. Therefore, the small parachute allows the probe to have more acceleration.
