I'm not quite sure what you're asking. Are you asking if all worlds have the same density? They don't - Mars is larger than Mercury, but it has a lower density. Depending on how they were formed, two worlds could have the same radius, but different masses.Originally Posted by willstaruss22

Im just asking cause i asked if mars can be habitable and they said if you added more mass it could be. I was wondering if that could effect its radius, thats all.

First, there is not enough mass in the inner solar system other than what's in planets to make Mars habitable, but if somehow you could do it, once it cooled off enough to visit again after the bombardment, its radius would be bigger.

Planetary compression due to gravity and inner pressure generally increases slower than planetary size up to planet sizes more massive than Jupiter. There are formulas for this.
Of course you can arbitrarily increase a hypothetical planet density up to a point by increasing metal content (theoretically up to around 100% iron content) which would reduce radius for the same mass.
