There are reasons to make larger objects less dense, especially if they need to traverse the ground. Pressure = Force / Area. You will have a given amount of force based on mass and gravity, that is applied across the entire footprint of the mech. In order for it not to sink into the ground, especially in muck, you will want a large surface area for its feet, because you need to reduce pressure on the ground to prevent sinking down into it.
Now consider this issue of pressure on joints, actuators, and the like. You most definitely will want to make the more massive objects less dense, given a fixed material tensile strength.
But ya know...engineering is not realistic...amiright?
You would be correct, except for few things;
1) That mainly applies to ground preassure, IE the size of the feet.
1.5) Making the feet larger doesn't make the mech less dense. It just gives it bigger feet.
2) While "as dence" as a smaller object, the larger object already has an increase in size for those joints/actuators/etc.
3) It doesn't take into account support given by mynomer musculature.
4) We don't know the actual "tensile strength" of the various Armors and Materials that compose the structure (Endo-steel, XT, FT 10X, etc).
4.5) Tensile strengths between mechs are somewhat different as they use different materials for structure and armor from mech to mech (except for "endo-steel").
