Well, according to Newton's formulas, the farther away we get from the centre of mass of an object the lower the gravity becomes, so while the volume
and mass increase that doesn't mean that the gravity does.
I will try some calculations.
Edit: after some calculations it looks like a change in the Earth's (or any other body) radius would create a proportional change in the gravity. If
the Earth had half it's radius but the same density the gravity would be half of what is now; if the Earth's radius would grow 10% then the gravity
would be 10% stronger.
I think that the most sensitive weighing scales would be enough to detect a change in the Earth's size.
