Gravity becomes lower at higher altitudes, or what do you mean?
The bigger aplanet, the further away its surface from its center of mass, which decreases gravity. A planet's surface gravity is mostly affected by its mass and density. This is why Saturn, despite being much bigger than Earth, still have roughly the same surface garvity.
