The Earth shows no measurable change in size on a yearly basis, though we know from observing other planets that as the core cools, they shrink because we can observe ridges formed in the crust.
The size of Earth is amazingly stable, so much so that it was something that attracted the attention of Earth scientists. The Earth's core cools a little each year, so it should shrink a little. The core is about 5,000 degrees C and has cooled only a very small amount, less than 100 degrees in a billion years. The slow cooling is partially attributed to the generation of new heat from radioactive decay of heavy elements like Uranium. It is not completely clear however and a matter of continuing research.
