How does the size of the combustion chamber affect the compression of the engine?

How does the size of the combustion chamber affect the compression of the engine?The smaller the chamber the higher the comp. ratio.Also keep in mind the a small chamber "shrouds" the valves some.

Are there any advantages of having a larger combustion chamber?

It's a long thread but you might read it to try to figure this out.
