The ring has to fit both the piston and bore- correctly. There's no "oversize" ring for a standard piston or bore. There are 'file to fit' rings, these are made to have the end gaps hand finished for a more precise control over the end gaps. But the ring diameter would still be standard, or whatever oversize the bore is.
