It depends on the story and the author.
In the early days of Marvel Odin's battles shook the entire multiverse to some degree and he fought enemies one of which whom forged his sword in the flames of an exploding galaxy. But he's really fallen since then, and currently I'd put the power of his magic at a planetary scale.
Galactus is even more difficult to gauge, but at the height of his power he was able to wipe out multiple galaxies as a side-effect of his battle against Tyrant, and in Annihilation he destroyed three star systems.
If you want a more detailed and reliable answer ask Mr Master. Marvel cosmology is kind of his forte.
