Something that may be of marginal interest. A size comparison of various fantasy worlds that I created:
At top-left is Westeros/Essos (the HBO version of the latter) from George R.R. Martin's A Song of Ice and Fire. Next to it on the top line is J.R.R. Tolkien's Middle-earth, with Ansalon from the Dragonlance world next to that. Below them is Robert Jordan's Wheel of Time map (which was tricky to get right, as the distances given in the books are sometimes contradictary). At bottom-right is Raymond E. Feist's Triagia (on the world of Midkemia), the setting for most of his Riftwar fiction. At bottom-left is Faerun, the principal continent of the Forgotten Realms world.
Something that is surprising here is how small Middle-earth is compared to these other, later-created fantasy worlds.
