In the end, a rough estimate is that the map goes from 85°N to 0° from north to south, and spans about 210° from west to east. This makes the distance from Old Sharlayan to Limsa Lominsa by boat at about 4200 km. From the lore description (a fortnight for a fast trader) I originally estimated 5000 km, so that tracks; maybe Hydaelyn is simply 20% larger than Earth.
Nothing much to do with Project Ironheart, really, I just though someone might find it interesting. For all we know, Hydaelyn might not even be a spheroid.
