So upon attempting to quantify some shit in SS, Chaos suggested I use Lanayru Desert as a way of garnering the continent of Hyrule's size, and thus a scale to use.
Thousands of years before the events of Skyward Sword, before the severe climate change resultant of the war between Hylia and Demise, the Sand Sea of Lanayru Desert was once known as "the Great Sea" (separate from Wind Waker's Great Sea, quite obviously). We get to sail this sea while aboard Skipper's Sandship due to the power of the Timeshift Stones. Chaos explained that vessels as large as Skipper's ship would not have been made were it not for the necessity of traversing enormous bodies of water. Therefore, given Zeldaverse's Earth-like nature, it seems reasonable enough to take the area of our smallest sea, the Gulf of California, and apply it to the surface area of the Sand Sea, which was formerly the Great Sea.
Well, on to the scaling, I suppose.
(168*86)/2=7224 px^2
The area of the Sand Sea on this map is then 7224 px^2.
According to Wikipedia, the surface area of the Gulf of California is roughly 160,000 km^2.
Working backwards from the square law...
sqrt(160000/7224)*86=404.734km
The entire map is about 793px across.
(404.734/86)793=3732km
Makes sense, given what we know about our continents, namely Australia. Granted, this isn't the entire continent of Hyrule, but it's a sizable chunk.
