Map Dimensions?

[Jamie the Jasper]

Bear in mind that if you're working with a fantasy world that's vaguely equivalent to medieval Earth, map makers might not necessarily even be aware that they live on a globe, so the issue of projection becomes moot. The entirety of the world may not even have been mapped. The map could even be designed to reflect things other than perfect geographical accuracy, such as the centralised strength of an empire - as was the case for many real maps in our history. Many of these maps were all kinds of different shapes and sizes, depending on what the map was designed for and what kind of materials were available. Something like that might be a more characterful and immersive role playing prop than a geographically and scientifically accurate map of the entire world. Maybe something to bear in mind.

For starters, I think that the purpose of Squessibionaro's request is how to go about crafting a map of the world so that he, as the GM, can use it as a tool, not simply provide a prop for his players.

Furthermore, I would challenge the notion that map makers of medieval Earth were not aware that they live on a globe. The fact is that most cartographers (then known as chart makers), from the time of Idrisi on, knew the Earth was a globe. However, such knowledge was inconsistent with the teachings of the Catholic church whose doctrine advocated otherwise.

Having said all of that, it would be pretty cool to have a scientifically accurate map of the world (for the GM) and a set of cartograms as props for the players.
