I found this article on Guitar Scale Length, which explains the concept of scale length on guitar and how your choice of instrument determines much more than how it feels in your hands.
In addition to this article, there are many other resources available to understand the nuances to scale length decisions, such as D'Addario's information on string tension for all of the guitar sets (see their strings web-site and use the search bar for details on any D'Addario set for details).
