IT would be nice to know how big the map is (in inches when printed out at 100%) and in hexes Length x Width,

FYI, after downloading it's an odd scale of 24.433" x 23.487" (measured in GIMP). Rescaling it to 24"x24" didn't result in any odd stretching or anything for me. Still it's strange that the artist would choose those dimensions. I guess trimming the outer edges manually could square it up at under 24x24.
I think I can solve the "odd" scale of the map for you. Since this is an "Outdoor Survival Hexmap", it is based on the Avalon Hill board game Outdoor Survival (which was a piece of equipment needed/strongly recommended) when playing the Original edition of D & D. The map in that board game is 22" x 24". I don't think this is an exact reproduction (in terms of what is in the hexes, it is hard to tell from the samples provided), but rather a map in that style and for the same purpose.
