Can you explain a bit more what the challenge you're having with it is? Is it the size of the area, drawing the terrain, etc.?
Basically, I've got this map. https://i.imgur.com/74hkJEl.jpeg I just need to know what size to ask for when I take it up to Staples to get printed out; because it's too difficult for me to redraw on my grid-mat.
Nice to see my stuff getting Used :D
That map have 40x40 Grid, I Recomend 1x1 Inch Squares so I would Print it 40x40 Inch (Or 100x100 cm) Most of my Maps are 40x40 or 20x20 (its an early map on my new Stuff the Grid size is noted)
