Grid: 1 inch HEX & 1 inch Square
"This mat is massive! If you want to be able to draw an entire dungeon complex this is the mat that will probably let you do that. I've been using the one I purchased since 2005 and it's been great. The grid hasn't faded and it works great with the wet erase markers. Only thing you need is to make sure you have space to use it. You can keep it folded in half as well."
