We put our own grid on a chalkboard using indelible-ink felt pens*. Half an afternoon's work that you only have to do once, 'cause it lasts for a lifetime. 2-inch grid, 10' squares, works like a hot damn.Interesting - I don't think I've seen a 2" grid!
Back in the Day here in UK Games Workshop put 28mm metal minis on 2 cm square bases, so you could almost have got 3 across a 2"/5cm corridor. But GW's own dungeon floorplans used a 2 cm = 5' scale so too narrow.
Then during play, when it's needed either I draw the map on the board (using chalk, of course) or the players do from my description.
* - a simple ballpoint pen works too, but it doesn't have the same staying power and eventually needs to be re-done.
Never minding that there are no clarifications for 4 large targets attacking a medium. If I'm half in something's front and half in it's flank, does the target retain it's shield bonus? If I'm half in the rear and half on the flank, does it get it's Dex bonus?
