Reddit reviews Ampad 24-032R Evidence Flip Chart Pads Ruled with 1-Inch Squares, 27x34, 50 Sheets Per Pad, 2 Pads Per Pack

Thats nice, but a chessex battlemap is durable and amazing. Not even that expensive. They last years and are well worth the investment. Mine is 10 years old and I'm pretty sure I'll get another decade out of it at least.

If you want to premap out rooms ahead of time instead of drawing on the spot? Get something like this. It's 50 sheets of 24x37, that's a lot of rooms/hallways/buildings to map out. If you do a lot of DMing then they even come in a 4 pack.

Think that is overpriced? Get a roll. The grid isn't exactly an inch, but it's close enough. We're gaming, not trying to land on the moon. It's 34" by 200 feet. That's enough for entire campaigns.

Is 200 feet too much investment for you? 8 bucks gets you 12 feet, that's twice the length of typical wrapping paper (I seem to find 6 feet the norm). Hell, they threw the word "gaming" into the name and seem to have forgotten the 200% price mark up that normally accompanies the term.

Wrapping paper has to be the single most ridiculous way to do D&D. They don't all have grids, and the price is not great. Maybe if it goes on some sort of supersale and you can ensure that it has grids on the other side, go for it, but there's just better sources of grids available out there.

You can buy a roll of gridded graph paper for cheap, and it's washable (just use as little water as possible since it's paper). Or buy a pad like this: http://www.amazon.com/24-032R-Evidence-1-Inch-Squares-Sheets/dp/B00006I9X8/ref=sr_1_3?ie=UTF8&qid=1420658092&sr=8-3&keywords=grid+chart+paper

and predraw all your maps in advance.
