When I first started playing D&D, there seemed to be an unspoken rule that published dungeon maps had to fit on one or possibly two 8.5" x 11" pages. I have a hard time remembering any modules that included maps larger than that, though there undoubtedly were some that escape me right now. With the dawn of the Electrum Age and then the Silver Age, dungeon maps became much more complicated. Not only were they frequently isometric, but they were just as frequently printed as posters. This made them unwieldy to use at the table, at least me, which is why, for all that I drooled over them in the abstract, I found that, in practice, they were less than ideal.
Which brings me to today's question. I've been giving some thought to the best presentation of Dwimmermount's maps for use by outsiders. Being a megadungeon, some of its levels are large and sprawling, while others are smaller and more compact. How to present these maps? Poster-sized pages sprang immediately to mind, but I remember only too well how hard such things were to use in actual play. On the other hand, printing a 100-room level on a single page would necessitate shrinking it down to a fairly small size, which might prove equally difficult to use.
So, assuming that money were no object, what would you recommend as the best way to present Dwimmermount's maps -- or indeed any megadungeon's -- in printed form? What would you find best facilitated speedy and enjoyable play at the table?
