At some point in the near future I'd like to create a replica of the Marauder's Map, but I need a bit of help. First of all, how tall and wide is the map when completely opened and then again when folded? I'd like to draw this completely by hand (except the front cover), without any printing, and I've started a mission to collect as much reference material as possible. I'm also going to search for clips online to get an idea on how the map opens and folds, and I'll also be using the Noble Collection map as a reference point.
The replicas are 15.5 inches by 8.25 inches closed, and 15.5 inches by 72 inches opened. It seems like this is consistent with the one in the movies. you can compare the height next to Harry's wand prop (which is 11 in.), seen here displayed. Hope that helps.
