I'm checking out the Dallas sectional in digital form for my own amusement. The image, in TIFF format, is massive. I wonder, if you buy one of these in printed form from the FAA (or your local GA office), what would be the sheet size of the map?
The New York Sectional (the only paper one I have on hand right now) is 20 3/4 X 59 1/4 inches. You are correct, they are large and printed on nice thick paper.
