It's wide enough that an Orc could comfortably swing a greatsword in any direction from the center of the tunnel. Since the average height of an Orc is 8'0", and a standard greatsword is just under 5 feet long (which you'd then have to double, to make sure it works from either side), that gives us a minimum requirement of 18 feet for the ability to swing the sword in any direction. Since the minimum isn't exactly "comfortable", though, they added another foot of room on both sides, making the tunnel 20 feet wide. For height, they had to add the approximate length of one arm (they rounded up to four feet) to the height, then added in the approximate length of the sword, then gave another three feet of height for comfort, giving a height of 20 feet. So, it's 20' wide, 20' tall, and an unknown length. And before anyone gets on me about the logistical difficulties inherent in digging a structurally sound tunnel with those dimensions in six months, keep in mind magic is a thing. I know it would be 8000 cubic feet of earth for a 20x20x20 room, and I realize that would probably be a few hundred tons of earth. They just threw a bunch of Terramancers at the problem.
