In Harry Potter and the Prisoner of Azkaban, whilst Professor Snape is covering for Professor Lupin, Snape sets an assignment to write two rolls of parchment on the werewolf and emphasises recognising it.
The students, including Mr. Potter, react as if he has set an essay of 7000 words. Something that would take a considerable amount of time. Two rolls of parchment suggests two sides of A4/letter size. Like the standard paper you find in a household printer. This would take, I guess, on average what...an hour..two, maximum?
Do we know of a more accurate dimension/size for ‘two rolls of parchment, considering the students reaction to the assignment?
