as ithica said but i use 110lb cardstock from walmart or office supply most things on here are in letter format but u can get A4 also as far as how much each piece varies due to low def or high def once u get all the pieces scaled to size you can count how many sheets it will take for each piece and that will give you a real close estimate for example it took 33 pages for my high def chest piece but again depends on how much detail you want
