My 19th level Shaman's character sheet, without counting rituals or item cards, is 6 pages long - 3 pages of basic character sheet (front, items, and features/feats) and 3 pages of power cards. In addition, she also has 3 pages of item cards, a moderately generous amount, if you ask me, and 4 pages of rituals.
I'm posting about my 18th level gnome mage only to illustrate how far this can range. I don't think these numbers are normal and it would be a mistake to take them as such: 3 pages of traditional character sheet (front, items and features/feats), plus 5 pages of powers (due to the expanded spellbook), plus 5 pages of item cards (he has a lot of low level items that he swaps out with the rakshasha claw familiar).
