The book sleeve fits most hardback books (even BOTM) or multiple paperback books. Book sleeves come out to about 8.5"x11". These are handmade and each sleeve is unique with the placement of pattern and sizes may not be exactly 8.5"x11".
*Please note that each item is handmade, so dimensions and patterns may not be exact. Handmade means they are uniquely made with love and may have discrepancies.
