This is a nicely sized 8.5" x 11" book, which allows the images to be a little larger, giving you more room to color. Margins are well-spaced, so you can more easily cut out pages from the book. Thank you for considering a "Roko Puzzles" coloring book. This book was lovingly crafted by an independent book maker who enjoys all kinds of activity books. The goal was to make this one of the best coloring books available, with a truly broad assortment of quality images.
