The rolls are only 8 feet long by 3.5 feet wide. It's rather pricey and the calculator online didn't calculate the correct amount of Wallpaper I would need. The roll isn't long enough for my 9 foot ceiling height and I would need 3 rolls just to cover a 9 x 4 wall. The product itself looks good, but again not really for using on walls. It would be fine for a very small area or project.
