The dimensions are wrong. The description reads 20.5’ x 16.5” (length x width) when it’s actually 20.5” x 16.5’ (width x length). The problem is I have 9 ft walls so one roll only gives me 1 panel not 2 and I had to buy twice the number of rolls. However it was worth it because the wallpaper is stunning!! Just be careful when ordering if you have 9’ walls.
