The sizes of the rugs are right there on the side... where it says size... They are big - the smallest one is 3 feet by 2 feet, the largest is 12 feet by 9 feet. It takes a large image if you want to offer up to the largest size. I've used only vector images to this point to avoid any problems with resolution, but I'd expect with pixel based images, if you will get the resolution warning if your image is any smaller than 150-200 dpi at the size of the rug you are attempting to make.
