If you live in the United States or Canada, the usual printer paper measurements for most documents are 8.5 inches by 11 inches for letter paper. Much of the remainder of the world uses A4, which is 297 millimeters by 210 millimeters. One arty scale model is exactly 1 square meter. The area is often quoted as 86.4 square inches (2070 square mm), but this includes margins. Without margins, the area is 731.6 square inches (17750 square mm). This means that one square meter of art can be printed with seven sheets of paper, if all other conditions remain the same. Paper dimensions and density are two important factors that affect how much can be printed per sheet. The more ink there is on one piece of paper to print an image, the better. That's why it's important to choose the right paper for the job. In general, printing processes use either wood pulp or cotton fibers as a base, both of which can be recycled. Recycled paper has been used before its quality began to suffer from multiple reuses. Printers usually offer different sizes and qualities of paper. It is best to select a paper size that is close to the shape and size of the artwork to be printed. This will avoid having to crop your image later on. The quality of paper affects how well it prints.
