There are two standard paper sizes, Letter (popular in the US) and A4 (popular elsewhere). Your printer should be automatically setup to your local standard size.They are very similar in size, the difference being just a few cm/inches. Our artwork can fit either but you might want to trim any excess space that shows up due to ratio difference between our artwork and your paper dimensions. In regards to paper quality, the printing should look fine on normal paper as long as you set your printer’s print setting to maximum quality. However, if you want maximum quality you can buy photo-quality paper at your local stationary shop.
