If you are planning to use a printing or book binding company outside North America, it is useful to know how your book will translate to European paper formats. There is a lot of information available online to allow you to compare North American and European paper sizes. This information might be useful if you are planning to publish a book for distribution in the European market. North American sizes (used in the US, Canada and Mexico) are non-metric, while Europe, Japan and much of the rest of the world use metricated paper sizes based on the ISO standard.
