In our previous work and life, we encountered a lot of questions about paper size and paper weight, and we were inspired to think that there are many other people in the world who may have the same problems or confusion as us, so we created this website. On this website, you can find a comprehensive and detailed list of current international standard paper sizes, including ISO standard paper sizes, US standard paper sizes, and some other special paper standard sizes.

All articles were well researched to ensure the accuracy of the information, but we are afraid that there will still be omissions. In addition, since the people who created the website are non-native English speakers, there should be mistakes in grammar, spelling or expression in English. We sincerely hope that you can contact us and help us correct them.
