This website was initiated by a team of enthusiastic Asian netizens.

In our previous work and life, we encountered a lot of questions on 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 confusions 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, US standard, and some other special standard for paper 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 we are non-native English speakers, there should be errors in grammar, spelling or expression. For those we apologize, meanwhile we sincerely hope that you can contact us and help us correct them.

Thanks to our sponsor inXpection Co, a very nice and responsible China 3rd party inspection company. You are the best.
