What is the A4 size?


What size is A4 paper?  The most common paper sizes used in the UK for printing and stationery are named using the letter A, also known as International Paper Sizes. The range begins with tiny A10 (37mm x 26mm) and goes all the way through to the mighty A0 (1189mm x 841mm).

To many people wordwide, excluding North America and Canada, the most familiar paper size size is A4 (a familiar 210mm x 297mm). It is commonly used for letters and correspondence in the UK and it is the standard paper size for most home printers. I bet you’ve seen, used and/or scribbled on at least one piece of this today.

With A sized paper, however many times you double the short edge or half the long edge, it will always have the same width to height ratio. For example, the dimensions of A4 paper are 210x297mm, and half of A4 equals A5, and double A4 equals A3.


At present, the weight of A4 paper in the market is almost 80g, except that a few manufacturers will provide 70-75g in order to save costs, because the price of paper roll raw materials is increasing much.For A4 copy paper roll, current price is USD 1,000/ton ( base on 17th,March,2022)
