The dimensions of the A series paper sizes, as defined by ISO 216, are given in the table below in both millimetres and inches (cm measurements can be obtained by dividing mm value by 10). The A Series paper size chart to the right gives a visual explanation of how the sizes relate to each other - for example A5 is half of A4 size paper and A2 is half of A1 size paper. www.papersizes.org

If you make A2 sized cards and need a smaller mat for your card...cut the sheet into quarters and store the extra mats in a box indexed by color...especially nice if you use a specific brand of cardstock.
