Standard paper sizes provide a convenient and efficient means for designers and printers to communicate product specifications and control costs.
ISO, (The International Standards Organisation), The ISO standard provides for a range of complementary paper sizes, as shown in the tables. Generally speaking, A sizes are used for printing everything from posters and technical drawings to magazines. B sizes are used for printing books; while C sizes are used for envelopes that will hold the A sizes.
There are also two series of paper sizes that are also based on the ISO standard and are sizes used by printers! These are the RA and SRA series. They're slightly larger than the A series to provide grip, trim and bleed. E.g. A1 format = 594 x 841...The SRA1 equivalent would be 640 x 900 mm, this is bigger to allow for trimming to the final size.
Each size in the series is double the size of the previous one. So A3 paper is double the size of A4. But the cunning bit is this: the ratio of width to height remains the same throughout the range. So you can enlarge or shrink the image to your heart’s content and it will fit the next page size (in fact ANY page size) perfectly. The proportion of width to height remains constant.
After researching formats I had the idea to use the formats to my advantage and possibly produce 4 booklets, all differing in A sizes. This means that when they're placed together in my container, you'll be able to visualise the paper formats, the bright coloured stocks should also light up the box.
