What are paper sizes?<\/strong><\/h2>\nPaper sizes are standard sizes used worldwide for documents, flyers, cards, posters and printed matter. The best-known series is the A-series. Here, each size always has the same ratio. An A4, for example, is exactly half the size of an A3. This makes the formats practical for printing, scaling and folding.<\/p>\n
