Designers, printers, and procurement professionals often need to quickly verify the exact dimensions of German paper sizes under the ISO 216 standard to avoid design misalignments or purchasing errors. This tool is a static German standard paper size reference chart based on the ISO 216 (derived from the German DIN 476 standard) international paper size system. It directly outputs the exact width and height values for A-series (e.g., A4, A3) and B-series paper. The ISO 216 standard paper definition is based on an aspect ratio of √2 (approximately 1.414), ensuring the proportions remain the same when folded in half, with dimensions based in millimeters (mm). You don't need to input any data; simply browse the reference chart to get the millimeter and inch conversions for standard sizes ranging from 4A0 to C10.
Q: What is the standard size of A4 paper in millimeters and inches?
A: The standard size of A4 paper is 210 mm × 297 mm (width × height), or 8.27 inches × 11.69 inches. This is the most commonly used office paper size in the ISO 216 system.
Q: Do the results in this chart include bleed or actual finished sizes?
A: No. This tool provides the theoretical uncut sizes defined by the ISO 216 standard. The finished size of actual printed materials usually includes a "bleed" area (typically extending 3mm on all sides), and the trimmed size of book or manual inner pages may vary slightly depending on the binding method. Please be mindful of this distinction when using the chart.
The data in this tool represents static standard values, suitable for design reference and preliminary planning. Please note: Actual printing or cutting may result in a tolerance of ±1-2mm due to equipment and processes. The "width × height" displayed in the table defaults to portrait (vertical) orientation; you need to swap the values for landscape orientation. This tool does not provide custom size calculations or non-standard size queries.
For printing and graphic design professionals, understanding the √2 ratio logic of ISO 216 is crucial. It not only ensures proportional consistency when scaling but also means that adjacent sizes in the A-series (e.g., folding A3 in half gives you A4) have exactly half the area, greatly simplifying imposition and material estimation. A typical application example: When you need to design an A4 flyer and account for a 3mm bleed on all sides, your design canvas size should be set to 216 mm × 303 mm (i.e., 210+6 × 297+6). Furthermore, if you receive a printing request in inches (such as 8.5" x 11"), which is close to but not standard A4, you should use this tool to verify and inform the client of the difference between standard A4 and US Letter sizes to avoid production errors.
