Tool Introduction

The "German Standard Paper Size Lookup" tool is a convenient online resource designed to help users quickly and accurately find standard paper sizes widely used in Germany and internationally, based on the ISO 216 standard. It provides a clear comparison table, detailing various standard paper models and displaying their precise dimensions in both millimeters (width × height) and inches (width × height), two commonly used units. Whether you are a designer, printer, or general user, this tool allows you to easily obtain the required paper specification information, greatly facilitating design, layout, and printing work.

How to Use

Access the Tool Page: Open the "German Standard Paper Size Lookup" tool page.
Browse the Comparison Table: In the center of the page, you will see a table titled "Standard Size Comparison Chart (German Paper Sizes)".
Find the Desired Size: Directly locate the paper model you wish to query (e.g., 4A0, 2A0, etc.) in the table. The second column of the table will display its dimensions in millimeters (width × height), and the third column will show the corresponding dimensions in inches (width × height). This tool requires no input; users only need to consult the table to obtain the necessary information.

Usage Example

Suppose you are designing a large print and need to know the exact dimensions of a standard 4A0 paper.

Example Operation: You just need to open this tool page and find the row with "4A0" in the "German Paper Size" column of the displayed comparison table.
Expected Output:

German Paper Size Millimeters (Width × Height) Inches (Width × Height)

4A0 1682×2378 66.22×93.62

By consulting the table, you will clearly obtain the dimensions of 4A0 paper as 1682 mm wide by 2378 mm high, or 66.22 inches wide by 93.62 inches high.
Specific Operation Demo: Users do not need to input any data; they just need to scroll the page and find the corresponding paper model row in the table to view the precise dimension data.

Frequently Asked Questions

Q: Which paper size standards does this tool support? A: This tool primarily queries German paper sizes (following the international ISO 216 standard), including common specifications such as A series and B series. ISO 216 is a globally recognized paper standard, widely used in Germany and other countries.
Q: What are the dimension units? A: The tool provides two common units: millimeters (mm) and inches (in). All dimensions are clearly listed in a "width × height" format.
Q: How do I find a specific paper size? A: You don't need to enter any information; just locate the corresponding row in the comparison table displayed on the tool page based on the paper model (e.g., 4A0, 2A0, etc.) to view the millimeter and inch dimensions of that paper.
Q: Why are common sizes like A4, A3 not shown in the table? A: This configuration example only shows some extra-large sizes. The actual "German Standard Paper Size Lookup" tool would typically include all common paper sizes under the ISO 216 standard, such as A0, A1, A2, A3, A4, A5, etc., as well as B series sizes.

Notes

Data Accuracy: The data provided by this tool are theoretical precise dimensions under the international ISO 216 standard, suitable for most design and printing scenarios.
Actual Usage Differences: Actual printed or cut paper sizes may have extremely minor deviations due to equipment precision, cutting tolerances, and other factors, but are usually within an acceptable range.
Lookup Method: Users obtain information by browsing and consulting the table, without any input operations, ensuring ease of use.

Introduction to ISO 216 Paper Standard

ISO 216 is a series of paper size standards established by the International Organization for Standardization (ISO), which defines the dimensions of A series and B series papers, based on the German standard DIN 476. The core of this standard is based on a length-to-width ratio of 1:√2 (approximately 1:1.414). This means that if a sheet of paper is folded in half along its longer side, the new paper will still maintain a 1:√2 aspect ratio, and its area will be exactly half of the original. For example, an A0 paper has an area of 1 square meter, A1 is half of A0, A2 is half of A1, and so on. This design allows paper to maintain perfect proportions when scaling and copying, greatly improving the efficiency of printing and design, and is a widely adopted standard in the printing and office sectors globally.

Paper Size Width and Height

In the representation of paper sizes, we typically see the format "width × height". In the ISO 216 standard, it is usually agreed that the shorter side is the width and the longer side is the height. For example, the standard size of A4 paper is 210mm × 297mm, meaning its width is 210 millimeters and its height is 297 millimeters. When the paper is used horizontally, for example, when printing a document in landscape orientation, the paper's "visual width" will become 297mm and its "visual height" will become 210mm, but its physical dimensions of width and height remain unchanged. This unified representation helps avoid confusion and ensures accurate communication and use worldwide, especially in design or printing projects involving international collaboration.
