Tool Introduction
The "B Paper Standard Size Inquiry" tool is a professional and practical online service designed to provide users with detailed standard size information for B series paper (from B0 to B10). The tool displays the dimensions of each paper type in a clear table format, including precise values in millimeters (width × height) and inches (width × height), greatly facilitating designers, printing industry professionals, and any users who require accurate paper dimensions. In addition, the tool is equipped with an intuitive B series paper size comparison chart to help users more visually understand the relative sizes and proportions of different paper types.
How to Use
- Access the Tool Page: Directly open this tool page, and you will immediately see the complete B series paper standard size comparison chart and comparison diagram.
- Consult the Size Comparison Chart: The comparison chart clearly lists the size data for B0, B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, and other paper types. You can find the specific paper size you need, including both millimeters (width × height) and inches (width × height) units.
- View the Size Comparison Chart: Below the table, a B series paper size comparison illustration is provided to help you quickly understand the relative size relationships between different paper sizes visually.
- Mobile Operation Tip: On mobile devices such as phones or tablets, if the table content is wide, you may need to swipe left and right to view all columns of complete data.
Usage Example
This tool is very intuitive and convenient to use, requiring no complex operations. Here is a simple usage example:
- Operation Demonstration: A user visits the "B Paper Standard Size Inquiry" page.
- Example Search: Suppose you need to query the specific dimensions of B4 paper.
- Expected Result: You will directly find the "B4" row in the comparison table and be able to see its millimeter dimensions as "250×353" and inch dimensions as "9.8×13.9". At the same time, through the comparison chart below, you can also visually understand the relative size and position of B4 paper within the entire B series.
For example, a table excerpt for querying B4 paper size:
| Size |
Millimeters (W×H) |
Inches (W×H) |
| B4 |
250×353 |
9.8×13.9 |
Frequently Asked Questions
- Q: What input formats are supported? A: This tool is an information query tool and does not accept any user input parameters or formats. You only need to visit the page to directly view the standard size data of B series paper.
- Q: What is the output format? A: The output results are presented in an intuitive HTML table format showing the size data of B series paper, supplemented by a B series paper size comparison chart. The table content includes size model, millimeters (width × height), and inches (width × height) information.
- Q: How are B series paper sizes defined? A: B series paper sizes are standards stipulated by the International Organization for Standardization (ISO 216). Their design is based on the A series, but the area of B0 is √2 times (approximately 1.414 square meters) that of 1 square meter, not A0's 1 square meter. The aspect ratio of B series paper also remains 1:√2 (approximately 1:1.414), and the area of each B(n) size is half the area of the B(n-1) size.
- Q: What scenarios are B series paper mainly used for? A: B series paper is typically used in printing, such as posters, bookbinding, envelopes, postcards, advertising flyers, and various special printed materials that require sizes between those of the A series.
Notes
- The B series paper size data provided by this tool strictly adheres to the international ISO 216 standard, ensuring its accuracy and authority.
- The millimeter and inch dimensions in the comparison table are precise standard data; please use them as the primary reference.
- The "B Series Paper Size Comparison Chart" below is only a visual tool to aid in understanding the relative sizes of different paper sizes and should not be used as the final basis for precise measurement or printing.
- When browsing this page on a mobile device, if the table content exceeds the screen range, you can swipe left and right to view the complete size data.
- All dimensions are expressed in "width × height" format, where "width" refers to the shorter side of the paper and "height" refers to the longer side.
Introduction to B Series Paper Standard
B series paper sizes are a set of paper standards defined by the International Organization for Standardization (ISO 216), which, along with the more commonly encountered A series and C series, form the international paper size standard system. The B series is designed to fill the gaps between A series sizes, offering more size options to meet the needs of different printing and application scenarios.
Similar to the A series, the B series also follows the 1:√2 aspect ratio principle, meaning the longer side of the paper is √2 times (approximately 1.414) the shorter side. The advantage of this ratio is that when a sheet of paper is cut in half, the two smaller sheets still maintain the same aspect ratio, which greatly simplifies scaling operations in design, copying, and printing. B0 paper is the base size of the B series, and its area is defined as √2 square meters (approximately 1.414 square meters), not A0's 1 square meter. This means B0 paper is larger than A0 paper, so B series sizes are generally slightly larger than the corresponding A series sizes (e.g., B4 is larger than A4).
B series paper is widely used in various printed materials and stationery products, such as books, manuals, posters, envelopes, postcards, and various documents requiring larger or intermediate sizes between A series dimensions. Understanding the B series paper standard is crucial for graphic designers, publishers, printers, and anyone who needs to handle paper sizes.
