B纸张尺寸转PX

Tool Introduction

"B Paper Size to PX" is a practical online tool designed to help users accurately convert the physical dimensions of international standard B-series paper (from B0 to B10) into digital image pixel (PX) width and height, based on specified DPI (dots per inch) or PPI (pixels per inch) values. Whether for digital image design, web image size planning, or preparing high-resolution files for print output, this tool provides convenient and efficient size conversion services, ensuring your digital content perfectly matches paper dimensions.

How to Use

1. In the "Paper Size" dropdown menu, select the B-series paper size you need to convert, for example, "B5".
2. In the "DPI/PPI" input box, enter the resolution value you wish to use. The default value is 96, which you can modify according to actual needs (e.g., screen display is typically 72 or 96, print products may be 300 or higher). This field is required and only accepts numbers.
3. The tool will automatically calculate the corresponding "Width" and "Height" pixel values in real-time based on your selected paper size and entered DPI/PPI value. The calculated results will be displayed in "PX" units in the corresponding read-only input boxes, allowing you to view and copy them directly.

Usage Example

Suppose you need to convert B5 paper size to pixel values at a resolution of 300 DPI to create a corresponding canvas size in design software.

• Example Input Data:
  • Paper Size: B5
  • DPI/PPI: 300
• Expected Output Results:
  • Width: 2079 PX
  • Height: 2953 PX
• Specific Operation Demonstration:
  First, select "B5" from the "Paper Size" dropdown list. Then, enter the number "300" in the "DPI/PPI" input box. The tool will immediately display the calculation results, where "Width" is "2079 PX" and "Height" is "2953 PX".

Frequently Asked Questions

• Q: Which B-series paper sizes does this tool support?
• A: This tool supports the conversion of 11 standard B-series paper sizes, from B0 to B10, which you can freely select from the dropdown menu.
• Q: What is the difference between DPI and PPI? How do I choose an appropriate DPI/PPI value?
• A: DPI (Dots Per Inch) usually refers to the output resolution of a printer, while PPI (Pixels Per Inch) refers to the pixel density of a screen display or image file. When calculating paper pixel dimensions, these two concepts are equivalent in this tool, both representing the number of pixels per inch. Choosing an appropriate DPI/PPI value depends on your final use: for example, 72 or 96 is often chosen for web display, while 300 or higher is common for high-quality printing.
• Q: Are the calculated pixel values exact integers?
• A: Yes, since pixels cannot have decimals, this tool will round the floating-point calculation results to the nearest integer pixel value.
• Q: Which B-series standard does this tool use for calculations?
• A: This tool defaults to using the international ISO B-series paper size standard (e.g., B0 is 1000mm x 1414mm) for calculations.

Notes

• Please ensure that a valid positive integer value is entered in the "DPI/PPI" field to guarantee the accuracy of the calculation results. Entering non-numeric or negative values may lead to errors or meaningless results.
• The pixel dimensions of paper have a linear relationship with the DPI/PPI value. The higher the DPI/PPI value, the larger the generated pixel width and height, the richer the image details, and the larger the file size.
• This tool's calculations are based on the international ISO B-series paper size standard. If you are using paper sizes from other regions (e.g., JIS B-series), please note that there may be slight differences.
• Before proceeding with professional design or printing, it is recommended to double-check whether the calculated pixel dimensions meet your specific project requirements.
