Business Card Size to PX Converter

Tool Introduction

Business Card Size to PX Converter is a professional online tool designed to help designers, print professionals, self-media creators, or anyone who needs to convert physical business card dimensions (millimeters) into digital pixel (PX) dimensions. This tool can quickly and accurately calculate the corresponding pixel (PX) width and height based on your input of standard business card sizes (such as common specifications like 90x54mm, 85x54mm) and the desired DPI (dots per inch) value, greatly improving design and production efficiency and ensuring that design drafts meet printing or digital display requirements.

How to Use

1. In the "Business Card Size" input fields, enter the length and width of the business card you need to convert (unit: millimeters mm), or select a common business card size from the preset options.
2. In the "DPI" input field, enter the DPI value you wish to convert to (e.g., 300 DPI, 350 DPI commonly used for print, 72 DPI, 96 DPI commonly used for screens).
3. Click the "Convert" button.
4. The tool will immediately display the corresponding pixel (PX) width and height of the business card at the selected DPI.

Usage Example

Suppose you need to create a high-resolution print design for a standard 90x54mm business card, planning to output it at 300 DPI accuracy. Here are the specific steps and expected results:

• Example Input Data:
  • Business Card Width: 90mm
  • Business Card Height: 54mm
  • DPI: 300
• Expected Output Results:
  • Width (PX): 1063 PX
  • Height (PX): 638 PX
• Specific Operation Demonstration:
  1. Enter "90" and "54" respectively in the "Business Card Width" and "Business Card Height" input fields.
  2. Enter "300" in the "DPI" input field.
  3. Click the "Convert" button.
  4. The result area will display "Width: 1063 PX", "Height: 638 PX".

Frequently Asked Questions

• Q: What is DPI? How much DPI should I choose? A: DPI (Dots Per Inch) is a unit for measuring image resolution. For print products, it is generally recommended to use high DPI, such as 300 DPI or 350 DPI, to ensure clear and sharp output images. If used for web pages or screen display, 72 DPI or 96 DPI is usually sufficient. The specific DPI choice should be determined based on your final use and the requirements of the printing factory.
• Q: What business card sizes does the tool support for input? A: This tool supports custom input of any millimeter (mm) size for conversion, and also provides some internationally and domestically common standard business card size preset options, such as 90x54mm (Chinese standard), 85x54mm (credit card size), etc., to facilitate quick selection for users.
• Q: Will the conversion results be rounded? A: Yes, the calculated pixel (PX) values will be rounded to the nearest integer. This is to meet the actual design and development needs where pixels are usually integers, ensuring the usability of the values.
• Q: What are the practical uses of this business card size to PX tool? A: It is mainly used by designers to calculate the required pixel dimensions when creating business card print drafts, ensuring that the image resolution meets printing requirements; it can also be used by UI/UX designers to simulate the display effect of business cards at different screen resolutions; or in any scenario where physical dimensions need to be converted to digital pixel dimensions.

Notes

• Please ensure that the entered DPI value and business card dimensions (millimeters mm) are correct. Incorrect input will lead to inaccurate conversion results.
• The conversion result is a pixel (PX) value, which represents the number of "dots" at a specific DPI. The final physical print size and display effect are still determined by DPI, printing equipment, and monitor.
• For professional printing projects, it is strongly recommended that you confirm with the printing factory their recommended DPI, specific business card size specifications, and whether bleed (Bleed) needs to be reserved, to ensure that the design draft fully meets printing requirements.
• The conversion results provided by this tool are for reference only. In actual design, please pay attention to the adaptability of image content and proportion.

International Standards and Common Specifications for Business Card Sizes

As an important medium for business communication, business cards have different size standards and common specifications around the world. Understanding these differences is particularly important for international business and design. This tool supports custom size input, but you can also refer to the following common standards:

• Mainland China/Hong Kong: 90mm × 54mm is the most common standard size.
• Most of Europe: 85mm × 55mm is a widely adopted standard.
• United States/Canada: 3.5 inches × 2 inches (approx. 88.9mm × 50.8mm) is the standard size.
• Japan: 91mm × 55mm is more popular, often called "Meishi-ban".
• Credit Card Size: 85.60mm × 53.98mm, often used for VIP cards or special business cards.

The flexibility of this tool allows you to easily handle various international standards, ensuring that your business card design can adapt to global business needs.

DPI vs. PPI: A Detailed Explanation

In the field of images and printing, DPI (Dots Per Inch) and PPI (Pixels Per Inch) are two closely related but slightly different concepts concerning resolution, which are often confused. Understanding their differences helps to more accurately convert business card dimensions to pixels.

• DPI (Dots Per Inch): "Dots per inch" is mainly used to measure the resolution of physical printing devices (such as printers). It refers to the number of ink dots a printer can print per inch of length. The higher the DPI value, the richer the details and finer the quality of the printed image.
• PPI (Pixels Per Inch): "Pixels per inch" is mainly used to measure the screen resolution of digital images. It refers to the number of pixels contained in one inch of length on a display. The higher the PPI value, the clearer the image displayed on the screen and the greater the pixel density.

When you use the business card size to PX tool, the input DPI usually refers to the "target resolution" you want the image to achieve when printed or digitally output. For printing purposes, we usually refer to it directly as DPI; for purely digital display, understanding it as PPI would be more accurate. Regardless of the name, the core is to calculate the total number of pixels corresponding to the millimeter dimensions through a number of dots/pixels per inch.
