Print Size Calculator

The formula for converting inches to pixels depends on the resolution, typically measured in pixels per inch (PPI) or dots per inch (DPI) for digital screens and print.

The formula is:

Pixels=Inches×DPI\text{Pixels} = \text{Inches} \times \text{DPI}Pixels=Inches×DPI

Follow the Steps:

1. Determine the resolution (PPI or DPI) of the device or medium. Common values include:
   • 72 PPI for low-resolution screens (older standard).
   • 96 PPI for modern screens (default for Windows).
   • 300 PPI or higher for high-quality prints.
2. Multiply the number of inches by the PPI.

Example:

If an image is 5 inches wide and the resolution is 96 DPI:Pixels=5×96=480 pixels\text{Pixels} = 5 \times 96 = 480 \, \text{pixels}Pixels=5×96=480pixels

How to Use the Pixels to Inches Converter

Before you use the converter, it’s helpful to understand a few basics about the relationship between pixels, inches, and DPI, depending on whether you’re working with web content, print media, or determining device dimensions.

Working with Web

For web design, screen resolution is often set at 96 PPI, as recommended by the World Wide Web Consortium (W3C). While this standard is suitable for digital screens, a resolution of 96 PPI is not ideal for printing high-quality images.

Working with Print Media

If you’re designing for print, 300 DPI (dots per inch) is the industry standard for high-quality images. DPI represents the number of printed dots per inch, which corresponds to the image’s resolution. For example:

• An image with 300 DPI contains 300 pixels per inch.
• Printing an 8″ x 10″ image at 72 PPI results in a blurry output compared to printing the same image at 300 PPI, which will look much sharper and more professional.

Device Dimensions

To calculate the dimensions of a device, such as a monitor or a smartphone screen, you’ll need its DPI and pixel dimensions. For example, a screen with a resolution of 1080 x 2340 pixels and a DPI of 300 can be converted into inches using the formula:Inches=PixelsDPI\text{Inches} = \frac{\text{Pixels}}{\text{DPI}}Inches=DPIPixels​

Steps to Use the Converter

1. Enter the DPI: Default is set to 300.
2. Input the pixel value you wish to convert into inches.
3. Press “Convert” to calculate the equivalent dimension in inches.

Pixels to Centimeters Conversion Table (300 DPI)

To convert pixels (px) to centimeters (cm) at 300 DPI, the formula is:Centimeters=PixelsDPI×2.54\text{Centimeters} = \frac{\text{Pixels}}{\text{DPI}} \times 2.54Centimeters=DPIPixels​×2.54

Formula for Custom Values:

If your pixel value isn’t in the table, use this formula:Centimeters=Pixels300×2.54\text{Centimeters} = \frac{\text{Pixels}}{300} \times 2.54Centimeters=300Pixels​×2.54

This table and formula help easily convert pixel dimensions into centimeters, particularly for high-quality print materials at 300 DPI.
