Learn how to convert design sizes from centimeters or inches to pixels for optimal printing

Updated over 3 months ago

This article provides a guide on converting design sizes from centimeters or inches to pixels for optimal printing results. It explains the importance of image resolution and provides practical conversion methods and examples.


Understanding Resolution

Before converting your design's dimensions, it's crucial to understand image resolution. Resolution determines the clarity and sharpness of your printed product. It's measured in dots per inch (DPI), indicating how many tiny dots of ink fit into a square inch.

For high-quality prints, aim for a resolution of at least 150 DPI. However, for the best results, we recommend a resolution of 300 DPI. This ensures your designs are printed with exceptional detail and clarity.

Conversion Methods

To convert centimeters or inches to pixels, you can utilize various online tools or apply a straightforward conversion equation.

Online Conversion Tools:

Several user-friendly online converters can simplify the process. Here are two popular options:

Conversion Equation:

For those who prefer a more hands-on approach, the following equation can be used to convert millimeters to pixels:

Pixel = Millimeter * (Resolution / 25.4)

For instance, with a resolution of 300 DPI, the equation becomes:

Pixel = Millimeter * (300 dpi / 25.4) = Millimeter * 11.81

Conversion Example:

Let's say you have a design that is 10 centimeters wide. To convert this to pixels at 150 DPI, the online converter would yield approximately 590 pixels. At 300 DPI, the same 10 centimeters would translate to about 1180 pixels.
