Centimeter to Pixel Converter (CM to PX) – Instant & Accurate
Our online CM to PX converter is a professional-grade utility designed for graphic designers, web developers, and print specialists. Whether you are preparing a layout for a website or setting up a high-resolution document for print, calculating the exact pixel dimensions is crucial for maintaining image quality and clarity.
Why Use Our Converter?
Unlike basic calculators, our tool allows for custom DPI/PPI settings. This is vital because the number of pixels in a centimeter changes based on the resolution:
-
Web Design Standard (96 DPI): Ideal for digital interfaces and standard monitors.
-
Legacy Screen Standard (72 DPI): Still used in some digital display calculations.
-
Professional Printing (300 DPI): The industry standard for brochures, posters, and physical media to prevent pixelation.
How to Use the CM to PX Converter
Follow these three simple steps to get the most accurate dimensions for your digital or print projects:
-
Enter your Resolution (DPI/PPI): Input the resolution of your project. For standard web images, use 96. For high-quality printing, use 300.
-
Input your Centimeters: Enter the physical size you want to convert in the “Centimeters” field.
-
Get Instant Results: The tool will automatically calculate the equivalent pixels. You can then copy the value for use in Photoshop, CSS, or Canva.
Need to go the other way? If you already have a pixel measurement and need to find the physical size, use our Pixel to Centimeter Converter for the same high-precision results.
Accurate Results for Every Project
This tool uses the precise mathematical ratio based on the international inch (2.54 cm). By inputting your specific dots per inch (DPI), you ensure that your digital assets translate perfectly to the physical world. This is especially useful for calculating A4 paper sizes, social media assets, and CSS layout dimensions.
How to Convert Centimeters to Pixels?
Converting cm to px isn’t as simple as a fixed number because pixels are relative to the resolution of the screen or printer, known as DPI (Dots Per Inch) or PPI (Pixels Per Inch).
The Standard Formula:
Pixels = Centimeters × (DPI / 2.54)
-
Why 2.54? Because 1 inch is exactly 2.54 centimeters. (Source)
-
For Web Design: Most browsers use a default of 96 DPI. (1 cm ≈ 38 px)
-
For High-Quality Print: Professionals use 300 DPI. (1 cm ≈ 118 px)

Why is DPI/PPI Important?
If you are designing a business card (8.5cm x 5.5cm), calculating the pixels at 72 DPI will result in a blurry print. By switching to 300 DPI in our converter, you ensure your digital file has enough “pixel density” to look sharp when physically printed.
Frequently Asked Questions
How many pixels are in 1 cm?
At the standard web resolution of 96 DPI, 1 centimeter is equal to 37.795 pixels. If you are designing for high-quality print at 300 DPI, 1 centimeter is equal to 118.11 pixels.
What is the formula to convert cm to px?
The mathematical formula to convert centimeters to pixels is: Pixels = Centimeters * (DPI / 2.54). Since there are 2.54 centimeters in an inch, we divide the DPI (dots per inch) by 2.54 to find the pixels per centimeter.
Is a pixel always the same size in centimeters?
No, the physical size of a pixel is determined by the PPI (Pixels Per Inch) or DPI. On a high-resolution screen (like a Retina display), pixels are much smaller than on a standard monitor, which is why 1 cm contains more pixels at higher resolutions.
What DPI should I use for web vs. print?
For most digital screens and web projects, 96 DPI is the standard. For professional printing, 300 DPI is recommended to ensure the image remains sharp and clear.
