To calculate DPI from centimeters, divide the number of pixels by the width (or height) in centimeters and then multiply the result by 2.54. This will give you the image’s resolution in DPI.

Enter any 2 values to calculate the missing variable
The Cm to DPI Calculator is a simple tool that converts centimeters to DPI, ensuring accurate resolution for your images. By inputting your image’s dimensions in cm and pixels, you can easily calculate the DPI needed for high-quality prints or displays.
Formula:
To convert centimeters (cm) to dots per inch (DPI), you can use the formula:
Where:
- P is the number of pixels (image width or height in pixels)
- W is the width or height in centimeters (depending on the direction you are calculating for)
- 2.54 is the conversion factor from centimeters to inches.
| Variable | Description |
|---|---|
| DPI | Dots per inch (resolution) |
| P | Pixels (either width or height in pixels) |
| W | Width or height in centimeters |
Example Calculation:
Let’s assume you have an image with a width of 1200 pixels and a physical width of 10 cm.
Using the formula:
So, the image has a resolution of 304.8 DPI.
Step-by-Step Calculation:
| Step | Calculation | Result |
|---|---|---|
| 1 | Divide Pixels by Width (in cm) | |
| 2 | Multiply by 2.54 (conversion factor to inches) | DPI |
What is Cm to Dpi Calculator ?
The Cm to DPI Calculator is a tool used to convert dimensions in centimeters to DPI (Dots Per Inch), which is crucial for understanding image resolution.
For example, to convert 300 DPI to cm, you can rearrange the formula to find the corresponding size in centimeters for a given DPI.
Tools like a cm to DPI calculator online or pixels to DPI converter can simplify this process, especially for tasks like finding out the DPI of an image based on its dimensions, such as 300px in cm. These calculators are also useful for determining the correct resolution for printing images at a specific DPI, like ensuring a 6×3 cm image is at 200 DPI.
For more complex conversions, like converting 600 DPI to pixels or working with file sizes (KB), the PPI to DPI converter helps switch between pixels per inch and dots per inch, ensuring accurate image resolutions for different media and formats.
