The Cm to Pixel Calculator is a useful tool for converting measurements from centimeters (cm) into pixels (px), an essential function in digital design, printing, and image editing. This conversion requires knowing the dots per inch (DPI) value, which defines the resolution of a display or printed medium. By converting physical dimensions to pixels, designers and developers can accurately scale images, graphics, and layouts.
Why Is This Calculator Useful?
- Accuracy in Digital Design: Ensures precise alignment of digital and physical dimensions.
- Compatibility Across Devices: Helps optimize visuals for screens with varying resolutions.
- Ease of Use: Provides instant conversion without manual calculations.
Formula of Cm To Pixel Calculator
The formula for converting centimeters to pixels is:
Pixels = Centimeters × DPI ÷ 2.54
Where:
- Pixels represent the size in the digital format.
- Centimeters is the physical measurement of the object.
- DPI (dots per inch) indicates the resolution of the display or print medium.
- 2.54 is the conversion factor from inches to centimeters.
Precomputed Table for Common DPI Values
The following table provides precomputed pixel values for standard DPI settings and common centimeter measurements:
| Centimeters (cm) | DPI: 72 | DPI: 96 | DPI: 150 | DPI: 300 |
|---|---|---|---|---|
| 1.0 | 28.35 | 37.80 | 59.06 | 118.11 |
| 5.0 | 141.73 | 189.00 | 295.28 | 590.55 |
| 10.0 | 283.46 | 378.00 | 590.55 | 1181.10 |
| 20.0 | 566.93 | 756.00 | 1181.10 | 2362.20 |
| 50.0 | 1417.32 | 1890.00 | 2952.76 | 5905.50 |
This table can assist users in quickly determining pixel values for standard resolutions.
Example of Cm To Pixel Calculator
Problem:
You are designing an image for a 10 cm wide banner to be printed at 300 DPI. How many pixels wide should the banner be?
Solution:
Using the formula:
Pixels = Centimeters × DPI ÷ 2.54
Substitute the values:
Pixels = 10 × 300 ÷ 2.54 = 1181.10
Answer:
The banner should be 1181 pixels wide.
Most Common FAQs
DPI stands for dots per inch and measures the resolution of an image or display. Higher DPI values result in sharper images, making DPI essential for printing and high-quality digital designs.
Yes, simply enter the desired DPI value into the formula to get the corresponding pixel conversion.
Yes, screen displays also use DPI, though it is often referred to as PPI (pixels per inch). This conversion helps ensure proper scaling and image quality on different screens.
