Frequently Asked Questions
What is the relationship between pixels and physical size?
The physical size of a pixel depends on the screen resolution and display size. PPI (pixels per inch) defines the density. A 1920x1080 display at 24 inches has about 92 PPI.
What resolution do I need for printing?
For high-quality prints, 300 DPI (dots per inch) is standard. A 10x15 cm photo at 300 DPI needs about 1,181 x 1,772 pixels. For posters viewed from distance, 150 DPI may suffice.
What is the Pixel Calculator?
The pixel calculator converts between pixels, centimetres, inches and points at various screen resolutions.
How does the Pixel Calculator work?
Enter the size in pixels (or cm/inches) and the resolution (DPI/PPI). The calculator computes the physical size. Useful for print preparation, web design and image editing.
Key Data and Facts
Standard screen resolution: 72-96 PPI. Print quality: 300 DPI. Conversion: pixels = cm * DPI / 2.54. 1 inch = 2.54 cm = 72 points (pt).
