Before starting this topic, first, we have to know what Pixel density is.
Pixel density (PPI) Refers to the concentration of pixels on a particular display, measured in pixels per inch (PPI). Pixel density is calculated by dividing the diagonal pixel resolution of a display by its diagonal size.
Let’s discuss in brief,
What is the pixel density?
How to calculate Pixel density?
You can calculate PPI in multiple ways. The most common one is to calculate it from the diagonal screen size (in inches or cm) and the number of pixels along the vertical and horizontal edge of the display.
d? = v(w² + h²)Where,
PPI = d?/d?Where,
What is DPI (Display per inch)?
Difference between Pixels and DPI (Dots per Inch)?
What Is Retina Display?
So, bottom line, a high-resolution photo is an image with high-quality pixels, saved in either a non-lossy file format or a low compression (high quality) JPEG, that can supply the desired PPI (usually 300) for the intended print size.
