Pixels and inches cannot be directly converted, which is related to the image resolution. If it is 72 pixels/inch, 220px is 220÷72=3. 06 inches, 50÷72=0. 69 inches. That's three. 06 inches times 0. 69-inch photo.

The actual print size of the picture is determined by the pixel and resolution of the electronic picture. Pixel refers to the small color points that make up the picture, and resolution refers to the number of pixels per inch, which can be regarded as the distribution density of these small color points. When the pixels are the same, the higher the resolution, the larger the pixels per inch, the smaller the actual printing size and the clearer the image.
