How do pixels affect image quality?

Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image. Images with lower resolutions have fewer pixels, and if those few pixels are too large (usually when an image is stretched), they can become visible like the image below.

Where are pixel dimensions used?

Does bigger image size mean better quality?

The higher the PPI, the higher the image resolution and this also means the higher the image quality. Dot pitch is a measure used to determine the sharpness of an image. This is measured in millimeters (mm) and a smaller number means a sharper image. When you have closer spaced pixels, the image will look much sharper.

Images with more pixels may produce more detail at a given printed size, but they require more disk space to store and may be slower to edit and print. Image resolution thus becomes a compromise between image quality (capturing all the data you need) and file size.
