List of common resolutions

For the table below, SAR (storage aspect ratio) is based solely on pixel count. It does not take into account PAR (pixel aspect ratio, pixels may be non-square) and thus the DAR (display aspect ratio, the aspect ratio of the actual image that is displayed) may differ.

A list of standard designated VGA display resolutions, commonly used in computing and computer monitors, can also be found at Graphics display resolution.

For television, the display aspect ratio (DAR) is shown, not the storage aspect ratio (SAR); analog television does not have well-defined pixels, while several digital television standards have non-square pixels.

The below distinguish SAR (aspect ratio of pixel dimensions), DAR (aspect ratio of displayed image dimensions), and the corresponding PAR (aspect ratio of individual pixels), though it currently contains some errors (inconsistencies), as flagged.
