Video Graphics Array.
A standard resolution (size) for camera sensors, displays, photos, and videos. VGA size is 640 pixels wide by 480 pixels tall (or vice-versa in portrait orientation).
VGA is larger than CIF, QCIF, and QVGA, but smaller than 1 megapixel. (VGA is equivalent to 0.3 megapixel.)
For still photos, VGA is relatively small and low-resolution. For video, VGA is equivalent to standard-definition television.
