A movie’s size is determined by a number of elements, including its length, resolution, and encoding. A movie is thought to take up anywhere from a third of a gigabyte to as much as seven.
According to TalkTalk Business, an approximate range of 700 megabytes to 1.5 gigabytes is needed to download the average movie. Between 250 and 500 megabytes of data are used to stream an hour of video.
On an iPad, streaming video consumes 2 gigabytes of data over six to twelve hours, or one-sixth to one-third of a gigabyte every hour of video.
Around 0.3 gigabytes of data are consumed to stream a video every hour at low quality, 0.7 gigabytes at medium level, 3 gigabytes at HD quality, and 7 gigabytes at Ultra HD quality.
