Sensor sizes are expressed in inches notation because at the time of the popularization of digital image sensors they were used to replace [[video camera tube]]s. The common 1" outside diameter circular video camera tubes have a rectangular photo sensitive area about 16&nbsp;mm on the diagonal, so a digital sensor with a 16&nbsp;mm diagonal size is a 1" video tube equivalent. The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor. Current digital image sensor size descriptors are the video camera tube equivalency size, not the actual size of the sensor. For example, a 1" sensor has a diagonal measurement of 16&nbsp;mm.<ref>{{cite web|title=Making (some) sense out of sensor sizes|url=http://www.dpreview.com/news/2002/10/7/sensorsizes|work=Digital Photography Review|access-date=29 June 2012|author=Staff|date=7 October 2002}}</ref><ref>{{cite web|title=Image Sensor Format |url=http://www.spotimaging.com/resources/glossary/image-sensor-format.php |archive-url=https://web.archive.org/web/20150326051941/http://www.spotimaging.com/resources/glossary/image-sensor-format.php |url-status=dead |archive-date=26 March 2015 |work=Imaging Glossary Terms and Definitions |publisher=SPOT IMAGING SOLUTIONS |access-date=3 June 2015 |author=Staff }}</ref>
