Online Sensor Size Calculators and Comparison Charts

A camera’s sensor size is a very good predictor of how good its image quality is, but understanding and comparing the sensors sizes isn’t very easy. While televisions and computer monitors are usually measured by diagonal length, sensors sizes are listed with its two dimensions in millimeters. Back in 2008, David Pogue of the New York Times wrote an article about this issue, calling for someone to develop an online tool for converting confusing sensor measurements into the diagonal length of the sensor in inches. Within three hours two new websites were born: Sensor-Size and Sensor Size Calculator.
