Why Sensor Size Matters
If there's a single factor that predicts the quality of the photos you'll get from a camera, a single letter grade that lets you compare cameras, it's this: the sensor size.
(David Pogue, “Help Crack the Sensor-Size Code”)
Using our sensor size calculator, you can easily convert the unfriendly measurements that digital camera manufacturers supply (like ratios or millimeters per side) to a simple diagonal measurement in inches. The larger this measurement, the higher quality of photos you're likely to get from the camera.
To save you time, you can also look up best-selling cameras here and compare their sensor sizes without having to find and calculate them yourself.
