Convert a sensor's pixel width and height into megapixels and total pixels.
Multiplying the two pixel dimensions gives the total photosites, divided by one million to express resolution in megapixels. Resolution sets the ceiling on print size and cropping, though lens and sensor quality matter just as much.
Sensor Resolution (Megapixels)
Megapixels = width x height / 1,000,000
Megapixels = width x height / 1,000,000 Multiplying the two pixel dimensions gives the total photosites, divided by one million to express resolution in megapixels.
Resolution sets the ceiling on print size and cropping, though lens and sensor quality matter just as much.
This calculator takes 2 inputs: Sensor pixel width, Sensor pixel height. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
