Sensor Resolution (Megapixels)
Convert a sensor's pixel width and height into megapixels and total pixels.
About Sensor Resolution (Megapixels)
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.
Formula
Sensor Resolution (Megapixels)
Megapixels = width x height / 1,000,000
- megapixels
- Millions of photosites on the sensor
Worked example
With the default values below, Sensor Resolution (Megapixels) returns Megapixels of 24.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Sensor Resolution (Megapixels) calculated?
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.
Why does Sensor Resolution (Megapixels) matter?
Resolution sets the ceiling on print size and cropping, though lens and sensor quality matter just as much.
What values do I need to enter?
