Image megapixel calculator
Calculate megapixels from width and height.
How to use the Image megapixel calculator
What does the Image megapixel calculator do?
Calculate megapixels from width and height; It applies this page-specific rule: megapixels equal width × height divided by one million.
Which inputs does this calculator use?
To calculate megapixels from width and height, enter Width (px), Height (px); keep every value in the same example; select Calculate when the values are ready; Start with a familiar case covered by this rule - A 6000 by 4000 image contains 24 million pixels, or 24 megapixels - so the expected result can confirm the settings.
How should the calculator result be read?
For a result intended to calculate megapixels from width and height, a 6000 by 4000 image contains 24 million pixels, or 24 megapixels; read height (px) together with the original width (px) rather than as an isolated answer, and confirm that its units or structure match the intended use.
What calculation does this use?
When the goal is to calculate megapixels from width and height, megapixels equal width × height divided by one million.
Why might a real result differ?
When using the page to calculate megapixels from width and height, megapixels do not measure sharpness, compression quality, dynamic range, or file size.
Limits and accuracy
When using this calculator to calculate megapixels from width and height, megapixels do not measure sharpness, compression quality, dynamic range, or file size; the result is an estimate unless every source value is known; codecs, metadata, overhead, and variable bitrates can change an actual file; keep width (px) until the output has been checked in its intended destination. For a repeatable check when you need to calculate megapixels from width and height, record Width (px) alongside the final output and selected options. A known example using width (px) can confirm how the page will calculate megapixels from width and height.
