Image Resolution
Convert pixel dimensions into total pixels, megapixels and a standard aspect label.
About Image Resolution
Multiplying pixel width by height gives the total pixel count, which is then expressed in megapixels and matched to a common aspect ratio. Megapixels and aspect ratios describe how much detail and what shape an image will have, which drives file size and how it prints.
Formula
Image Resolution
Megapixels = width x height / 1,000,000; aspect = width / height
- megapixel
- One million pixels of image data
Worked example
With the default values below, Image Resolution returns Total Pixels of 24,000,000. 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 Image Resolution calculated?
Megapixels = width x height / 1,000,000; aspect = width / height Multiplying pixel width by height gives the total pixel count, which is then expressed in megapixels and matched to a common aspect ratio.
Why does Image Resolution matter?
Megapixels and aspect ratios describe how much detail and what shape an image will have, which drives file size and how it prints.
What values do I need to enter?
This calculator takes 2 inputs: Width, 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.
