How it's calculated

Formula

Megapixels = \dfrac{Width_{px} \times Height_{px}}{1{,}000{,}000}

Width_{px}, Height_{px}: — Image resolution in pixels

What is the Megapixel Calculator?

A megapixel is one million pixels — camera sensors and image resolutions are commonly advertised in megapixels, which is just the total pixel count divided by a million.

How to use it

1 Enter the image or sensor's width in pixels.
2 Enter the height in pixels.

Worked examples

Frequently asked questions

Do more megapixels mean better photos?

Not necessarily — sensor size, lens quality and processing matter at least as much as raw pixel count for real-world image quality.
