Megapixels Calculator

Translate pixel dimensions into megapixels in seconds. Enter the width and height to see the sensor or file resolution expressed in millions of pixels—perfect for comparing cameras, planning large prints, or sizing digital assets.

Horizontal pixel dimension of the photo or render. Check your image properties or camera spec sheet.
Vertical pixel dimension. Use the full-resolution number, not the cropped preview size.

Megapixel count alone does not determine image quality.

Examples

  • 6000 × 4000 ⇒ 24 MP
  • 8256 × 5504 ⇒ 45.4 MP

FAQ

What is a megapixel?

One megapixel equals one million pixels.

Does higher megapixels mean better quality?

Not always; sensor size and lens quality also matter.

Can I reverse the calculation?

Multiply megapixels by 1,000,000 to get total pixels, then factor the number into width × height combinations that match your aspect ratio.

How does cropping affect megapixels?

Cropping removes pixels, so the resulting width and height produce a lower megapixel count even if the original file was larger.

Additional Information

  • Results are shown in megapixels. Multiply by one million to convert back to total pixel count.
  • Divide the pixel dimensions by 300 to estimate the maximum high-quality print size in inches.
