Megapixel Calculator

Calculate megapixels from image dimensions or find what dimensions you get from a certain megapixel count.

Megapixels = (Width × Height) / 1,000,000

24MP camera at 3:2 = 6000×4000 pixels. More megapixels = larger prints and more crop flexibility.

How many megapixels do I need?

12MP: social media, 4×6 prints. 24MP: large prints, cropping. 45MP+: commercial, heavy cropping. Most people need 12-24MP.

Does more megapixels mean better quality?

Not necessarily. Sensor size, lens quality, and ISO performance matter more. 12MP full-frame often beats 48MP phone sensor.
