How to use Megapixel Aspects

totalPixels = MP × 1,000,000; width = √(totalPixels × (W/(W+H))); height = width × (H/W) normalized

A megapixel is one million pixels. The same megapixel count can map to different width and height depending on the aspect ratio.

Cameras commonly use 3:2 (DSLR/mirrorless), 4:3 (micro four thirds, phones), and 16:9 (video).

Does more megapixels mean better quality?

Not always; sensor size, lens, and pixel quality matter as much as the count.

Why do phones list 4:3 but shoot 16:9 video?

Video crops the sensor to 16:9, which is why stills and video resolutions differ.

How do I get exact dimensions?

Use the calculator: it solves width × height = total pixels under your chosen ratio.
