How to Calculate Megapixels

Megapixels seem to be the point at which a digital camera's quality is based on. The higher the megapixel, the better quality the photo production will be. But how do we figure out how many megapixels a camera has, other than its advertisement saying so? Follow these steps to find out.
Instructions
Difficulty: Moderately Easy
1.
We must first fully understand what a megapixel is before we can calculate it. Digital cameras take images that have small dots or picture elements, also known as pixels. The pixels are arranged along horizontal and vertical axis to create the picture.
2.
A megapixel is an estimated number found by multiplying the horizontal and vertical pixels with one another.
3.
The image size will determine the megapixel number. For instance, a camera holding a 5-megapixel rating has 2,592 horizontal pixels and 1,944 vertical pixels.
