Why a Smartphone’s Megapixels Don’t Matter As Much As You Think

It’s about quality over quantity

If you’ve ever purchased a new camera or smartphone, you’ve probably heard the term “megapixel.” Basically, it’s a way to quickly describe a camera’s resolution based on the number of pixels it’s capable of capturing.

One megapixel refers to one million pixels, which are small squares of information that combine to make up an image. So, if a camera has a resolution of eight megapixels, it would be able to capture images with about eight million tiny squares of information per inch, as’s photo expert explains.

Most smartphone brands usually refer to their device’s megapixel count when discussing their photo quality — and newer phone models typically come with improved cameras that feature more megapixels. For example, the cameras on Samsung’s Galaxy S5 and Galaxy S6 both come with 16-megapixel sensors, while the Galaxy S4 featured a 13-megapixel camera. The iPhone 6s and 6s Plus both have 12-megapixel cameras, an improvement over older iPhones’ 8 megapixels


The way megapixels are touted by brands in their ads can lead some people to believe that a higher number of megapixels always means better photos. That may be true sometimes. But it isn’t always the case, according to Nikhil Bhogal, the founder and CTO of June, which makes a smart oven of the same name. Before cofounding June, Bhogal was a software engineer at Apple where he worked on camera technology for the iPhone.

Bhogal says pixel quality matters more than the actual number of pixels in a camera sensor, especially when it comes to smartphone cameras. “Even in a tiny picture, you can pack in a lot of good quality information,” says Bhogal. “You don’t have to take a 40-megapixel picture to have that much information.”

So what does it mean to increase the quality of pixels on a camera sensor? In some instances, it can mean making individual pixels larger rather than cramming more pixels into a given space. That could improve photo quality, but it won’t increase the number of megapixels
