The iPhone camera is capable of recording in two aspect ratios: 4:3 and 16:9. The 4:3 aspect ratio uses the full megapixels, while 16:9 is cropped for a wider view. We’ll show you how to switch.
The difference between 4:3 and 16:9 is the width of the photo. However, it’s not that simple on the iPhone. Shooting in 16:9 doesn’t necessarily mean you’ll be captured more from the sides of the shot. Depending on your iPhone cameras, you may just crop the 4:3 photo.

Regardless, it’s simple to switch between the two aspect ratios. First, open the camera app on your iPhone.
Now tap on the arrow at the top of the screen.
Some controls will slide up from the bottom of the screen. Tap the “4:3″ or 16:9” button.
Now you can choose “16:9”, “Square” or “4:3”.
That’s all about it! Again, keep in mind that 16:9 aspect ratio is generally lower resolution than 4:3, since you’re cropping the shot. If you want to always get the most out of your camera hardware, shoot in 4:3.
