So if you have a 12 megapixel iPhone and you want an excellent quality professional-looking print at 300 PPI, the biggest you can print your photo is 14.29 inches by 9.49 inches. But if you’re willing to print at 150 PPI, you’ll be able to have a much larger photo .
Standard (or postcard) size ( 4 x 6 in.); Square sizes (8 x 8, 10 x 10 and 12 x 12 in.) and rectangular sizes (8 x 12 and 11 x 14 in.), which are ideal for portraits; Panoramic sizes (width of 4, 4.5 or 5 in.) to capture all the glory of your landscape shots.

The dimensions of a digital photo are expressed in terms of its pixels, for instance “800 x 600” or “1520 x 1280” where the first number is the width of the photo and the second number the height of the photo . The term pixel is also used for the image sensor elements on a digital camera.
As a general rule of thumb, a normal photo taken on a recent iPhone model (say, iPhone 6s and newer) has plenty of image size (they are natively 4032 x 3024 pixels) to create a very good quality print at 20 x 26 inches.
The iPhone takes photos with an aspect ratio of 4:3. Well, apparently that is the preferred ratio in still photography because it captures more pixels in the picture and is the preferred format for print, etc. If they were to use a 16:9 ratio for photos , then you wouldn’t be able to capture as much in each shot.
How Bright Is Your Screen? One really common problem with printed images is that, compared to the photo on screen, they look really drab and dark. This is because screens and printed images are fundamentally different things: a screen displays images by directly emitting light while a print reflects the ambient light.
Most Popular Picture Frame Sizes 4×6 photos are the standard photo size and the most common for 35mm photography . The next size up from 4×6 is a 5×7 photo print . 8×10 photos are larger than 4×6 and 5×7 so they are typically used for group photos or portraits. 16×20 sized prints are considered small posters.
