iPhone Display Specs
The iPhone display specs can be a bit overwhelming, but let's break it down. Apple offers a range of display sizes, from 4 to 6.7 inches.
The smallest display size is 4 inches, with a resolution of 1136 x 640 pixels and a pixel density of 326 PPI. This display type is used in older iPhone models.

Here's a summary of the display specs for different iPhone models:
The iPhone 14, for example, has a 6.1-inch display with a resolution of 1170 x 2532 pixels and a pixel density of 460 PPI. Its viewport size is 390 x 844 pixels, and its pixel ratio is 3.

Camera and File Sizes
The file size of iPhone camera photos can vary depending on several factors, but here's a general rule to keep in mind.
Photos taken with the main lens, which has a resolution of 24 MP, typically have a file size of around 6 MB to 8 MB per image.
For comparison, 12 MP photos taken with the wide-angle and telephoto lenses have generally smaller file sizes, ranging from 2 MB to 4 MB per image.
Here's a quick summary of the estimated file sizes for iPhone camera lenses:
- Main lens (24 MP): 6 MB to 8 MB per image
- Wide-angle and telephoto lenses (12 MP): 2 MB to 4 MB per image
Why iPhone Numbers Matter

The higher the number of megapixels on an iPhone, the clearer the photos will be.
A 12-megapixel camera, like the one found in the iPhone 7, can take high-quality photos in good lighting conditions.
The iPhone 12 Pro has a 48-megapixel camera, which is a significant improvement over the 12-megapixel camera in the iPhone 7.
A higher megapixel count means more detailed images, but it's not the only factor that determines image quality.
The iPhone 11 Pro has a 12-megapixel camera, but its image quality is still impressive, thanks to its advanced software and processing capabilities.
The number of megapixels in an iPhone's camera is just one factor to consider when evaluating image quality.
In general, a higher megapixel count is associated with a higher price point for an iPhone.
