Questions: What is the iPhone screen resolution? What is the iPad screen resolution?
If you are developing an app or a web pages for iPhone or iPad users, you need to know how many pixels you have available on the screen.
iPhone 5 Screen Resolution
The iPhone 5 Screen Resolution is 1136 x 640. The 5th generation iPod Touch also has a resolution of 1136 x 640. These iPhones have the Retina display.
The iPhone 4, iPhone 4s, and 4th generation iPod touch have a screen resolution of 960 x 640.
The original iPhone through the iPhone 3GS, as well as the first three generations of iPod Touch, all had a screen resolution of 480 x 320.
iPad Screen Resolution
The iPad screen resolution for the 3rd and 4th generation iPads is 2048 x 1536. These iPads have the Retina display.
The iPad screen resolution for the 1st and 2nd generation iPads, as well as the iPad Mini is 1024 x 768.
How do I ensure that my web pages will work with all iPhones?
I would say that you should only develop web pages to support the iPhone 4 through the iPhone 5 (and the iPhone 6 and iPhone 7, when ever they come out 🙂 ). The overwhelming majority of iPhone users will have a iPhone or greater. Plus, the iPhone 3 screen resolution is so narrow that ensuring that all of your content at ads will show on it correct just isn’t worth the hassle in my opinion.
