Overview and Dimensions

iPhone 8 was released by Apple on September 22, 2017 and is powered by iOS OS. By default, the device is shipped with a web browser — Safari for iOS. Device dimensions are 67.3 × 138.4 × 7.3 millimeters (2.65 × 5.45 × 0.29 inches) ¹. The device weighs 148 g.

iPhone 8 has a medium-sized Retina IPS LCD display with a 4.7-inch screen (60.9 cm², 16:9 aspect ratio), and an approximate 65.4% screen-to-body ratio. The display is a touch screen, meaning that it supports touch events - interactions using a finger or stylus.

Screen size, Viewport, CSS Pixel Ratio

iPhone 8 has a 4.7-inch screen with a screen size (resolution): 750px × 1334px, 375px × 667px viewport¹, and a CSS Pixel Ratio of 2.

Key points for development and testing on iPhone 8

Before you start web development or testing, check that the web application supports a responsive viewport by using a viewport meta tag: <meta name="viewport" content="width=device-width">.
You can inspect this tag in the head section of an HTML document on iPhone 8 right in the Blisk app. If this viewport tag is missing, the web application will not be responsive and will overflow the screen, hiding the content from users and leading to a bad user experience.

The form factor of the device represents its primary orientation as a portrait. Landscape orientation is popular on iPhone 8 as well and should be seriously considered when you develop or test web applications on any mobile.

You also need to consider that the users will manipulate your web application on iPhone 8 with a finger and stylus because this device has a touch screen that supports touch events. It is important to remember, that users may interact with multiple fingers (multi-touch) and gestures: single tap, multi-tap, swipe, pinch, stretch, zoom, etc. The users are highly likely to use gestures on small touch screens because of seamless interaction and great user experience.
