Screen size, Viewport, CSS Pixel Ratio

iPhone 8 Plus has a 5.5-inch screen with a screen size (resolution): 1080px × 1920px, 414px × 736px viewport1, and a CSS Pixel Ratio of 2.6.

1 Property is displayed as width × height.

Screen size (resolution) is the number of physical pixels present on a screen.

Viewport or Viewport size is the number of software pixels (CSS pixels) present on a screen. Usually, viewport size displays as viewport width in pixels to viewport height in pixels.

Device Pixel Ratio (DPR) or CSS Pixel Ratio is the ratio between the physical pixels (screen size or resolution) and CSS pixels (viewport).
Depending on device specification, one CSS pixel can equal one or mode physical pixels. Modern devices have screens with high pixel density resulting in the difference between
screen size (resolution) and viewport.

Summary:

Screen Size (Resolution) = Viewport size × Device Pixel Ratio.

Viewport size = Screen Size (Resolution) / Device Pixel Ratio.

CSS Pixel Ratio = Screen Size (Resolution) / Viewport size.

Key points for development and testing on iPhone 8 Plus

Before you start web development or testing, check that the web application supports a responsive viewport by using a viewport meta tag:
&ltmeta name="viewport" content="width=device-width">.

You can inspect this tag in the head section of an HTML document on iPhone 8 Plus 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 Plus 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 Plus 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.
