Screen size, Viewport & Pixel Ratio

Laptop-M has a 15.6-inch screen with a screen size (resolution): 1366px × 768px , 1366px × 768px viewport1, and a CSS Pixel Ratio of 1.

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.

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

Before you start web development or testing, check that the web application supports a responsive viewport by using a viewport meta tag:

You can inspect this tag in the head section of an HTML document on Laptop-M 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 Laptop-M as well and should be seriously considered when you develop or test web applications on any mobile.

You also need to consider that desktops are usually manipulated with a mouse, keyboard, and touchpad. To develop a high-quality web application, the developer should keep in mind the way the application responds to the actions of a user on hovers, clicks, drag and drop, focus events, etc. It has become a good practice to use mobile-like behaviors on desktops (e.g. swipe event on a slider). The majority of modern touchpads allow using multi-gestures on laptops and desktops.
