Screen Size

Screen resolution vs browser viewport

Your screen resolution is the total number of pixels available on your display, such as 1920 × 1080 or 3840 × 2160. Your browser viewport is different: it is the visible website area inside the browser window after toolbars, tabs, scrollbars, zoom, and operating system scaling are applied.

Responsive Design

Useful for designers and developers

When building responsive websites, the viewport size and device pixel ratio are often more important than the raw monitor resolution. This checker helps you understand what CSS media queries, layouts, screenshots, and browser tests actually see on your current device.

Understanding display details

A modern screen can report several different measurements. File Gulp shows the most useful values together so you can diagnose layout issues, compare devices, and share accurate display specs.

Screen Resolution: The full width and height reported by your display, measured in screen pixels.
Viewport Size: The visible browser area available to a website, measured in CSS pixels.
Device Pixel Ratio: The relationship between physical device pixels and CSS pixels. High-DPI or Retina displays usually report a DPR greater than 1.
Available Screen: The usable area after the operating system reserves space for elements like taskbars, docks, or menu bars.
Aspect Ratio: The proportional shape of your display, such as 16:9, 16:10, 21:9, or another ultrawide format.
