Preview how a website looks on different screen sizes, from small laptops to large monitors.
Enter a URL
Pick a screen resolution and see your page inside a frame of that size. It is a quick check of how your layout behaves on common screen widths. Some sites block being shown inside frames, in which case test them with your browser's device mode instead.
Some sites forbid being shown inside a frame for security reasons. Use your browser's device mode (F12, then the phone icon) to test those sites.
Most visitors now browse on phones, so check widths around 360–430 pixels first, then laptops around 1366–1536 and large screens around 1920.
