Screen Resolution Simulator – Test Website Resolution Online
Modern websites must adapt to a wide range of devices, from smartphones to large desktop monitors. Our screen resolution simulator allows you to test how a webpage appears across different screen sizes. By simulating multiple resolutions, you can verify whether a website layout responds correctly to various device dimensions.
This website screen resolution tester loads the selected webpage and renders it inside a simulated viewport. Developers and designers use this tool to ensure that responsive layouts display correctly on mobile devices, tablets, and desktops.
What Is a Screen Resolution Simulator
A screen resolution simulator is a testing tool that displays a webpage inside different viewport sizes. Instead of manually resizing your browser window, the tool automatically renders the webpage using predefined device resolutions.
This helps designers preview how a website appears on devices with different screen widths and heights.
