A Webpage Screen Resolution Simulator tool allows you to test how a website or web application appears on different screen sizes and resolutions. This is particularly useful for responsive design testing, ensuring your site looks good on desktops, tablets, and mobile devices.
Here are some popular tools (both online and browser-based) to simulate different screen resolutions:
Most modern browsers (Chrome, Firefox, Edge, Safari) have built-in responsive design mode:
Chrome/Edge: Press F12 (or Ctrl+Shift+I) → Click the Toggle Device Toolbar (📱) icon.
Firefox: F12 → Click the Responsive Design Mode (🖥️📱) button.
Safari: Enable Develop Menu → Enter Responsive Design Mode.
Window Resizer (Chrome Extension)
Quickly switch between preset resolutions.
Web Developer (Firefox/Chrome Extension)
Includes a "Resize Window" tool for testing different dimensions.
Enter a URL (for online tools) or open your local site in the browser.
Select a device/resolution (e.g., iPhone 12, iPad Pro, Desktop 1920×1080).
Check responsiveness – Does the layout adjust correctly? Are images scaling properly?
Test touch interactions (if using a mobile simulator).
✔ Ensure cross-device compatibility
✔ Debug CSS/media query issues
