Start Simulating NowFrequently Asked Questions
Why did a new window open?
This tool works by opening a new browser window that is precisely sized to the resolution you selected. This provides the most accurate, interactive simulation possible, as you are viewing the live site in a window that mimics a real device's screen size.
My browser blocked the pop-up. What should I do?
Most browsers have a pop-up blocker to prevent unwanted ads. For this tool to work, you may need to **allow pop-ups** from our website. Look for an icon in your browser's address bar after you click "Simulate" and choose to always allow pop-ups from this site.
Is this the same as my browser's developer tools?
It's similar, but simpler. Browser developer tools (like Chrome DevTools) offer a more advanced device simulation with features like user-agent switching and touch emulation. Our tool provides a quick, easy, and highly accessible way to check resolutions without needing to open developer tools, making it perfect for non-technical users and fast checks.
