Designing for today's multi-device world means ensuring your site looks sharp on every screen—from 4K monitors to tiny phone displays. Our Webpage Screen Resolution Simulator lets you emulate popular resolutions and devices in real-time, helping you spot layout breaks, scaling issues, or font glitches without switching hardware or apps.
Just paste any URL, select from 50+ presets (like iPhone 14, iPad Pro, 1920x1080 desktop, or custom pixels), and click "Simulate." The tool renders a live iframe preview with zoom controls, pixel-perfect measurements, and side-by-side comparisons. It mimics viewport behavior, including touch gestures on mobile emulations, so you can test navigation and interactions too.
Why developers and designers make it their go-to:
Whether you're building e-commerce pages, landing sites, or apps, this simulator streamlines responsive workflows and cuts debugging time. No plugins, no setup—load and test instantly, completely free, with unlimited sessions!
