Our Mission
We built screenresolutionsize.com because every existing screen resolution checker tool had at least one major frustrating problem — a "Check Now" button you had to click before seeing results, a cluttered UI drowning in ads, screen resolution and viewport size mixed up, no real-time updates on resize, or simply showing wrong numbers on high-DPI displays. We fixed every one of those issues. Our tool shows 12 precise display metrics the instant you land on the page — zero clicks, zero signup, zero ads.
Instant Detection
Your resolution appears the moment the page loads. No button click needed — unlike 90% of other tools.
12 Metrics, Not Just One
Screen resolution, viewport, DPR, aspect ratio, color depth, refresh rate, PPI, orientation, HDR, touch support — all in one place.
Truly Live Updates
Resize your browser and watch every metric update in real time. Designed for developers who actually resize windows.
Zero Tracking
Everything runs purely in your browser via JavaScript APIs. Nothing is sent to any server. No cookies, no tracking.
Works on All Devices
Fully tested on iPhone, Android, iPad, Mac, Windows, Linux — from 320px mobile to 8K television screens.
Built for QA Teams
One-click "Copy Specs" exports your full display report ready to paste into Jira, GitHub, or Slack.
Who We Are
We are a small team of web developers and UX engineers who were frustrated by the poor quality of free online screen resolution tools. We spent weeks analysing competitor products, identifying exactly what they got wrong, and building a better version from the ground up. screenresolutionsize.com launched in 2025 and is completely free to use — forever. For any questions or feedback, reach us at viratsaxena79@gmail.com.
Why Screen Resolution Matters
Screen resolution affects web design, gaming performance, photo editing, video production, responsive development, and everyday digital experience. Knowing your exact resolution, viewport size, and DPI lets developers write better media queries, lets designers optimise assets for each device, lets gamers choose the right settings, and lets QA engineers file better bug reports. Our mission is to make this information instantly accessible to everyone for free.
Our Commitment to Accuracy
We use the most reliable browser APIs available: screen.width, window.innerWidth, window.devicePixelRatio, and requestAnimationFrame for refresh rate measurement. We test against known device specs from Apple, Samsung, Google, and Microsoft to validate every reading. If you find any inaccuracy, please contact us immediately at viratsaxena79@gmail.com — we take data quality seriously.
