Classify your device hardware tier with our free Device Type tool. Detect Mobile, Tablet, or Desktop categories, touchscreen capability, max touchpoints, screen orientation, and Device Pixel Ratio (DPR) directly inside your browser with complete privacy.
Open the tool to trigger automatic viewport and touch property inspection.
View the highlighted device frame pill (Mobile, Tablet, or Desktop).
Check touch points, screen orientation, and Device Pixel Ratio scaling metrics.
Evaluates window.innerWidth and touch API indicators for accurate hardware classification.
Continuously re-evaluates viewport breakpoints when browser windows are resized or rotated.
All diagnostics execute in local browser memory. Zero device specs leave your computer.
Device class detection combines CSS Media Query breakpoints (window.innerWidth) with DOM API capabilities. Viewports \(\le 480\text{px}\) classify as Mobile, \(\le 1024\text{px}\) as Tablet, and larger as Desktop.
Touchscreen input capability is verified through 'ontouchstart' in window and navigator.maxTouchPoints, distinguishing touch-first mobile devices from mouse-driven desktop displays.
Device Pixel Ratio (window.devicePixelRatio) indicates subpixel rendering resolution (e.g. Retina displays at 2.0x or 3.0x), enabling web layouts to serve crisp high-density assets.
