Calculate pixel density (PPI), dot pitch (mm), total megapixels, and physical screen dimensions.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose 4K 27", 1080p 24", or enter custom width/height pixels and diagonal inches.
View PPI pixel density, dot pitch (mm), total megapixels, and aspect ratio.
Copy the display specifications with one click.
PPI = sqrt(Width_px^2 + Height_px^2) / Diagonal_inches.
Dot pitch is the physical distance between adjacent pixels on a display panel, calculated as 25.4 mm / PPI.
