Display PPI, Pixel Pitch & Aspect Ratio Calculator

Enter the display resolution and either the diagonal size or the active display width and height.

This calculator helps estimate key display specifications including aspect ratio, calculated diagonal, pixel density, pixel pitch, and active display area. It is useful when comparing LCD, OLED, touch panel, industrial display, and embedded display options.

Display Aspect Ratio / Pixel Density Calculator

Calculate display PPI, pixel pitch, aspect ratio, active area, and diagonal size from resolution and physical dimensions.
