Display & Screen Calculators

PPI Calculator

Compute pixels per inch from screen resolution and physical diagonal. Includes Retina estimate and dot pitch.

Pixel Density Calculator

Calculate pixel density, total display megapixels, aspect ratio, and visual sharpness categories.

Screen Size Calculator

Calculate exact physical width, height, surface area, and diagonal dimensions for any screen aspect ratio.

Aspect Ratio Calculator

Simplify resolution ratios (16:9, 16:10, 21:9, 32:9), find decimal proportions, and resize dimensions.

Dot Pitch Calculator

Convert between PPI and physical dot pitch in millimeters and microns (μm). Check subpixel sizing.

Viewing Distance Calculator

Calculate minimum viewing distance based on 20/20 human eye resolution (1 arcminute) and THX guidelines.

4K PPI Calculator

Explore pixel density, dot pitch, and optimal viewing distances across all 4K UHD screen sizes (24″ to 85″).

8K PPI Calculator

Analyze pixel density and resolving limits for 8K UHD displays (33.2 Million Pixels) from 32″ to 98″.
