Cómo funciona

How to use it: enter screen size, viewing distance and an editable pixels-per-degree comparison target. The tool shows angular pixel density for 1080p, 4K and 8K and the distance where each reaches that target.

Formula. PPD = horizontal pixel count / horizontal viewing angle. Target distance is found by solving for the angle equal to pixels / target PPD.

Example. At the same size and seat, 8K has twice the horizontal PPD of 4K and four times that of 1080p.

Antes de usar el resultado

  • Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
  • Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
  • When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Limitaciones

PPD describes geometry, not whether a person can perceive a difference. Vision, contrast, compression, mastering, motion, scaling and content detail all matter. Do not interpret the target as a clinical eyesight threshold.

Preguntas frecuentes

Does farther always mean better?

Farther increases angular pixel density but reduces immersion. Use this together with viewing angle rather than optimizing one number alone.
