The outer rectangle is the scope screen; the inner rectangle is a centred 16:9 image at constant height. Side masking values are geometric clear widths.

Cómo funciona

How to use it: enter clear scope-screen width, exact aspect ratio and eye-to-screen distance.

Formula. Height = width / scope ratio. A same-height 16:9 image has width = height x 16/9.

Example. A 120-inch-wide 2.39:1 screen is about 50.2 inches high and 130.1 inches diagonal.

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

This models image geometry only. Projector memory, zoom range, lens shift, throw, overscan, subtitles, screen border and anamorphic lens compatibility must be checked separately. Film aspect ratios vary.

Preguntas frecuentes

Are 2.35 and 2.39 interchangeable?

They are close but not identical. Use the actual screen ratio to calculate masking and image fit accurately.
