Screen Aspect Ratio & Dimension Calculator


Calculate image dimension (in pixels) from total number of pixels and aspect ratio

Aspect Ratio: [1.00 = square] [1.25 = 5:4] [1.33 = 4:3] [1.50 = 3:2] [1.60 = 16:10] [1.67 = 5:3] [1.71 = 128:75] [1.78 = 16:9] [1.85] [2.33 = 21:9 (1792x768)] [2.35 = Cinamascope] [2.37 = "21:9" (2560x1080)] [2.39 = Panavision]

Calculate optimal viewing distance from screen size

For a screen that is ( in | cm ) diagonal and ( 4:3 | 16:9 ), the optimal viewing distance is between and , ideally around (based on screen height (4H-8H,6H))
alternately: between and , ideally around (based on screen width (2W-5W,3W))

Calculate screen dimensions (height/width/area, in inches or cm) from diagonal measurement and aspect ratio
