Screen Aspect Ratio & Dimension Calculator

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

Aspect Ratio: Pixels:
1.00 = square
1.25 = 5:4
1.33 = 4:3
1.50 = 3:2
1.60 = 16:10
1.67 = 5:3 (15:9)
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
Choose Aspect Ratio

An image with 2073600 pixels and an aspect ratio of 1.778 would have dimensions of: 1920x1080

Calculate the missing value from two of height, width and/or aspect ratio

Aspect Ratio: Width: Height:
1.00 = square
1.25 = 5:4
1.33 = 4:3
1.50 = 3:2
1.60 = 16:10
1.67 = 5:3 (15:9)
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
Choose Aspect Ratio

Aspect ratio: 1.778
Width: 1920
Height: 1080

Calculate optimal viewing distance from screen size

For a screen that is ( in | cm ) diagonal and ( 4:3 | 16:9 | 21:9 ), the optimal viewing distance is between 8 feet and 16 feet, ideally around 12 feet (based on screen height (4H-8H,6H))
alternately: between 7 feet and 18 feet, ideally around 11 feet (based on screen width (2W-5W,3W))

Calculate screen-size to body-size ratio

My device is wide and high, with a diagonal screen size of and resolution/aspect ratio of x .
The screen (5.23x2.94) takes up 76.91% of the device surface area.

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