Field-of-view converter

Games state FOV three ways. Enter the number your game shows and how it measures it; see the same view in the other two, and on another screen shape.

Screens sold as “21:9” are not exactly 21:9: a 2560x1080 panel is 2.37:1 and a 3440x1440 panel is 2.39:1. Type your resolution (for example 3440x1440) for an exact result.

“4:3-based” is how many Hor+ games label FOV: the number is the horizontal angle a 4:3 screen would show, and wider screens see more at the sides. Formula: horizontal = 2·atan(tan(vertical/2) × width/height). Use these numbers in the zoom match.
