Different games express field of view in different ways: some use horizontal FOV, some vertical, and the number you see depends on your monitor aspect ratio. This converter lets you enter a source FOV, tell it whether that value is horizontal or vertical, set the aspect ratio, and instantly read the matching horizontal and vertical angles. It uses the standard tangent based projection math so the on screen scale genuinely matches, which is what you want when moving between titles or switching from a 16:9 to a 21:9 ultrawide. Getting FOV right affects how much of the world you can see, how large enemies appear, and how comfortable long sessions feel. All calculations happen locally in your browser with nothing sent anywhere, so you can freely test aspect ratios and FOV values until your view feels consistent across your favorite games.
