Game FOV Converter
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.
How to use Game FOV Converter
- Enter your current field of view value.
- Choose whether that value is horizontal or vertical.
- Enter your aspect ratio, such as 16:9 or 21:9.
- Read the converted FOV on the other axis.
Frequently asked questions
Why does FOV change with aspect ratio?
Games usually lock either horizontal or vertical field of view, so a wider monitor shows more of the other axis, which is why the same setting looks different at 16:9 versus 21:9.
How does it convert horizontal to vertical FOV?
It uses the trigonometric relationship between the two axes and your aspect ratio, so a horizontal FOV maps to the exact vertical angle your screen displays.
What is Hor+ scaling?
Hor+ means a game keeps vertical FOV fixed and adds horizontal view on wider screens; the converter accounts for this so your effective view matches across setups.
