Best FOV Settings for Gaming: Why Minecraft’s 70 and Valorant’s 103 Are the Same View

Minecraft’s default FOV of 70 and Valorant’s fixed 103 show almost exactly the same picture on a 16:9 monitor. The sliders count different things: Minecraft measures the vertical angle, Valorant the horizontal one, and 70° vertical works out to 102.4° horizontal at 16:9. That hidden axis is why “best FOV” advice copied from one game to another so often goes wrong.

A FOV number only means something once you know the axis, your aspect ratio and how far you sit from the screen. This guide covers the conversion maths, what FOV really changes on screen (target size, not just “seeing more”), the monitor-distance geometry most guides skip, and starting values by game type. It is part of our complete guide to optimizing PC game settings; this page goes deep on one setting, and the hub covers the rest.

Quick Start: Set Your FOV in Five Steps

1. Find your game’s axis. Check the table below. If the game doesn’t say whether its slider is horizontal or vertical, assume nothing and compare it to a known value.
2. Start at 90-100° horizontal (about 59-68° vertical at 16:9) for a first-person game on a PC monitor. As a general guideline, that range balances awareness against target size.
3. Change in 5° steps and test each in the same familiar spot for a few minutes.
4. Judge by symptoms. If the world feels zoomed-in or you feel queasy, go up 5°. If targets feel tiny or the edges look stretched, go down 5°.
5. Re-check mouse sensitivity afterwards, because FOV changes how far each turn travels across the screen.

Horizontal vs. Vertical FOV: The Hidden Setting Behind the Number

Every FOV number is an angle measured along one axis, and games disagree on which. Unity’s own documentation is explicit: “This is the vertical field of view; horizontal field of view depends on the viewport’s aspect ratio” (Unity Scripting API). To convert, use plain trigonometry: horizontal FOV = 2 × atan(tan(vertical FOV ÷ 2) × aspect ratio), where 16:9 is 1.778.

The numbers in the Minecraft row come from the Minecraft Wiki’s Options page, and they match the formula. The takeaway: a Minecraft player at the default 70 sees the same width of world as a Valorant player at 103, so “use 103 like the pros” is meaningless until you know which axis your slider uses.

Why the same slider changes on an ultrawide

Most modern games use “Hor+” scaling: the vertical angle stays fixed and the horizontal angle grows with a wider aspect ratio. “Vert-” does the opposite, keeping the horizontal angle and cropping the top and bottom (Wikipedia). On a Hor+ game, a view that is 103° wide on 16:9 becomes about 117.6° on 21:9 and 136.6° on 32:9 at the same slider value. If your view suddenly feels stretched after an ultrawide upgrade, lower the slider before blaming the monitor. Our ultrawide vs. standard monitor comparison covers the rest of that decision.

What FOV Actually Changes on Screen

Raising FOV does more than add view at the edges: it shrinks everything at the centre, because the same screen width now stands for a wider slice of the world. In a standard perspective projection, an object’s size at the crosshair scales with 1 ÷ tan(FOV ÷ 2). Here is that maths for a 2560×1440 screen, with 90° as the reference.

In plain terms: going from 60° to 100° makes a distant enemy about half the size (2.06× smaller), and going from 90° to 110° shrinks them by roughly 30%. Those figures are my own calculation from the projection formula rather than a measured benchmark, and they hold at the screen centre; objects near the edges are stretched further.

Three side effects follow from the same geometry:

• Peripheral awareness. A wider angle shows flankers you would otherwise miss, which is the entire competitive case for high FOV.
• Edge stretch. Very wide values bend the picture near the edges; TheGamer’s Apex Legends FOV guide describes the 105-110 range as adding fisheye-style distortion.
• Render cost. Engines skip objects outside the camera frustum, the volume whose sides are the FOV boundaries, according to Unity’s glossary entry on frustum culling. A wider FOV pulls more objects inside it.

I could not find a controlled FOV-versus-frame-rate benchmark from a major hardware outlet, and community figures vary too widely to quote. Treat the cost as real but game-dependent (probably largest in dense scenes and on CPU-limited systems), and measure it yourself with your game’s FPS counter.

Your Monitor Distance Sets the “True” FOV (and Why Shooters Ignore It)

The geometrically correct horizontal FOV for a typical desk setup is roughly 43-55°, about half of what shooters default to. It comes from the same relationship Unity’s manual gives for camera angle: FOV = 2 × atan(screen width ÷ (2 × viewing distance)).

Set the game to that number and the screen behaves like a window: objects appear true to life size. Set 100° on a 27-inch monitor at 24 inches and the same maths says the world is shown at about 0.41× life size. That is a deliberate competitive trade, not a bug: you give up realism of distance and speed to buy awareness.

Where realism matters more than awareness, such as cockpit racing or flight sims, the monitor-matched value is the more defensible starting point. In first-person shooters it usually isn’t. If you are choosing a screen size, our monitor size guide shows how width and distance interact.

Best FOV by Game Type

Work down this decision tree and stop at the first branch that applies:

1. Does the game lock FOV? Valorant has no slider and CS2 locks it in matchmaking, so stop. CS2’s viewmodel_fov (54-68, default 60) only resizes the weapon model and, per CSDB, changes nothing about how much of the map you see.
2. Is it competitive first-person? Use the widest value at which you can still track targets.
3. Is it single-player first-person? Start at 90-100°.
4. Is it third-person? Start lower, around 75-85°, because the camera already supplies spatial context.
5. Is it a cockpit or sim? Start from the monitor-matched value in the table above.

The 75-85° and 90-100° bands are practitioner guidelines rather than official figures, so use them as a first test position.

Comfort and Performance: What the Evidence Does and Doesn’t Say

Advice on motion sickness points in opposite directions, and both are partly right. Wikipedia notes that narrow console-style FOV values on a close PC monitor can cause disorientation, dizziness or nausea. In a 2023 experiment, Yip and Saunders found that restricting attention to the central visual field reduced motion sickness (average scores of 0.85 versus 2.175 for peripheral attention, 40 participants), and they note this fits earlier findings that smaller-FOV displays reduce discomfort. That study manipulated attention rather than FOV itself, so it is indirect evidence.

The practical reconciliation is a mismatch: both a view far narrower than the screen can justify and a stretched, very wide one can feel wrong. Start at 90-100° and move in 5° steps, as in the Quick Start. Our motion sickness settings guide covers the other settings that interact with FOV.

Set Sensitivity and Frame Rate After FOV

Sensitivity is normally defined as degrees of turn per mouse count, so a different FOV doesn’t change how far you turn, only how many pixels that turn drags across the screen (see the table above). After any change of 10° or more, expect to nudge sensitivity; our DPI, polling rate and sensitivity guide shows how to do it without guessing. If a wider FOV pushes your frame rate below your refresh rate, variable refresh rate smooths the dips; see G-Sync vs. FreeSync vs. VRR explained.

FOV FAQ

Is 103 FOV in Valorant the same as 103 in Overwatch 2?

Yes at 16:9, because both are horizontal values and both work out to roughly 70.5-71° vertical. Where players go wrong is comparing either one to Minecraft’s 70 or a vertical slider, which describes a very different number for the same view.

Is higher FOV always better for competitive play?

No. Every step up shows more of the sides and shrinks the centre (0.70× at 110° versus 90°), so you trade spotting flankers against hitting distant targets. Overwatch pros clustering at the 103 cap shows they value awareness, but it can’t show they would go higher, since the game stops there.

Does a higher FOV lower my FPS?

Usually, because more objects fall inside the frustum, but the size of the hit is game-specific and I found no reliable benchmark to quote. If you are near a frame-rate target, change FOV by 10° and read the counter before deciding.

Should I set FOV to match my monitor distance?

Only for sims and racing, where true-scale distance and speed matter. In shooters the matched value (roughly 43-55°) would hide your flanks, so the trade-off favours something wider.

Values verified October 4, 2026. Slider ranges and locks (Overwatch 80-103, CS2 and Valorant fixed) can change with patches, so confirm in your game’s settings menu.
