ADS sensitivity converter
Find the ADS multiplier that makes your scope feel like your hipfire aim, from your field of view and a monitor match.
What ADS sensitivity is
When you aim down sights the game narrows your field of view. If the sensitivity stayed the same, the crosshair would race across the screen and a scope would feel twitchy. Games therefore scale the sensitivity down when you scope in, and many let you set the scale yourself: the ADS multiplier, ADS sensitivity or zoom sensitivity.
This tool works out the scale from the maths of the view. You give it your hipfire field of view, the scope’s zoom or field of view, and how you want the two to match. It returns the multiplier, your ADS sensitivity in the game you picked, and the turn distance with the scope on.
How the monitor match works
0% match keeps the centre of the screen matched: a small movement near the crosshair moves the scope the same fraction of the way across the screen as it does in hipfire. 100% match keeps the edge of the screen matched. 56.25% is the vertical edge of a 16:9 screen. Values in between sit between the two.
The formula is multiplier = atan(c × tan(scope FOV ÷ 2)) ÷ atan(c × tan(hip FOV ÷ 2)), where c is the match point from 0 to 1 and the FOVs are horizontal. At 0% it simplifies to the ratio of the tangents, and at 100% to the ratio of the two angles.
Example: with a 90° hipfire FOV, a 4× scope and a 56.25% match the multiplier is 0.273. A hipfire turn of 40 cm per 360° becomes 146.7 cm per 360° through that scope.
Multipliers for a 90° field of view
The multiplier for common scope zooms, with a 90° horizontal hipfire FOV. Use the tool above for your own field of view.
| Scope zoom | Scope FOV | 0% match | 56.25% match | 100% match |
|---|---|---|---|---|
| 1.25× | 77.3° | 0.8 | 0.825 | 0.859 |
| 1.5× | 67.4° | 0.667 | 0.7 | 0.749 |
| 2× | 53.1° | 0.5 | 0.535 | 0.59 |
| 3× | 36.9° | 0.333 | 0.362 | 0.41 |
| 4× | 28.1° | 0.25 | 0.273 | 0.312 |
| 6× | 18.9° | 0.167 | 0.182 | 0.21 |
| 8× | 14.3° | 0.125 | 0.137 | 0.158 |
How to use the result
- Find your field of viewLook in the game’s settings for the hipfire FOV. Enter the horizontal value. If the game gives a vertical value, convert it first; a 16:9 screen is 1.78 times wider than tall in tangent terms.
- Find the scopeEnter the zoom of the scope, or its field of view if the game lists it.
- Pick a matchStart with 0%. Try 56.25% or 100% if scoped flicks feel off.
- Enter it in the gameType the ADS sensitivity or the multiplier where the game asks for it, then test in the practice range with a distant and a close target.
Questions
What is ADS sensitivity?
ADS stands for aim down sights. Scoping in narrows your field of view, so the same mouse movement would swing the crosshair across far more of the screen than before. ADS sensitivity is the setting that slows the turn down so a scope feels like your hipfire aim.
What is monitor distance match?
It is the point on your screen where the hipfire and the scoped view move by the same amount for the same mouse distance. At 0% that point is the crosshair, at 100% it is the edge of the screen. The match point decides how a scoped flick across the screen compares with a hipfire flick.
Which monitor match should I use?
There is no single correct answer. Many players start at 0%, which keeps small movements around the crosshair matched. If scoped flicks to the edge of the screen feel too slow or too fast, move toward 100%. Try one value for a week before you change it.
What is the difference between the ADS multiplier and the ADS sensitivity?
The multiplier says how much the degrees turned per mouse count change when you scope in. A multiplier of 0.5 means the scoped view turns half as far per count. The ADS sensitivity is that multiplier applied to your hipfire sensitivity in the units of the game you picked.
Will this work in every game?
The maths is the same everywhere, but games label and scale their ADS sliders differently. Some use a plain multiplier of hipfire, and others apply their own field of view scaling first. Check how your game describes its ADS setting before you type the result in, and test it in the practice range.
Where do I find the FOV of a scope?
Some games list the scope field of view or the zoom in the settings or the weapon description. If you only know the zoom, enter it and the page works out the scope FOV for you. If you know the scope FOV, enter that and it works out the zoom.
