Apex Legends Per Optic Sensitivity Calculator

This calculator works out your effective sensitivity for each weapon optic in Apex Legends, based on your base mouse sensitivity and the game’s per-optic multiplier values. You enter your base sensitivity (in-game sensitivity or DPI/CM per 360) and select an optic, and it returns the adjusted sensitivity for that scope, along with the actual cm/360 distance.

Formula

The effective sensitivity is the base in-game sensitivity multiplied by the optic’s zoom multiplier. The formula is:

Effective Sensitivity = Base Sensitivity × Optic Multiplier

Where:

• Base Sensitivity is your in-game sensitivity setting (a number between 0.1 and 10, typically).
• Optic Multiplier is the game’s built-in sensitivity scaling for that scope (e.g., 1.0 for 1x, 1.45 for 2x and above).
• Mouse DPI is your mouse’s dots per inch setting.

To convert to cm per 360, the formula uses the standard Windows mouse speed multiplier (0.005) and the fact that one inch equals 2.54 cm:

cm per 360 = 360 / (Effective Sensitivity × DPI × 0.005) × 2.54

This gives the physical distance you must move your mouse to turn a full 360 degrees in-game.

Worked Example

Using the default values from the calculator: base sensitivity 2.5, DPI 800, and a 1x optic (multiplier 1.0).

1. Effective sensitivity = 2.5 × 1.0 = 2.5
2. cm per 360 = 360 / (2.5 × 800 × 0.005) × 2.54
3. Denominator = 2.5 × 800 × 0.005 = 10
4. 360 / 10 = 36 inches per 360
5. 36 inches × 2.54 = 91.44 cm per 360

The calculator shows 2.50 effective sensitivity and 91.44 cm per 360, matching the manual calculation.

How Apex Legends Optic Sensitivity Works

Apex Legends applies a uniform sensitivity multiplier to all scopes above 1x. Unlike some games that use a zoom ratio based on field of view, Apex uses a fixed multiplier of 1.45 for every magnified optic (2x, 3x, 4x, 6x, 8x, and variable scopes). This means that switching from a 1x to a 2x scope increases your effective sensitivity by 45%, making the same mouse movement turn 45% more degrees on screen.

This is why many players feel that aiming with a 2x or higher scope is “faster” than with iron sights. The game does not offer a per-optic sensitivity slider in the standard settings (as of the current version), so the only way to adjust it is through external config files or by changing your base sensitivity.

The 1.45 multiplier is consistent across all magnified optics, so the calculator uses that value for every scope above 1x. The 1x optic (including iron sights and the 1x HCOG) has a multiplier of 1.0.

How to Choose Your Sensitivity

Your ideal sensitivity depends on your playstyle, mouse grip, and desk space. Here are some general guidelines:

• Low sensitivity (30-60 cm/360) – common among professional players for precise tracking and flicking. Requires a large mousepad and a light mouse.
• Medium sensitivity (20-30 cm/360) – a balanced middle ground that works for most players.
• High sensitivity (10-20 cm/360) – allows faster turning but makes fine aim harder. Often used by players who rely on wrist movement.

To use the calculator effectively, first find your base sensitivity and DPI. If you already have a cm/360 you like for your 1x scope, you can work backwards: set the optic to 1x and adjust the base sensitivity until the cm/360 matches your preference. Then switch to a magnified optic to see what your effective cm/360 becomes.

Remember that the 1.45 multiplier is fixed – you cannot change it in the game settings. If you want a different multiplier, you would need to use a config file or third-party tool, but that is outside the scope of this calculator.

Common Mistakes and Misconceptions

A frequent error is assuming that the optic multiplier is based on zoom level (e.g., 2x = 2.0, 4x = 4.0). That is not the case in Apex Legends. The multiplier is 1.45 for all magnified scopes, regardless of zoom. So a 4x scope is not four times as sensitive as a 1x – it is only 1.45 times as sensitive.

Another mistake is mixing up DPI and in-game sensitivity. The calculator uses both, but players often forget that changing DPI without changing in-game sensitivity will change the effective sensitivity. For example, doubling DPI while keeping the same in-game sensitivity doubles the effective sensitivity, which halves the cm/360.

Also, the Windows mouse pointer speed setting (usually 6/11) is not included in the formula. The 0.005 factor assumes the default Windows setting. If you have changed the pointer speed, the actual cm/360 will differ, but the relative comparison between optics remains valid.

Why Use a Per-Optic Calculator?

Knowing your per-optic sensitivity helps you understand how your aim will behave when you pick up a weapon with a scope. For instance, if you are used to a certain cm/360 with a 1x, you can predict that a 2x will require 45% less mouse movement to turn the same angle. This can help you adjust your muscle memory or decide whether to change your base sensitivity to compensate.

It is also useful when comparing your sensitivity to other players. Many professional players share their base sensitivity and DPI, but not their per-optic values. With this calculator, you can convert their settings to cm/360 and see how they compare to yours.

Limitations of the Calculator

This calculator uses the standard 1.45 multiplier for all magnified optics, which is correct for the current version of Apex Legends. However, the game may update this value in the future, so always verify with current patch notes.

The cm/360 result assumes a Windows pointer speed of 6/11 and no mouse acceleration. If you use a different pointer speed or have mouse acceleration enabled, the physical distance will be different. Also, the calculator does not account for different mouse sensors or surface friction, which can slightly affect the actual distance.

Finally, the calculator only covers the standard optics. It does not include the “1x-2x” variable scope, which uses a different multiplier (1.0 at 1x and 1.45 at 2x). For that scope, you would need to calculate both states separately.

Frequently Asked Questions

Does the 2x scope use a 2.0 multiplier?
No. In Apex Legends, all magnified scopes (2x and above) use a fixed multiplier of 1.45. This is a deliberate design choice by the developers to keep sensitivity consistent across zoom levels.

Can I change the per-optic sensitivity in the game settings?
As of the current version, Apex Legends does not offer per-optic sensitivity sliders in the standard settings. The only way to change it is by modifying the game’s config files or using third-party software, which may be against the game’s terms of service.

What is the best sensitivity for Apex Legends?
There is no single best sensitivity. It depends on your personal preference, mouse, and playstyle. A good starting point is a cm/360 between 25 and 40 cm, then adjust based on your comfort and accuracy.

Why does my aim feel different with a 2x scope?
Because the effective sensitivity increases by 45% with a 2x scope, your muscle memory for mouse movement will not translate directly. This can make you over-aim or under-aim until you adapt or adjust your base sensitivity.

Does the calculator work for controller players?
No, this calculator is designed for mouse and keyboard players. Controller aim is handled differently, and the game applies its own sensitivity curves for analog sticks.

How do I find my DPI if I don’t know it?
You can check your mouse’s DPI button or software. If you have a gaming mouse, it often has a button to cycle through DPI presets. Alternatively, you can measure the distance it takes to move the cursor across your screen and calculate DPI using an online tool.
