dpi sensitivity calculator

What this DPI sensitivity calculator does

A DPI sensitivity calculator helps you convert in-game sensitivity when you change mouse DPI, so your aim feels consistent. Many players upgrade mice, test new polling rates, or copy pro settings and accidentally change their effective speed. This page fixes that by calculating a mathematically equivalent sensitivity.

The core idea is simple: keep your eDPI (effective DPI) the same. If eDPI remains constant, your base turn speed stays the same in most games that use raw input.

DPI vs Sensitivity vs eDPI

DPI (dots per inch)

DPI is your mouse hardware sensitivity. Higher DPI means more cursor counts per inch of movement.

In-game sensitivity

In-game sensitivity is a software multiplier applied by the game engine. It scales how much camera rotation each mouse count produces.

eDPI (effective DPI)

eDPI combines both values:

If you double DPI and cut sensitivity in half, eDPI stays the same, and your base aim speed remains nearly identical.

Formulas used by this calculator

To keep the same feel after changing DPI:

Optional cm/360 estimate (if yaw is known):

How to use it

• Enter your current DPI.
• Enter your current in-game sensitivity.
• Enter your target DPI.
• Leave yaw at default unless you know your game's exact value.
• Click Calculate and copy the new sensitivity into your game settings.

Example conversion

Suppose you currently use 800 DPI and 1.20 sensitivity, but you want to switch to 1600 DPI.

Your current eDPI is:

New sensitivity should be:

So, use 0.60 sensitivity at 1600 DPI to preserve your aim speed.

Why players also track cm/360

eDPI is useful, but cm/360 gives a physical measurement: how many centimeters you move your mouse for one full in-game turn. This helps you compare settings across games more reliably, especially if each game handles multipliers differently.

• Lower cm/360: faster turning, less arm travel.
• Higher cm/360: slower turning, more precision potential.

Common mistakes to avoid

• Changing DPI without adjusting in-game sensitivity.
• Comparing sensitivity values directly across different games.
• Ignoring game-specific settings like ADS multipliers or scoped sensitivity.
• Switching too often and never allowing time to adapt.

Practical setup tips

1) Keep one baseline

Pick a baseline sensitivity and only make small adjustments (2% to 5%) after real play sessions.

2) Disable acceleration for consistency

Mouse acceleration can make movement non-linear, which complicates true sensitivity matching.

3) Test with repeatable drills

Use the same aim training routine for each settings change so your comparison is fair.

4) Confirm polling rate and raw input

These settings can affect feel and tracking smoothness even when eDPI is identical.

FAQ

Is higher DPI always better?

No. Higher DPI can reduce quantization in some cases, but comfort and consistency matter more than extreme numbers.

Can I use this for any FPS game?

Yes for baseline conversion. For exact cross-game matching, include each game's own sensitivity scale and yaw behavior.

Why does the same eDPI feel slightly different between games?

Different engines, FOV models, ADS scaling, and input pipelines can all change perception even at matched eDPI.

Bottom line

If you change mouse DPI, use this calculator to keep your sensitivity equivalent and avoid retraining from scratch. Start with mathematically matched settings, then fine-tune in small steps based on actual performance.
