RealDPI — Mouse Sensitivity Converter & Real DPI Calculator

How to Use

Select your current mouse from the left dropdown.
Enter the DPI setting you currently use.
Select your new mouse from the right dropdown.
Click Calculate Equivalent DPI.
Set your new mouse to the result — your sensitivity will feel identical.

What is Real DPI?

The DPI value shown on a mouse is the advertised value — but the actual tracking speed often differs. Every sensor is calibrated differently by the manufacturer, so a 800 DPI setting on one mouse may track faster or slower than 800 DPI on another.

Real DPI is the measured tracking speed of a mouse at a given setting. RealDPI uses these real measurements to calculate a conversion that feels accurate — not just mathematically equivalent.

FAQ

Why does my sensitivity feel different even at the same DPI?

Because the advertised DPI and the actual measured DPI of a mouse are not always the same. Sensor tuning varies by manufacturer and model, causing real differences in tracking speed.

How accurate is the conversion?

The conversion is based on real measured DPI data from our own testing and insights from verified professional and former professional players. We make every effort to ensure the highest level of accuracy, though minor differences in feel can still occur due to hardware variation between individual units.

My mouse isn't in the list. What should I do?

We are continuously adding new mice as data becomes available. If your mouse is not listed, feel free to contact us at jasingod@gmail.com and we'll look into adding it.

What is eDPI and how is it different from DPI?

eDPI (effective DPI) is your mouse DPI multiplied by your in-game sensitivity. For example, 800 DPI with in-game sensitivity 2.0 equals 1600 eDPI. eDPI is the number that actually determines how fast your crosshair moves, making it a more reliable comparison metric. Most professional FPS players use between 200 and 800 eDPI.

Does polling rate affect DPI accuracy?

Polling rate (Hz) controls how often the mouse reports its position — it does not affect the DPI value itself. However, low polling rates (125 Hz) can cause positional data loss between reports, making movement feel imprecise. For competitive play, 500–1000 Hz is standard. High-end mice now offer 4000–8000 Hz modes for even lower input latency.

Should I use a high or low DPI setting?

It depends on your play style. Lower DPI (400–800) with higher in-game sensitivity gives more precise control and reduces the effect of small hand tremors. Higher DPI (1600+) feels more responsive but requires steadier hands. What matters most is picking a setting and sticking with it — consistency builds muscle memory.

Is RealDPI free to use?

Yes, RealDPI is completely free. No account or registration required.

About RealDPI

RealDPI is a free mouse sensitivity converter built on empirically measured DPI data — not manufacturer spec sheets. When you switch gaming mice, setting both to the same DPI rarely feels the same, because every mouse sensor tracks at a slightly different real speed than its advertised value. RealDPI measures that actual tracking speed for each mouse model and uses it to find the exact DPI setting on your new mouse that preserves your muscle memory.

The database currently covers 180+ gaming mice from brands including Logitech, Razer, Zowie, SteelSeries, Pulsar, ASUS ROG, and many more. DPI measurements are collected using the Lego Method — a standardized community testing technique that records cursor displacement over a precisely measured physical distance at each DPI step. The result is a ground-truth figure that reflects how the mouse actually behaves, not how the manufacturer labeled it.

Alongside the converter, RealDPI offers a Shape Finder tool that uses your device camera and hand-tracking to match your grip dimensions to the best-fitting mouse shape, a Pro Setups database with DPI and sensitivity data for top competitive players across CS2, VALORANT, Apex Legends, and Fortnite, and a full mice list covering 900+ models. All tools are completely free — no account or registration required.
