eDPI calculator
eDPI (effective DPI) is your mouse DPI multiplied by your in-game sensitivity. It lets you compare how fast your aim really is with a friend or a pro player, even if you use different DPI settings. For example, 800 DPI at 0.5 sensitivity and 400 DPI at 1.0 are both 400 eDPI. Only compare eDPI within the same game.

Basics
What is mouse DPI?
DPI stands for dots per inch. For a mouse, it is how many tiny movement steps the sensor reports to your computer for every inch you move it. At 800 DPI, moving the mouse one inch sends 800 steps, so the cursor moves about 800 pixels.
A higher DPI makes the cursor travel further for the same hand movement. A lower DPI means you move your arm more, which many gamers find easier to control. Neither is “better”. It is about what feels comfortable and accurate for you.
You may also see the term CPI (counts per inch). For mice, CPI and DPI mean the same thing. Most gaming mice let you switch between a few DPI levels with a button, which is why it is easy to forget which one you are using. That is what a DPI checker is for.
Step by step
How to check mouse DPI
Option 1: use the DPI tester on this page
- 1
Prepare your settings. Turn off pointer acceleration and set browser zoom to 100% (see below).
- 2
Place a ruler on your desk. Line the front edge or the sensor of your mouse up with the 0 mark.
- 3
Pick the distance. Choose cm or inches and enter how far you will move. 10 cm or 4 inches works well.
- 4
Click the start area. The cursor disappears and the box says “Move now”.
- 5
Move the mouse along the ruler. Go in a straight line at a relaxed pace until you reach your distance, then click.
- 6
Repeat two more times. The DPI analyzer averages your attempts and shows how consistent they are.
Option 2: check it in your mouse software
If your mouse came with an app, it shows the exact DPI levels you have set. This is the most direct way to check mouse DPI, and a good way to confirm the result from the DPI checker above.
- Logitech G HUB
- Select your mouse → Sensitivity (DPI). The active DPI level is highlighted.
- Razer Synapse
- Select your mouse → Performance → Sensitivity stages.
- SteelSeries GG
- Engine → your mouse → CPI settings.
- Corsair iCUE
- Select your mouse → DPI. Each stage shows its value.
- Other brands
- Look for “DPI”, “CPI” or “Sensitivity” in the mouse’s own app or web configurator.
Menu names change between app versions, so the exact path may look slightly different.
No app? Check the box, the manual or the product page. Many mice print their default DPI steps there, and some have a small light that changes color with each DPI level.
Recommendations
What DPI should I use?
There is no single correct DPI. These ranges are common starting points, not rules. Pick one, use it for a few days, and adjust your in-game sensitivity rather than jumping between DPI levels.
| Use | Common DPI | Why |
|---|---|---|
| Tactical FPS (Valorant, CS2)Paired with a low in-game sensitivity for precise aim. | 400 – 1600 | Paired with a low in-game sensitivity for precise aim. |
| Fast FPS / battle royaleA bit more speed for quick turns. | 800 – 1600 | A bit more speed for quick turns. |
| MOBA / RTSMoving the cursor across the whole screen often. | 800 – 2400 | Moving the cursor across the whole screen often. |
| Office and browsingComfortable on 1080p and 1440p screens. | 800 – 1600 | Comfortable on 1080p and 1440p screens. |
| 4K or multi-monitor desktopCovers more pixels without lifting the mouse. | 1600 – 3200 | Covers more pixels without lifting the mouse. |
Many competitive players keep their DPI at 400, 800 or 1600 and tune the in-game sensitivity, because those are standard settings on almost every mouse. Very high DPI values (10,000+) are mostly marketing. They rarely help in games and can make the cursor hard to control.
Troubleshooting
Why is my DPI test result off?
A result within about 5% of a standard value, like 1570 for a 1600 DPI mouse, is normal. Sensors and rulers are not perfect. If you are further off, one of these is usually the reason.
Pointer acceleration is on
Acceleration makes the cursor move further when you move fast, so the result changes with your speed. Turn it off:
- Windows 11: Settings → Bluetooth & devices → Mouse → Additional mouse settings → Pointer Options → untick Enhance pointer precision. Keep pointer speed at the default (10 on the Settings slider).
- macOS: System Settings → Mouse → Advanced → turn off Pointer acceleration (macOS 14 Sonoma and later). On older versions, move at a slow, steady pace.
On Chrome and Edge, this checker asks the browser for raw, unaccelerated movement when it is available. The “Technical details” panel under the tool shows whether it was used.
Display scaling or browser zoom
Windows display scaling (125%, 150%) and browser zoom can make some browsers scale movement values. If your result is off by about the same factor, for example 1280 instead of 1600 at 125% scaling, that is the cause. Reset zoom with Ctrl + 0 (⌘ + 0 on Mac). The checker warns you when it spots this pattern.
Very high polling rate
Polling rate (how often the mouse reports, like 1000 Hz) does not change DPI. At 4000 Hz or 8000 Hz, some browsers and slower PCs struggle to keep up, which can make results jump around. If your attempts vary a lot, try again at 1000 Hz.
The move itself
Lifting the mouse, starting before the 0 mark, or stopping short all change the result. Move over a longer distance, keep the mouse flat on the pad, and stop exactly at the mark. Glossy or glass desks can also confuse some sensors, so use a mouse pad.
FAQ
DPI checker FAQ
How accurate is this DPI checker?
With pointer acceleration off, browser zoom at 100% and a careful 10 cm (4 in) move along a ruler, results are usually within a few percent of your real setting. Doing three attempts and using the average makes it more reliable. Mouse sensors themselves are rarely exact, so a 1600 DPI mouse that measures 1570 is normal.
How do I know my DPI?
There are three ways. If your mouse has its own app, such as Logitech G HUB, Razer Synapse, SteelSeries GG or Corsair iCUE, it shows the exact DPI of each level. Without software, use the DPI checker on this page: move your mouse a measured distance along a ruler and it divides the movement counts by the distance. You can also check the box, manual or product page, which usually list the default DPI steps.
Can I check my mouse DPI without software?
Yes. This page measures DPI in your browser with nothing to install. You only need a ruler or tape measure. If your mouse has its own app, such as Logitech G HUB or Razer Synapse, that app shows the exact setting too.
How do I check my mouse DPI on Windows or Mac?
Use the DPI checker at the top of this page. It works in Chrome, Edge, Firefox and Safari on Windows, macOS, Linux and ChromeOS. Turn off pointer acceleration first (Enhance pointer precision on Windows, Pointer acceleration on macOS) so the mouse DPI test measures your sensor and not the acceleration curve. Neither Windows nor macOS has a setting that shows your DPI, because DPI is stored in the mouse itself.
Why does the DPI test not work on my phone or tablet?
The test counts the movement a real mouse sends to your computer. Touchscreens do not send that kind of movement, so there is nothing to measure. Open the page on a desktop or laptop with a mouse. The eDPI calculator and guides work on any device.
Does Windows pointer speed change my mouse DPI?
No. DPI is a setting inside the mouse. Windows pointer speed only scales how far the cursor moves. It can still change what a browser reports, so keep it at the default (10 on the Windows 11 slider) and turn off Enhance pointer precision while testing.
Is a higher DPI better?
Not by itself. Higher DPI moves the cursor further for the same hand movement. What matters is a speed you can control. Many FPS players use 400 to 1600 DPI with a low in-game sensitivity, while office users often like 800 to 1600 DPI.
Is 800 or 1600 DPI better for gaming?
Neither is better for aim on its own. If you adjust your in-game sensitivity so the eDPI stays the same, 800 DPI and 1600 DPI feel almost identical in game. 800 DPI has long been the most common choice among pro FPS players. 1600 DPI makes the cursor faster on the desktop and on high-resolution screens, and lets you use a lower in-game sensitivity. Pick one, stick with it, and fine-tune the in-game sensitivity instead.
Is 2400 DPI too high?
Not necessarily. Modern sensors track cleanly at 2400 DPI, and it works well for MOBA, RTS, 4K and multi-monitor setups where the cursor has to cover a lot of pixels. For FPS games it is fine if you pair it with a low in-game sensitivity. It is too high only if the cursor feels twitchy and hard to stop on target, or if a game will not let you lower the sensitivity enough. In that case, drop to 800 or 1600 DPI.
Is 800 or 1200 DPI better?
It depends on how fast you want the cursor to move. At 1200 DPI the cursor travels 50% further than at 800 DPI for the same hand movement. 800 DPI is a popular choice for FPS games with a low in-game sensitivity. 1200 DPI is a comfortable middle ground for desktop use on 1440p screens. If you switch, multiply your in-game sensitivity by 2/3 when going from 800 to 1200 DPI (for example, 0.9 becomes 0.6) to keep the same eDPI.
Does this site store or upload my results?
No. The measurement runs entirely in your browser and is gone when you close the tab. Nothing about your mouse movement is sent to us.
