eDPI Calculator - Mouse DPI and In-Game Sensitivity

An eDPI calculator combines your mouse hardware DPI with the in-game sensitivity value into a single comparable number, called effective DPI or eDPI, so you can compare mouse setups across CS:GO, Valorant, Fortnite, Call of Duty, Overwatch 2, and Apex Legends.

• • Compare your setup with a friend's: Plug in your mouse DPI and sensitivity, then read the eDPI value and see if it matches.
• • Match pro player settings on a new mouse: Read a pro's eDPI and the calculator shows the in-game sensitivity.
• • Switch between CS:GO, Valorant, and Fortnite: Pick a different game and the calculator re-scales the same eDPI, including Fortnite's percent conversion.
• • Diagnose a sensitivity that feels off: Compare the eDPI to the pro range to step toward the pros.

Before chasing a pro player's eDPI, the is it worth it calculator turns the cost versus benefit of a new mouse into a quick yes or no number so the decision is on the page before you spend the money.

The calculator applies the effective DPI formula to your mouse DPI and in-game sensitivity, then looks up the typical pro-player range for the selected shooter so you can see how your settings compare.

• Game: The shooter you are configuring. CS:GO, Valorant, COD, Overwatch 2, and Apex Legends use a decimal sensitivity; Fortnite uses a percent.
• Mouse DPI: Hardware dots per inch from your mouse driver or spec sheet. 800 DPI is the most common gaming setting, with 400 and 1600 close behind.
• In-game sensitivity: The number the game multiplies your mouse movement by. For CS:GO a typical value is 1.0 to 2.0; for Valorant it is 0.3 to 0.5; for Fortnite it is 5% to 12%.
• Target mouse DPI: The DPI of the mouse you are moving to, used by the conversion helper to find the in-game sensitivity that keeps the same eDPI.

When you switch the game selector from CS:GO to Fortnite, the same numeric value gets re-interpreted. A 1.0 in CS:GO is a multiplier of 1, but a 1.0 in Fortnite is 1%, a 0.01 multiplier. The calculator divides the percent by 100 in the background so the eDPI value stays consistent.

According to ProSettings' CS2 pro settings page, professional CS:GO and CS2 players cluster between 700 and 1500 eDPI, with the typical pro value sitting near 900 eDPI on an 800 DPI mouse.

According to Wikipedia's Computer mouse article, dots per inch (DPI) is the standard unit for mouse sensor resolution and counts how many positional changes the sensor reports per inch of physical movement, which is the input the eDPI formula multiplies by the in-game sensitivity.

For another one-screen tool that follows the same few inputs in, one useful number out pattern, the time lapse calculator takes a small set of interval and duration settings and returns the finished clip length in the same single-form layout.

Four ideas explain almost every question about eDPI. Read these once and the rest of the page makes sense.

Once you understand polling rate, the data transfer calculator plugs in file size and link speed to return the actual transfer time, the same bytes per second math that drives a 1000 Hz mouse sensor.

Four inputs cover the common cases: switching games, comparing setups, and matching a known eDPI on a new mouse.

1. 1 Pick the game: Choose the shooter you are configuring. Use CS:GO / CS2, Valorant, Call of Duty, Overwatch 2, or Apex Legends for decimal games, or Fortnite for percent sensitivity.
2. 2 Enter your mouse DPI: Type the hardware DPI from your mouse software. Most gaming mice are 400, 800, or 1600 DPI; high-end wireless mice go up to 26,000 DPI.
3. 3 Enter your in-game sensitivity: Type the number you set inside the game. CS:GO, Valorant, and Apex accept values like 0.4, 1.0, or 1.6. Fortnite accepts a percent like 5, 8, or 12.
4. 4 Set a target mouse DPI: If you plan to move to a new mouse, set the target mouse DPI to the value the new mouse supports. The conversion helper returns the in-game sensitivity to use so the eDPI stays the same.
5. 5 Read the eDPI, the pro range, and the matched sensitivity: The eDPI is your effective DPI. The pro range shows the typical pro window, and the matched sensitivity is the in-game value to enter on the target mouse DPI.

A 800 DPI CS:GO player running 1.0 sensitivity has eDPI 800, inside the 700-1500 CS:GO pro range. After upgrading to a 1600 DPI mouse, they enter 1600 in the target DPI field and read 0.5 as the matched sensitivity, so the feel is unchanged.

If you are moving from a wired tournament mouse to a wireless one and want to know how long the new mouse will run on a charge, the battery capacity calculator converts amp-hours, watt-hours, and C-rate the same way this calculator converts mouse DPI and in-game sensitivity into one comparable number.

One form covers the three reasons players reach for an eDPI calculator: comparing setups, switching mice, and finding the pro range for their game.

• • Compare setups in one number: Read a single eDPI value instead of mentally multiplying DPI by sensitivity.
• • Match a known eDPI on any mouse: Set the target mouse DPI to reproduce the same eDPI on the new mouse.
• • Cover CS:GO, Valorant, Fortnite, and four other shooters: The game selector handles CS:GO, Valorant, Call of Duty, Overwatch 2, Apex Legends, and Fortnite.
• • See the typical pro eDPI range for the selected game: The pro range shows the low and high eDPI values that professional players use, plus a typical midpoint.
• • Switch mice without losing aim: The matched-sensitivity helper takes the guesswork out of moving from a 400 DPI tournament mouse to a 1600 DPI wireless one.
• • Diagnose sensitivity that feels off: Compare your eDPI to the pro range and the calculator highlights whether you are below, inside, or above the typical pro window.

After dialing in the perfect eDPI, the hobby cost calculator tracks how much you have spent on mice, pads, and other gear, so the total cost of chasing the pro range sits next to the eDPI you ended up with.

The eDPI calculator is a pure formula, but four real-world factors change the feel of the same eDPI in different games and on different mice.

• • The pro range readout is a guideline, not a target. The pro range comes from ProSettings aggregates and changes as the pro scene evolves.
• • In-game acceleration overrides eDPI math. Turn off mouse acceleration in the game settings before trusting the eDPI value.
• • Sensor scaling can shift the apparent eDPI. Two mice with identical 800 DPI can feel slightly different because sensors are not perfectly linear.
• • The calculator does not model Windows settings. Set pointer speed to 6/11 and disable Enhance Pointer Precision.

According to ProSettings' Valorant pro settings page, professional Valorant players cluster between 200 and 360 eDPI, well below the CS:GO range because Valorant uses a wider 103 degree horizontal field of view and separate horizontal and vertical sensitivity multipliers.
