eDPI Explained for CS2: What It Is and How to Use It

eDPI, or effective dots per inch, is the single number that describes how fast your aim really is in CS2. It combines your mouse DPI and in-game sensitivity. This guide explains how to calculate it, how to turn it into a physical distance and where it falls short.

What is eDPI?

Your mouse reports movement in counts. DPI says how many counts it sends per inch. CS2 then multiplies those counts by your sensitivity. Because both numbers scale your aim, comparing only one of them tells you little.

The formula is simple.

eDPI = mouse DPI x in-game sensitivity

A player on 400 DPI with a sensitivity of 2.0 has an eDPI of 800. A player on 800 DPI with 1.0 also has 800. Their aim moves the same amount for the same hand movement.

eDPI examples and cm/360

cm/360 is how many centimetres you move the mouse to turn a full circle. In CS2, you can get it straight from eDPI. Divide 41,564 by your eDPI. That constant comes from 360 degrees times 2.54 centimetres per inch, divided by the CS2 yaw of 0.022.

A higher number means a faster turn and less mouse travel. A lower number means more travel but finer control.

What eDPI do CS2 pros use?

CSDB tracks the settings of active professionals. Its data from 26 October 2026 covered 820 players. The median was 800 and the average was 856. On DPI, 47% used 400, 46% used 800 and 5% used 1600.

That shows a clear pattern. Professionals mostly play with fairly low values, around 50 cm per turn. It does not mean you must copy them. Pad size, arm or wrist aiming style and comfort all matter. Our sensitivity guide has a simple test for finding your own range.

How do you calculate your eDPI?

1. Check your mouse DPI in its software or on the underside of the mouse.
2. Open CS2 and note your sensitivity in the settings, or type sensitivity in the console to see the current value.
3. Multiply the two numbers.

If you do not know how to enable the console, our console guide walks you through it.

Where the number misleads

• Across games. It only compares setups within the same game. Valorant and CS2 use different yaw values, so an equal number does not mean equal feel. Use our sensitivity converter guide instead.
• Real DPI can differ. Some mice report a DPI that is slightly off. Measuring cm/360 on your pad is the best check.
• Scoped weapons. The figure covers normal aim only. Zoom is set separately with zoom_sensitivity_ratio.

Why do people compare eDPI instead of sensitivity?

Sensitivity alone is meaningless without the DPI behind it. A value of 2.0 sounds fast, but at 400 DPI it is the same as 1.0 at 800. When players share settings, the combined figure is the honest comparison. It tells you straight away whether a setup is faster or slower than yours.

It is also useful when you change hardware. A new mouse may default to a different DPI. Work out your old total, then set your sensitivity so the new total matches. Your aim will feel the same from the first match, and you avoid weeks of relearning.

Should you change your DPI?

You can, as long as you adjust sensitivity to keep the same total. Moving from 400 DPI at 2.0 to 800 DPI at 1.0 changes nothing in game. Some players prefer 800 because desktop use feels smoother. Either choice is fine. What matters is keeping the result steady while you train. Our aim improvement plan explains why that consistency matters, and the aim training guide covers drills.

Sources and checks

Pro figures were checked on 1 November 2026 against CSDB's pro sensitivity data. The CS2 yaw of 0.022 was checked against the CSDB converter.
