How the DPI Converter Works
When you change your mouse DPI, your in-game sensitivity must change to compensate — otherwise your crosshair will move faster or slower than you’re used to. The formula is:
New Sensitivity = (Current DPI × Current Sensitivity) ÷ New DPI
For example: if you use 800 DPI at sensitivity 1.0 and switch to 400 DPI, your new sensitivity should be 2.0. Your crosshair moves exactly the same distance — muscle memory preserved.
DPI Conversion Examples
| Current DPI | Current Sensitivity | New DPI | New Sensitivity |
|---|---|---|---|
| 800 | 1.0 | 400 | 2.0 |
| 800 | 0.35 (Valorant) | 400 | 0.70 |
| 400 | 2.0 (CS2) | 800 | 1.0 |
| 1600 | 0.5 | 800 | 1.0 |
| 800 | 1.8 (Apex) | 400 | 3.6 |
What is DPI?
DPI (Dots Per Inch) measures how far your cursor moves on screen per inch of physical mouse movement. Higher DPI = faster cursor. Lower DPI = slower, more precise movement.
- 400 DPI — preferred by pro CS2 players for maximum precision
- 800 DPI — most common among competitive FPS players
- 1600 DPI — popular for faster-paced games like Apex Legends
- 3200+ DPI — rarely used competitively
Best DPI Settings by Game
| Game | Recommended DPI | Pro Avg Sensitivity | Pro Avg eDPI |
|---|---|---|---|
| CS2 | 400–800 | 1.0–2.5 | 800 |
| Valorant | 800 | 0.27–0.45 | 280 |
| Apex Legends | 800 | 1.5–2.5 | 1400 |
| Fortnite | 800 | 0.065–0.085 | 60 |
| Warzone | 800 | 1.5–2.5 | 1600 |
| Overwatch 2 | 800 | 3.0–5.0 | 3200 |
Does Changing DPI Affect Aim?
Yes — if you change DPI without adjusting sensitivity, your aim will feel completely different. Always recalculate your sensitivity when switching DPI. Most pros stick to 400 or 800 DPI because these are native sensor values on most gaming mice, ensuring clean tracking without interpolation.
Frequently Asked Questions
How do I change DPI without losing my sensitivity?
Use the formula: New Sensitivity = (Current DPI × Current Sensitivity) ÷ New DPI. Example: 800 DPI at 1.0 sensitivity → switch to 400 DPI → new sensitivity = 2.0. Your eDPI stays at 800.
What sensitivity should I use at 400 DPI vs 800 DPI in CS2?
If you use 800 DPI at 1.0 sensitivity, switch to 400 DPI at 2.0 sensitivity. Both give eDPI of 800. Most CS2 pros use 400 DPI with sensitivity 1.5–3.0, giving eDPI of 600–1200.
What is the best DPI for FPS gaming?
Most competitive players use 400 or 800 DPI. These are native sensor values on most gaming mice (Logitech G Pro, Razer DeathAdder, SteelSeries Rival), meaning clean tracking with no hardware smoothing.
Does higher DPI mean better aim?
No. Higher DPI just means faster cursor movement. What matters is your eDPI (DPI × sensitivity). 400 DPI at 2.0 sensitivity = 800 DPI at 1.0 sensitivity. Both have eDPI of 800 — identical true sensitivity.
Can I use this for any game?
Yes. Works for CS2, Valorant, Apex, Fortnite, Warzone, Overwatch 2 and more. To convert sensitivity between different games, you need a sensitivity converter that accounts for each game’s yaw value.
