What Is a "Canonical Pixel" and Why Does It Matter?
Every FPS game uses its own internal unit for crosshair size. CS2 measures in integer steps, Valorant uses a decimal scale, Apex Legends has its own multiplier, and Overwatch 2 uses yet another unit entirely. This makes it impossible to directly compare settings between titles — a value of 2 in CS2 does not feel the same as a 2 in Valorant.
Our converter solves this by translating every game's unit into a canonical pixel half-arm length: the physical number of pixels that make up one arm of your crosshair when rendered at 1920×1080. This measurement is absolute and game-agnostic. A canonical value of 4 px looks identical in every game — it always occupies exactly 4 pixels from the crosshair centre to the tip of one arm at 1080p.
| Game | Pixels Per Unit | Example: Size 5 | Size Range |
|---|---|---|---|
| CS2 | 2.0 px/unit | 10.0 canonical px | 0 – 10 |
| Valorant | 1.0 px/unit | 5.0 canonical px | 0 – 10 |
| Apex Legends | 6.0 px/unit | 30.0 canonical px | 0.5 – 5 |
| Overwatch 2 | 1.8 px/unit | 9.0 canonical px | 0 – 100 |
| Warzone | 5.0 px/unit | 25.0 canonical px | 1 – 10 |
| Fortnite | 5.0 px/unit | 25.0 canonical px | 1 – 10 |
| Rainbow Six Siege | 2.5 px/unit | 12.5 canonical px | 1 – 10 |
Pixel-per-unit coefficients are measured via pixel-ruler screenshots at 1920×1080 with default zoom. Values are accurate to within ±5% across driver and OS configurations.
Does Crosshair Size Actually Affect Your Aim?
Yes — significantly. Crosshair size is a mechanical variable, not just a cosmetic preference. The size of your crosshair determines how precisely you can identify the exact pixel your aim rests on. Larger crosshairs obscure your target; smaller ones demand higher precision to align correctly.
Tiny (0–3 px)
Preferred by elite players. The centre gap and minimal arm length maximise target visibility. Requires precise mouse control — the crosshair cannot mask an enemy hitbox.
Small–Medium (3–10 px)
The "sweet spot" for most intermediate players. Easy to locate on-screen during fast movements while retaining enough target visibility for precise shots.
Large–Huge (10+ px)
Common in console defaults and beginner settings. Easy to track but large arms obscure long-range targets. Most competitive players reduce size as their skill increases.
Research on visual attention in gaming environments, cited by Esports Healthcare, suggests that smaller, high-contrast crosshairs reduce visual noise and allow the eye to focus more effectively on target movement — a measurable advantage at the highest levels of play.
Pro Player Crosshair Settings Explained
The consensus among top-ranked professionals is clear: smaller is almost always better. An analysis of the top 50 CS2 pro players on ProSettings.net shows that over 80% use crosshair sizes between 1 and 3 — which translates to just 2–6 canonical pixels. This concentration in the Tiny to Small tier is not coincidental.
Notable Pro Settings (Canonical Pixels)
Bar scale: 50px = 100%. s1mple and m0NESY are the most extreme examples of minimal crosshair philosophy in competitive play.
The key insight is that pros optimise for one thing: seeing the target clearly. Device uses a slightly larger size because his AWP-heavy playstyle requires fast target acquisition over multiple angles — the slightly larger crosshair helps him land on-target after a fast flick. Riflers like s1mple minimise size to maximise the hitbox visible behind the crosshair.
The Conversion Formula
Our converter uses a two-step process. First it converts your source game's size into canonical pixels. Then it divides by the target game's coefficient to find the equivalent setting.
Formula
canonicalPixels = sourceSize × pixelsPerUnit[sourceGame]
targetSize = canonicalPixels ÷ pixelsPerUnit[targetGame]
Example: CS2 size 2 → Valorant
canonicalPx = 2 × 2.0 = 4 px
valorantSize = 4 ÷ 1.0 = 4.0
The result is then clamped to the target game's valid range and rounded to its nearest step size — CS2 accepts integer-only values, Valorant accepts two decimal places, Apex uses one decimal. This ensures the output is always pasteable directly into the game settings menu.
Does Your Monitor Resolution Change Crosshair Size?
In most modern games, crosshair size scales with resolution. A crosshair set to 4 canonical pixels at 1080p will occupy 8 physical pixels at 1440p and 16 physical pixels at 4K — the same visual size relative to your screen. This means our converter is resolution-independent: the converted setting will look the same regardless of whether you play at 1080p, 1440p, or 4K.
However, this also means that a "pixel-perfect" dot crosshair (a single pixel centre only) does appear smaller on higher-resolution displays in absolute terms. Some players deliberately run stretched or lower resolutions to make their crosshair appear larger without changing the in-game setting — you can explore this further with our Resolution & PPI Calculator.

Frequently Asked Questions
What is the best crosshair size for CS2?
There is no universal "best" — but the data from top-ranked professionals points toward sizes 1–3 (2–6 canonical pixels). This range keeps the target fully visible while providing a precise aiming reference. Use our tool to find the CS2 size that matches your current Valorant or Apex setting so you can experiment without losing your reference point.
Why does CS2 size 1 not equal Valorant size 1?
Each game has its own renderer and unit system. CS2's crosshair size multiplier is calibrated to 2.0 pixels per unit; Valorant's is calibrated to 1.0 pixel per unit. That means CS2 size 1 = 2 canonical pixels, while Valorant size 1 = 1 canonical pixel — they look noticeably different on-screen.
Does crosshair size affect FPS performance?
Negligibly. Modern game engines render crosshairs in the 2D HUD layer — a trivial draw call compared to the 3D scene. However, if you play at very high resolution, your crosshair may appear smaller in physical pixels. Visit our Resolution Calculator to understand how resolution affects visual elements.
Should I copy a pro player's crosshair exactly?
You can use it as a starting point, but pro settings are tuned to the individual's monitor size, resolution, and DPI. A setting that gives s1mple a 2px canonical crosshair may render larger or smaller for you depending on your setup. Use the Reaction Rank Calculator to find your mechanical ceiling first, then dial in your crosshair to match your playstyle.
How accurate are the PixelsPerUnit coefficients?
Our coefficients are measured via pixel-ruler screenshots at 1920×1080 with each game running at default zoom. Values are accurate to within ±5%. Minor discrepancies can arise from anti-aliasing, OS DPI scaling, and renderer changes after game patches. We update coefficients after major game updates.
Why is Apex Legends' coefficient so high (6.0)?
Apex Legends uses a different internal unit system where the crosshair scale slider maps to a significantly larger pixel range per unit compared to CS2 or Valorant. A value of 1 in Apex occupies approximately 6 canonical pixels — which is why most Apex pros run values well below 1.0 (such as 0.5 or 0.3) to achieve a comparable visual size to their CS2 or Valorant counterparts.
