CS2 Pattern Seed Lookup Tool
Enter any pattern index (0-1000) to instantly see what patterns that seed produces across Case Hardened, Fade, Doppler, Marble Fade, and Slaughter skins. Essential for traders and collectors evaluating pattern-dependent skins.
How Pattern Seeds Work
Every CS2 skin has a pattern seed (also called pattern index) ranging from 0 to 1000. This seed determines the exact placement and appearance of the pattern on the skin. For pattern-dependent skins like Case Hardened, Fade, and Doppler, the seed dramatically affects value - with some rare seeds commanding 10x-1000x premiums over common patterns. You can find a skin's pattern seed using tools like CSGOFloat or the Steam inspect link.
Understanding Pattern Seeds in CS2
The pattern seed system is one of the most important yet often misunderstood aspects of CS2 skin valuation. Unlike float values which determine wear condition, pattern seeds determine the visual arrangement of the skin's design. This is crucial for pattern-dependent skins where certain seeds can multiply a skin's value exponentially.
What is a Pattern Seed?
A pattern seed (or pattern index) is an integer between 0 and 1000 assigned to every CS2 skin when it's created. This number determines how the skin's texture is mapped onto the weapon model. For most skins, the pattern seed doesn't significantly impact value - but for specific finish types, certain seeds are highly sought after by collectors and traders.
Pattern-Dependent Skins
The following finish types have patterns that vary significantly with seed:
- Case Hardened: Blue percentage varies dramatically (0-95%+ blue)
- Fade: Fade percentage from 80% to 100% full fade
- Doppler: Phase 1-4 plus rare gems (Ruby, Sapphire, Black Pearl)
- Marble Fade: Fire & Ice, Tricolor, Blue/Red dominant patterns
- Slaughter: Diamond, Heart, Phoenix, Angel patterns
- Gamma Doppler: Phase 1-4 plus Emerald variant

How to Find Pattern Seeds
There are several ways to discover a skin's pattern seed:
1. CSGOFloat Extension
The CSGOFloat browser extension automatically displays pattern seeds (called "paint seed" in their interface) when viewing items on Steam Market or in inventories. This is the most convenient method for regular traders.
2. Steam Inspect Link
Every CS2 skin has an inspect link that contains encoded information including the pattern seed. Various websites can decode this information. The pattern seed is part of the "D" parameter in the inspect URL.
3. In-Game Console
While inspecting a skin in-game, certain console commands can reveal pattern information, though this method is less convenient than browser extensions.
4. Third-Party Databases
Sites like CSGOStash and various pattern databases catalog famous seeds for specific skins, making it easy to identify valuable patterns by comparing screenshots.
Important Pattern Considerations
- Weapon-Specific: The same seed produces different patterns on different weapons. A #661 AK-47 Case Hardened is entirely different from a #661 Five-SeveN Case Hardened.
- Playside vs Backside: For knives especially, what matters is the playside pattern. Some seeds have great backsides but poor playsides - verify before paying premiums.
- Approximations: This tool provides estimated pattern results. Always inspect the actual skin or check screenshots before making purchasing decisions.
- Market Verification: Pattern premiums vary with market conditions. Use tools like our Pattern Value Estimator alongside pattern lookups.

Frequently Asked Questions
What is the rarest pattern seed?
Rarity depends on the skin type. For Case Hardened, seeds like #661 and #387 are among the rarest blue gems. For Doppler, Ruby (#900-933), Sapphire (#934-966), and Black Pearl (#967-1000) seeds are rarest. For Fade, seeds around #412-450 produce the highest fade percentages.
Can I change a skin's pattern seed?
No. Pattern seeds are permanently assigned when a skin is unboxed or traded up. There is no way to modify a skin's pattern seed. To get a specific pattern, you must purchase or trade for a skin that already has that seed.
Do pattern seeds affect all skins?
No. Many skin finishes have patterns that don't vary meaningfully by seed (like solid colors or simple designs). Pattern seeds only significantly impact value for finishes like Case Hardened, Fade, Doppler, Marble Fade, Slaughter, Crimson Web, and a few others.
Is pattern seed the same as float value?
No, they are completely different properties. Float value (0-1) determines wear condition (Factory New to Battle-Scarred). Pattern seed (0-1000) determines the visual arrangement of the pattern. Both affect value but in different ways.
How accurate is this tool?
This tool provides estimated pattern classifications based on known seed ranges. However, actual patterns can vary slightly, especially for borderline seeds. Always visually inspect skins before paying pattern premiums - the actual appearance is what matters, not the seed number alone.
