Not all rarity calculators use the same formula. Three major methods dominate the NFT space: Trait Normalization (Rarity Tools standard), Statistical Rarity (probability-based), and Weighted Rarity Score (subjective importance). Each produces different rankings for the same NFT. A top 500 NFT in one system might rank #1,200 in another. Understanding these differences is critical for comparing rarity across platforms.

Trait Normalization (Rarity Tools)
Sum of [1 / (Trait Count / Total Supply)] for each trait
- โขSimple and intuitive calculation
- โขEqual weight across all traits
- โขFast computation for large collections
- โขIndustry standard (OpenSea, LooksRare)
- โขIgnores trait category importance
- โขTreats optional traits same as core traits
- โขNo penalty for missing rare traits
- โขCan be gamed with many "None" categories
๐ ๏ธ Which Method Should You Use?
Trait Normalization is your best bet. It's the industry standard, used by OpenSea, LooksRare, and most marketplaces. Easy to explain, fast to compute, and widely recognized.
Statistical Rarity shows actual probability. A 0.0001% score means 1 in 1,000,000 chance of that exact trait combo. Great for collectors who value mathematical uniqueness.
Weighted Rarity Score lets you emphasize important traits. If community values "Fur" 2x more than "Background," you can reflect that. Most accurate for predicting market premiums.
๐ก Key Insight
Rarity scores are relative, not absolute. A score of 100 means nothing without contextโis that top 1% or top 50%? Always look at rank within collection, not raw score. Different methods produce different rankings, but top-tier NFTs (top 1-5%) tend to rank highly across all methods. If an NFT ranks top 500 in one system but #5,000 in another, investigate whyโthere might be a trait undervalued by the market that you can exploit. The best rarity tool isn't the most complexโit's the one the market actually uses.
