How to Check NFT Rarity (With Tools and OpenSea)

If you have a Twitter account, you've probably seen people posting about their "snipes" and "steals." Rarity plays a substantial part in the NFT ecosystem—some invest all of their time to get the rarest JPEG out of a freshly-minted collection for cheap. Despite the affection for rare NFTs, "How to check NFT rarity?" is a common question that often finds little to no answers.

Not to worry! I’m here to help. “How to check NFT rarity?” shouldn’t be a question absent from the discussion. It’s how so many of us pave our way into the big and bad blue chips of the space like Moonbirds or Azuki.

All you have to do is wait until a paper hand lists their rare NFT for floor price, cop it, then sell it for a higher price. Keep on doing this, and you’ll be buying your first Lambo in no time!

All jokes aside, finding NFT rarity is key to earning ETH in the industry. So enough bantering—let’s get into the details.

But first, what is NFT rarity?

Before finding out the answer to “How to check NFT rarity,” it’s best we get a grasp of what it means.

The rarity of an NFT is calculated by combining all individual attributes of a particular NFT in the collection. The less common the attribute, the less common the NFT.

Say you want to buy an ape in the BAYC collection… great choice! It’s one of the top projects for a good reason—celebrities and well-known crypto supporters have stamped their badge of approval on the project. 

Well, you can go down two routes here: you can either buy an ape with a combination of rare attributes, which would most likely sell for more, or you could sweep a BAYC off the floor with common traits.

Take BAYC #2651, with a rarity rank of 27. It’s currently going for a whopping 1,500 ETH!

What makes this particular ape rare is its low trait count, which only 2.54% of all other apes in the collection share. Add on its scarce fur, which is only seen in a staggering 0.77% of all apes, and you found a needle in a haystack.

On the other end, we have BAYC #1215. Its rarity rank is among the lowest—it sits at #9985 out of all 10,000 apes in the collection. Why? Quite frankly, its attributes are all common, except for its Navy Striped Tee. All other attributes are found amongst 12% or more of the total BAYC pool.

So how do I check NFT rarity?

I bet you’re wondering how I got all this information—we can finally get into the nitty-gritty. “How to check NFT rarity” has more than one answer, and the more you explore NFTs, the more solutions you’ll find.

First up: checking the collection on an NFT marketplace. Not the easiest route, nor will you see the rarity score of the NFT, but it’s perfect if you’re looking for particular traits.

What do I mean by all of this? First, take a look at CyberKongz’s OpenSea page.

You can sort by price, quantity, currency, and properties and even filter the entire collection to find the cheapest CyberKongz.

Say you want to get your hands on a CyberKongz with an AirPods trait. It’s cool, in with the times, and you get the added feature of flexing on all your friends. Fortunately, this trait is incredibly rare, as only 12 other CyberKongz share the same attribute. Cool huh?

Next: browsing through rarity tools. It’s by far the most efficient method, and you’ll be able to see the rarity score of each NFT. How convenient!

Funny how I mention rarity score—this is how most rarity tools measure and gauge the rarity rank of each NFT in the collection. To calculate the rarity score of a trait, follow this equation:

Rarity Score of a Trait Value = 1 / ([Number of Items With That Trait Value] / [Total Number of Items in Collection]).

Then, tally up the trait rarity scores, and you’ll get the overall rarity score. Bear in mind that there’s no need to calculate the rarity score on your own time. Various rarity tools do all the work for you, and you can search rarity scores through the collection with just a few clicks.

Also, there is more than one way to calculate NFT rarity, but the rarity score is the go-to for most collectors. It stresses single rare traits while considering the overall trait rarities for a particular NFT.

The best rarity tools

Rarity tools are a dime a dozen. You have everything from free tools to one-time payments to even monthly subscriptions. 

But, if I’m being honest with you, you’ll only ever need free tools. The difference between free and paid is negligible—especially if you’re just starting or have been in the game for a couple of months.

Let’s start off with the OG, the king of rarity tools if you could say. is the most popular and trusted platform on the market, and it has all the rarity scores you need to scratch that “How to check NFT rarity” itch on your mind.

BAYC's page

“What’s so special about it?” you might ask. All collections uploaded on the site must pay a fee, and it doesn’t come at a cheap price. Hence, the NFTs on the tools are legitimate and credible. Why would a rug puller pay extra to get their scam onto It doesn’t make any sense.

But there’s more to it than you think. Like OpenSea, you can filter by price, listing type, and traits. But, unlike OpenSea, you can filter by trait count and, most importantly, rarity rank. So instead of searching through rare NFTs by selecting a dozen rare traits, you can quickly set a range of rarity ranks and explore with ease. 

Don’t like looking at rarity scores? No worries—click the setting button underneath “Ranking Method Preset” and adjust the ranking method to your liking. Also, if you peep the top right corner, you’ll get the 7-day volume, 7-day average price, total volume, and owners.

Rarity Sniffer isn’t the only kid on the block—Rarity Sniffer is another contender, renowned for its ease of use and early uploads.

Aside from this, there isn’t much difference between Rarity Sniffer and The upcoming feature quickly lists newer collections, and the addition of a “Revealed” tab is perfect for mints-in-process.

One other thing: Rarity Sniffer has a strong Discord community, perfect for those gathering intel on NFTs and their respective rarity rankings.
