How many followers make you a nano, micro or macro influencer?

There is no official cut-off — every platform and every agency draws the lines slightly differently — but the market generally uses these orders of magnitude:

• Nano: 1,000 to 10,000 followers
• Micro: 10,000 to 100,000 followers (many sources count from 1,000)
• Macro: 100,000 to 1 million followers
• Mega: more than 1 million — the celebrity bracket

The lines shift because they measure only one thing: reach. What does change systematically as an audience grows is the relationship behind it — engagement drops and relevance thins out. A nano or micro account builds an audience around one niche; to most of their followers, a macro account is a familiar name, not a peer. Why that matters more to brands than the number itself: the difference between a micro and a macro influencer.

We use the tiers as bookkeeping, not as a selection criterion. Sunday Squad works with sportfluencers from 500 to roughly 25,000 followers — nano and small micro, with a lower bound deliberately below the textbook nano floor — because that is where the overlap between who watches and who actually trains is largest. The tiers tell you how many people can watch; they say nothing about who does something with it.
