In short
Nano influencers (roughly 1,000 to 10,000 followers) usually have the highest engagement and the lowest cost, but you need many of them for reach. Micro influencers (roughly 10,000 to 100,000) offer a balance of reach and trust. Tier definitions vary by source, so judge by audience fit, not just the label.
The tiers in plain numbers
Definitions vary between platforms and reports. The ranges below are commonly used, and our other guides use slightly different bands, so treat them as a guide rather than a rule.
| Tier | Typical followers |
|---|---|
| Nano | 1,000 to 10,000 |
| Micro | 10,000 to 100,000 |
| Macro | 100,000 to 1,000,000 |
| Mega or celebrity | 1,000,000 and above |
What the benchmarks say
Benchmark reports consistently show engagement rates falling as follower counts rise. In the Influencer Marketing Hub benchmark report on Instagram, nano influencers averaged about 6.2% engagement and micro influencers about 3.9%. Other sources report similar patterns. These are global averages and vary by niche, platform and how engagement is calculated, so use them as a rough comparison, not a promise.
Nano vs micro, side by side
| Nano | Micro | |
|---|---|---|
| Reach per creator | Small | Moderate |
| Engagement | Often the highest | Strong |
| Cost per creator | Lowest; often products or small fees | Higher |
| Work to coordinate | High: many creators for the same reach | Moderate |
| Content quality | Varies a lot | More consistent, but still vet |
| Best for | Seeding, local campaigns, testing | Launches and steady campaigns for startups |
How to choose
- Start with your goal. Awareness across a wide area needs more reach; local trust or product testing suits nano.
- Look at budget and time. Managing 20 nano creators takes more effort than managing 5 micro creators.
- Check audience fit first. A well-matched small creator beats a mismatched larger one.
- Mix the tiers. Many brands run a few micro creators for reach and a group of nano creators for authentic content.
- Test and compare. Run a small pilot and compare cost per result.
For a first campaign, our startup playbook suggests a small pilot of nano and micro creators.
What about cost?
Rates depend on tier, format, usage rights and exclusivity, not just follower count. See our guide to influencer marketing costs in India for how to plan the budget.
